(no flour) Monster Cookie Bars

No flour monster cookie bars are the perfect back-to-school snack! They freeze really well and who can resist these bars loaded with oatmeal, peanut butter, chocolate chips, and m&m’s?!

Monster cookie bars loaded with oats, peanut butter, chocolate chips, and m&m's. Plus, they have no flour in them! No flour monster cookie bars are delicious and perfect for a crowd.

 Are you ready for back-to-school? This is my first year sending a child to “real school”, like at an elementary school where he is there all day and rides the bus. I’m so nervous but yet so excited. I know he will love it.

With back-to-school comes the dreaded, “I’m starving mom!” the second they walk in the door. I remember doing that growing up, so I am sure my sweet little kindergartner will do the same thing. These no flour monster cookie bars are so delicious and perfect for an after school snack to fill their little bellies after a long day. The recipe makes an entire cookie sheet, so I always freeze some and pull them out when needed. I just put a couple in a Ziploc bag and freeze them that way. They only have to sit out for several minutes to thaw a bit or you could microwave for 20 seconds or so.

No Flour Monster Cookie Bars are loaded with oats, peanut butter, chocolate chips, and m&m's. They bake in a cookie sheet and make enough to feed a crowd. Plus, there is no flour in them!

 I mean, seriously!? WHO can resist that? I am a sucker for all things monster cookie. The combo of peanut butter, oats, and those cute mini rainbow m&m’s just can’t be beat.

I will note that this recipe calls for both quick oats and old-fashioned (regular) oats. You could use all quick, but I have found that using all quick oats results in a tough/dense cookie bar. Splitting the oats results in a soft and delicious cookie bar. Another tip is to use a pizza cutter to cut these into squares. I do that every time and it’s so easy!

Don’t be alarmed if the batter is hard to spread into the cookie sheet. It takes me several minutes to work it and manuever it to fit in the pan. I spray my hands with cooking spray and it seems to always help. Readers have also let me know that if you use the butter wrapper to spread the dough, that it makes it easier too. So, try these tips if you are having trouble.

(no flour) Monster Cookie Bars

I find the bags of mini m&m's in the baking aisle or the candy aisle in the grocery store

The bag (about 10 oz) of mini m&m's comes with about 1 1/2 cups of m&m's inside of it. I just use the whole bag. It's less than the 2 cups called for. So, use 1-2 cups of the m&m's. Whatever you prefer.

These bars right out of the oven will look like they are not done. Trust me, they firm up and come together so nicely while they cool. I would not recommend cooking for more than 20 minutes (mine never take that long). Edges should be a light golden brown and the middle should still look under-done and pale.

Ingredients

  • 1 cup packed brown sugar
  • 1 cup granulated sugar
  • 1/2 cup (1 stick) salted butter, softened
  • 1 1/2 cups creamy peanut butter
  • 3 large eggs
  • 1 tablespoon vanilla extract
  • 1 1/2 cups quick oats
  • 3 cups old-fashioned oats
  • 1 teaspoon baking soda
  • 1-2 cups mini m&m's
  • 1 cup mini chocolate chips

Instructions

  • Heat oven to 350 degrees. Prepare a cookie sheet by lining it with parchment paper, silpat liner, or spray with cooking spray.
  • In large bowl, or bowl of a stand mixer, combine brown sugar, granulated sugar, peanut butter, and butter. Beat until pale in color and fluffy.
  • Add the eggs and vanilla extract. Blend together.
  • Add in the oats and baking soda. With a rubber spatula or wooden spoon, mix by hand until combined.
  • Add in the m&m's and chocolate chips (reserve some for top of bars if wanted). Stir together well until combined.
  • Dump onto your parchment lined cookie sheet and spread out. This will take several minutes, but it can be done. Sprinkle the reserved m&m's and chocolate chips on top (if wanted). Press down slightly into dough.
  • Bake for 17-20 minutes. The edges will be lightly browned and the middle will still look pale and underdone, but it will finish baking as it cools. Let cool for at least an hour so the bars can firm up and come together. You do not want to over-bake these!

 Surprise your kids with these on their first day of school! My kids LOVE these bars and I love that they’re filled with oats and peanut butter to keep them full.

    August 12, 2015 at 10:55 pm In the instructions the peanut butter was left out. When do you add the peanut butter? Also, will it work substituting in sunbutter for the peanut butter due to peanut allergies?

      August 13, 2015 at 9:29 am Hi Edith! Thank you for catching that mistake. I will go fix it right now. You add the peanut butter in with the butter and sugars. I have no knowledge or experiences with sunbutter, so I am not sure if it would be a good substitute. I would imagine if it's the same texture of peanut butter it would work just fine. Thanks so much for leaving your comment and visiting :)

        August 17, 2015 at 10:37 pm Sunbutter works but makes the dough greasy...WOWBUTTER is also another peanut free brand and it isn't as greasy...we have nut allergies here too...and it taste exactly like the real stuff.

        April 21, 2016 at 3:40 pm Can I use a pan (like a casserole dish) instead of a cookie sheet? The cookie sheet I have is 16" x 11" so I'm afaid the bars will overflow the edges.

          April 21, 2016 at 6:03 pm Like a casserole dish, as in 9x13 baking dish? I would say no because the the bars would be too thick and would never cook in that smaller dish. You could try cutting the recipe in half and putting in a 9x13 casserole baking dish. The recipes calls for a standard size cookie sheet (w/ sides), I don't know the measurement off the top of my head but I included it in the recipe. Hope that helps you :)

According to what it says, oats are considered safe and gluten free..... hopefully that helps you.

    • Reply

      August 19, 2015 at 8:11 am Hi Joy :) Yes you would have to use oatmeal to make these monster cookie bars. Monster cookies are normally an oatmeal, peanut butter, m&m, chocolate mix. If you don't want to use the oatmeal try just making a chocolate chip cookie bar. I've made this one before and they are really yummy. http://www.thebakerupstairs.com/2012/11/chocolate-chip-cookie-bars.html Thanks for visiting and commenting. Have a great day!

      August 19, 2015 at 1:48 pm Hi Cindy! I would say no to the 9x13 pan. There will be way too much dough and I don't think it will ever cook all the way. If you wanted to use the 9x13, try cutting the recipe in half and that should be ok. I've never halved it because these freeze so well.

    August 20, 2015 at 11:35 pm Have you made these with all regular oats- no quick cook?
    • Reply
      Together As Family
      August 20, 2015 at 11:48 pm I have never done that. You can use all regular oats, but it may affect the texture. The quick oats are ground finer than regular, so it provides more "substance" to hold the bar together. You may have to use slightly more than the 4 cups oats called for in the recipe if you use all regular :) I hope that helps.

    August 20, 2015 at 11:47 pm As the recipe stands now it is not gluten free! You would need to make sure you use gluten free oatmeal. Also double check your vanilla extract.

      August 20, 2015 at 11:51 pm Hi. I never said these bars were gluten free. I know nothing about what qualifies as gluten free which is why in the title I put "no flour" instead of gluten free. As far as the vanilla extract. It's correct. I've made these dozens of times. The recipe makes an entire cookie sheet, so you do need the tablespoon of vanilla extract. I know it may look like it's too much, but I assure you it's right :) Thanks for visiting and commenting.

        October 29, 2015 at 2:46 pm Throwing out my learned tidbit, extracts are not gluten-free unless the label clearly states that it is. I know this is not labeled gluten-free but so easily can be. Also, could be dairy free by using "earth balance" spread and "enjoy-life" chocolate

    August 21, 2015 at 11:30 pm I have no idea what I did wrong. I cooked for even longer than the recipe called for and they were brown on the edges. Looked and smelled great. But the middle was goopy and raw. It was kinda disappointing. Baking isn't cheap and they are inedible. Thoughts?? Thanks!

      August 22, 2015 at 8:27 am Oh shoot! I'm sorry they did not turn out. I know about the "baking isn't cheap.... I've had some bad experiences". It sounds like you did everything right. The edges should be a light brown and almost paler in color. Every time I take my bars out of the oven I think "those are not done, I better put them back" but I resist. Did you let them sit and cool for awhile? They will firm up and come together as they cool. I've made these several times since posting the recipe, but I will read back through and make sure it's all how it should be. Was your butter melted? That can make a difference. It just has to be softened. I know some people don't notice a difference, but did you use both kind of oats? I've noticed with all quick or all regular, the texture is a bit off. That's why I think the mix of both is better, and holds the bars together (because there is no flour). I just double checked the bake time and it's correct. Mine always come out at 19 minutes. I want to help, so let me know :)

        August 22, 2015 at 8:44 am One more thing: your baking sheet should be the regular cookie sheet with sides, also called a half-sheet, or a jelly roll pan. It should measure roughly 12"-13" x 18". I just went and measured mine :)

          August 23, 2015 at 2:45 am different Rebecca here, I just made them and was very worried when I pulled them out. I put mine back in for a couple more minutes because I cook on stone and most if my stuff needs a few more minutes than normal. (my oven temp may be off as well.) Anyway, they still looked uncooked when I pulled them out, but they did firm up perfectly and were so yummy! I had a small amount of white chocolate chips leftover from something else, so I threw those in too. yumm!!

          August 19, 2016 at 8:37 pm yes, you can bake them as individual cookie, they should be just golden brown on the edges and will look soft, but slightly puffy in the middle. You can substitute GF oats, vanilla to make them GF and if substituting sunbutter you can use 1/4 c. less shortening/oil if they are too greasy. I'm a professional home economist and adjusting the size of the pan to what you have means adjusting the baking time to make sure you bake the product until you get the results you want. Bake on a 9 x 13 pan and put the other half in the frig for later. No two ovens are ever exactly the same, so one should know what they should look like, when it is time to take it out of the oven. Brown around the edges, slightly puffy, but soft/doughy in the middle should serve the purpose. Just like cupcakes are individual cakes, cookies are individually proportioned bars. You can also turn your oven heat down 25-50 degrees and bake fatter bars or put individual servings into a mini cupcake pan to make these into petit fours. Almost any cookie recipe makes into bars or a giant cookie, just as easily as it makes individual cookies ready to grab and go. If you make adjustments to fit your personal dietary needs, make notes so you remember what you did and know most kids will eat your mistakes, even if you think they are gross. It's sugar, chocolate and oatmeal. If they are underbaked, pop each cookie/bar in your microwave wrapped in a paper towel for about 30 seconds and wall-la it is now done! Happy Baking!

    September 3, 2015 at 10:28 am These are amazing!!! Perfect for my Celiac sister. I just made sure to use gluten free oats, which I could only find in old fashioned oats. Worked out fine without using any quick oats. I just added an extra half cup. I also added an additional 1/2 cup of peanut butter, and instead of 2 cups of mini m&ms I used one cup plus one full medium size bag of peanut butter m&ms. I don't have a jelly roll pan so I used a 16×12 inch cookie sheet with higher sides and cooked it for 25 minutes. They came out perfect! And using a pizza cutter was a great tip!!

I used all old fashioned rolled oats, and added in a cup of raisins because I've always like the flavor a little dried fruit gives to this type of recipe. They still baked up fine, and I just portioned them out into lunch bags and added them to the family "snack" container.

    October 13, 2015 at 4:23 pm I rarely comment on anything (due to sheer laziness), but I just made these and they're amazing!! I must admit I'd eaten an entire row before they'd cooled for even 10 minutes, but they're delicious, I can see me making these often (which is probably a bad thing......). Thanks for the recipe! P.S. I'm glad they're "no flour," but holy moly people need to calm down with the negative remarks. If you want them to be gluten free, make them gluten free! Easy!

    October 29, 2015 at 6:00 am We made these last night and they are very good. You are correct about the cooking time, got to keep a close eye on these babies! When they are just starting to brown they come out (I accidentally baked mine a couple minutes too long but they still came out good!). I would love to try making these again (and again) using the silicone sheets you suggest in the instructions. Thanks for the recipe.

      October 29, 2015 at 7:51 am Yes you do. I always (always!) take mine out right at 9 minutes. They usually look like they are not done, but after letting them cool they are always perfect! I'm so glad they were still yummy. If you get the chance try those silicone baking sheets. You will love them and I feel like they help things not burn as easily. The ones made my amazon are the best price I have ever seen, same quality as the name brand for a fraction of the cost. I use them! Thanks so much for commenting.

      October 31, 2015 at 10:19 am Thanks Trisha! I'm so glad everyone loved them. I have fixed the directions to include adding the extra m&m's/choc chips on top before baking. My mistake. Thanks for pointing that out and coming back to leave a comment :)

      November 14, 2015 at 4:11 pm Hey Karen. I have not heard of any readers trying applesauce. You could try replacing half of the butter with it?? In addition, readers have said they have cut the sugars down to 1/2 cup each and it has been fine. It does also make an entire cookie sheet. I usually get around 45 bars when I make these.

    December 11, 2015 at 2:40 pm Thank you so much for posting this! I was looking for some gluten free treats for Christmas and these are perfect. I added mini marshmallows to the top and got the mini Christmas m&ms and they look and taste amazing. I love that I can store these in the freezer and pull some out when I need to make a cookie tray. Thanks!!!

      December 11, 2015 at 6:24 pm Hi Becky! I'm so glad you love them. I love the idea of using the Christmas m&m's. I actually have a bag sitting in my pantry and I think you gave me a reason to use them now :) And marshmallows! Yum! I always freeze a bunch of these and pull them out as needed. Thanks for your sweet comment.

    February 12, 2016 at 6:51 pm I made these today, followed the recipe to a T and ended up taking them out of the 350 degree oven at 20 minutes because at 18, they were not even set in the pan. I also put them back into the oven later because it was like eating a scoop of dough and baked them for another 10 minutes. They are lightly golden at the edges, but they still are not done. They are totally cool now but it is still like eating a spoon (because they do not come close to staying in a bar)of raw dough. I do not have a clue what happened. I followed the recipe exactly, but no idea why they did not bake. The dough filled to the top the 1/2 sheet cookie pan (11 1/2 by 18). I wonder if the old-fashioned oats should be reduced from 3 cups. The batter was very very thick, so thick that it took some time to even it out in the pan. Something definitely was not right and I may try to make it in a full-size cookie sheet next time, should I decide to try it again. I know you say that it should not be baked for over 20 minutes, but had I not, it would have been inedible.

      February 12, 2016 at 8:11 pm Hi Jan, let's see if we can figure this out. I make these bars all the time and we love them, so I really want them to work for you. You mentioned the batter being very thick and that is exactly how it should be. It takes me several minutes to spread it out into the cookie sheet. Speaking of cookie sheet, you did use the correct one so i know that's not the problem. The only four things I can think of that might cause problems are: 1) I always think the bars are gooey and underdone when I pull them out, but once you let them cool for at least an hour, they firm up and come together. 2) The peanut butter. Don't use natural or any other different type of peanut butter. Just regular, full-fat, normal peanut butter. 3) Was the butter melted when you added it? Make sure the butter is room temperature soft. 4) Did you use both kind of oats? The quick oats provide more bulk to the recipe because there is no flour. The old-fashioned oats provide the texture. It seems odd, but you do need both kinds. Could any of those have been the problem? I honestly don't know what else it could be. I know it can't be altitude because I live in Maryland where it's low/sea level, and my sister who lives in utah (super high altitude) bakes these all the time with success. I'm so sorry. I hate it when recipes don't work out. Let me know if you have any more questions :) Thank you for leaving your comment. I love answering questions and helping people out with the recipes.

        February 13, 2016 at 12:27 pm I don't know what happened, but these are definitely not like yours are pictured. They are thick and dry and not at all what I hoped. Even my husband says he thinks that you made a mistake with the size of the pan. He helped me spread them out in the pan and even before I baked them, he was expressing doubt. I went back and measured the pan to make sure that it was the correct size. I just know that I am not happy with these the way they came out for me. They were not set at 20 minutes - there was absolutely no sign they had started baking and when I lifted one corner of the pan to check the bottom (I lined with parchment paper), they looked like unbaked cookie dough, no color at all to the dough at the sides or the bottom. I did do everything you said - Jif peanut butter, soft butter, let them cool for an hour after the 20 minutes and when I tried to cut them, it was still like cutting cookie dough, there was no bake to them. I used both types of oats, I had to buy the old-fashioned and bought the quick as well just in case I didn't remember that the oats I had at home was quick. I may try them again reducing the old-fashioned oats (you mentioned in one of the comments about 4 cups of oatmeal - your recipe calls for 4 1/2 cups). Or I may try a full size cookie sheet.

          February 13, 2016 at 2:50 pm Well, it sounds like what you did was correct. I have no clue as to why they would not turn out. Other have made these with success and I make them at least once a month since posting the recipe. I double checked the recipe, pan size and everything just to make sure and it is all correct. I'm sorry they didn't work for you.

    February 22, 2016 at 6:34 pm We love these bars at our house! I tweaked the recipe by cutting out the white sugar completely and making it 2 cups of quick oats rather than 1.5 cups. I never even get the chance to freeze them because they are gone to quickly!

    February 25, 2016 at 10:09 am I just made a variation of this and LOVE it!!!! I cut down on the chick plate chips and no M&Ms. Instead I added some unsweetened coco powder, coconut, walnuts, dried cranberries and raisins. I added 3/4 cup of Nutella and cut the peanut butter down to 3/4 cup. I also used all old fashioned oats, but cut it down by a half. These turned out AWESOMELY!!!! My son couldn't wait for them to cool down so he could try them, I can't blame him!!!! DELICIOUS!!!!

      March 31, 2016 at 12:52 pm Hi Kristi. I've made these dozens of times and I have always used the pizza cutter to cut them while they're still on the silicone mat. I've never had it cut the mat. If you're worried you can also use parchment paper or even tin foil instead, to line the cookie sheet.

    April 11, 2016 at 12:10 am Can you substitute out the peanut butter? I'm not a nut fan...

      Together As Family
      April 11, 2016 at 9:38 am I have never done that, but other readers have said they've used something called 'sun butter'?? I guess it's like peanut butter but not nuts. Again, I am not for sure on that as I've never done it. Monster cookie recipes traditionally have peanut butter, so if you don't like the peanut butter you'd be better off making a chocolate chip oatmeal bar or chocolate chip cookie bar :) Hope that helps! I've made this one before and it was yummy: http://www.thebakerupstairs.com/2012/11/chocolate-chip-cookie-bars.html You could even use the m&m's in place of the chocolate chips.

    April 20, 2016 at 4:42 pm Oh my word, these are dangerous!! Made them with just a few changes- one cup mini chips, one cup butterscotch chips, and slightly over one cup full sized m&ms. Holy Hannah......I'm gonna have to work out like an animal! The butterscotch gives them such an amazing flavor. Next time I'm going to try and half the sugar- try to get them a LITTLE healthier-- since I'm bound to eating them a LOT! Thank you for this amazing recipe. I'll re-comment after I change the sugar and let you know how they do.

      April 21, 2016 at 6:00 pm Yum, butterscotch chips sound fabulous in these :) I love that these cookie bars are so adaptable. I have had readers say that they have cut the sugar by as much as half, and they turned out fine. I've never done that myself, so I'm not for sure about that. But, all those chips & mini chips provide lots of sugar so I'm sure it would still be delicious with less sugar. Thanks so much Wendy for coming back and leaving your comment. I would love to hear how a less-sugar recipe works for you!

I'm signing my recipes up with www.myrecipemagic.com where they will tell you the nutrition information. I hope to have that set up in the next few days. You could always google one of those nutrition sites where you can input the recipe and then it tells you all the nutrition facts too, if you want it right away. Thanks for letting me know you like these. And, I agree, I freeze some every time I make them and they freeze great :)

    May 21, 2016 at 3:21 pm I didn't have quick oats, so I used my food processor on some of the oats to make them more like flour. They seem to be fine. The batter is wonderful and the cookies are delicious, of course. If someone has a batch that doesn't turn out right, scoop out the gooey part and bake that on another pan. Or even microwave it. Watch carefully! These look so pretty, not gooey at all! Next time, coconut, maybe some walnuts...this recipe is so versatile! Thanks for posting and I love your VERY polite and considerate replies. You are so gracious!

      May 21, 2016 at 5:15 pm Hi Pam. What a great idea to blend up some oats to make the finer quick oats! I know a lot of people have asked about using both kinds of oats, and I really think you need both textures for these bars since there is no flour. Thanks for sharing your solution. And thank you for your kind words. Good or bad, I just really love and appreciate people who take the time to visit and comment. Have a great weekend :)

    August 17, 2016 at 3:49 pm These are amazing! I subbed 4 Tbs coconut oil for 4 Tbs butter and at 19 mins they were perfection! A trick for getting them patted down easily is to spray your hands with cooking spray, it makes the process so much quicker because the batter doesn't stick to you!

    April 14, 2017 at 5:09 pm I need help quick! I made these for a church event this evening. I baked a few mins longer than stated, but even after cooking an hour they are still gooey inside and not set up! Should I put them in the fridge or back in the oven?? they are slightly still warm.

      April 14, 2017 at 10:13 pm I have never had to cook these for an hour! That seems like a long time for them to still not be cooked. They do have to set up and cool for about an hour after baking. They will be loose and not hold together right after they come out of the oven, but after cooling they always come together and set up. I honestly have no idea what it could be. Did you follow the recipe exactly? It sounds like maybe an ingredient was left out or swapped with something else?? If they have already cooked for an hour and are still gooey then I am not sure they can be saved.

        April 15, 2017 at 12:57 am I'm so sorry, I didn't double check before sending. I baked for maybe 20 mins or so and then that should have been "cooling" for an hour, not "cooking". I'm so sorry! I put them back in the oven and they turned out great! I'm not sure if my oven temp is off and they just needed to bake longer or what. I used a silpat mat, next time I think I'll just spray my pan, I'm not sure if that had anything to do with it. Thanks for getting back with me and for the yummy recipe!

So much so that my boss requested I make them for the annual meeting luncheon with 50 guests. Once again they received rave reviews. I have given out a link to your site and this recipe more times than I can count - they are that good! Generally I am not a fan of the oatmeal/chocolate combination, I'm an oatmeal/raisin girl, but these are the exception because they are exceptional! Thank you for the recipe!
