A giant monster cookie that's so thick, soft-baked, chewy, and loaded with all the monster cookie favorites. Oats, chocolate, peanut butter, and m&m's. This giant monster cookie makes for a great first day of school tradition too. Kids will love it as a fun after school snack to celebrate their first day.
It's no secret that I am a BIG fan of monster cookies! I just can't stop 🙂 Monster cookies are typically a combination of oats, peanut butter, chocolate chips, and m&m's. Basically all of life's essentials, right! We love monster cookie anything at my house.
By the looks of my blog's most popular recipes I would say you all love monster cookies too. These no flour monster cookie bars are the most popular recipe on the blog. If you want a fun twist to a monster cookie then be sure and try this monster cookie cheeseball dip or these no bake monster cookie dough bars.
Back-to-school is coming in a couple of weeks and I wanted to share my family's first day of school tradition. The first day of school can always be hard for kids. I remember as a little girl being so nervous for the first day. A new teacher. New classmates. Wondering if the other kids will like me or if I will have anyone to play with at recess.
No matter how stressful, bad, nerve racking the first day is, when you walk into your house and see a fun treat just waiting for you, things seem to be instantly better. I remember my own mother randomly have a delicious and warm after school snack for us.
This giant monster cookie, or I have also made this giant chocolate chip cookie, is our first day of school tradition. I make this while the kids are at school and it's waiting on the counter for them when they get off the bus. It's just a fun way to celebrate the first day and make it a memorable day for them.
It only takes minutes to make and it is crazy delicious out-of-this-world good. I would highly suggest getting a tart pan as the recipe calls for. It gives this giant cookie really pretty edges and the bottom of the tart pan comes out so it's really easy to cut this giant cookie.
Be sure and let it cool completely and then frost. Or you can leave the frosting off and it's still so delicious. I prefer it plain with no frosting but my kids love frosting so I'll usually put it on.
Back to School Traditions in my family
- Every year we do some back to school clothes shopping and then I pick a night and the kids put on a fashion show. They get to change into their new outfits and "model" them. My mom did this with me and my siblings as kids and I have so many fond memories from them. I still vividly remember our fashion shows even decades later at 33 years old.
- I surprise my kids and make invites for a 'back to school' party. I make a fun dinner or order out. Decorate the house with balloons and streamers, just anything fun like that. I usually give them the invite the night before and tell them to meet in the kitchen in the morning for the party. Every year it's something different. We might go to the lake, go to Chuck-e-Cheese's, go ride the animals at the mall, etc. It can be whatever you want it to be. I also give them a small back to school gift. It's usually something they have been wanting. For my son it's usually a Lego set and my daughters both love Shopkins. This is a fun day to celebrate going back to school. The kids love this one.
- A new first day of school outfit. When kids are nervous, having a cute outfit on, newly painted nails, or new shoes, or new earrings on can make ALL the difference in their confidence. I love helping them pick out the outfit the night before and my girls love getting a special pair of earrings for their first day. Or a special jewelry like a bracelet or something. Just something that they can remember that mommy is thinking of them while they're gone.
- I always make this giant monster cookie every year. It's waiting for them on the counter when they get home from school. It's a fun once-a-year surprise that they look forward to.
What are some back-to-school traditions that you do? I love this time of year and I also love creating memories with traditions for my kids.
Something as simple as a giant monster cookie waiting for you at home on the 1st day is enough for so many memories for our kids.
Giant Monster Cookie
Giant Monster Cookie
- 1/2 cup (1 stick) butter, softened
- 1/2 cup creamy peanut butter
- 1 cup light brown sugar
- 1 large egg
- 2 teaspoons vanilla extract
- 3/4 cup all-purpose flour
- 1 teaspoon baking soda
- 1 teaspoon cornstarch
- 1/4 teaspoon salt
- 1 1/2 cups quick oats
- 1 cup mini chocolate chips
- 1 cup mini m&m's
Chocolate Frosting (optional)
- 1/2 cup (1 stick) butter, softened
- 1/4 cup cocoa powder
- 1 1/2 cups powdered sugar
- 2-3 tablespoons heavy cream
- Preheat oven to 350 degrees. Spray a 11" tart pan with cooking spray.
- In a large bowl (or bowl of a stand mixer) cream together the butter, brown sugar, and peanut butter until light and fluffy, about 3-4 minutes. Mix in the egg and vanilla, scraping down the sides of the bowl as needed.
- In a separate bowl, add the flour, baking soda, cornstarch, and salt and whisk to combine. Add the flour mixture to the wet ingredients and mix until just combined.
- Add the oats, chocolate chips, and M&M candies. Mix on low speed just until dough is combined.
- Spread dough into the prepared tart pan and press evenly with your fingers. Sprinkle a few extra chocolate chips and m&m's on top and gently press down.
- Cook for 16-20 minutes or until lightly golden brown. It will cook more as it cools so you don't want to overcook it. Mine is done at 16 minutes. Remove from oven and let cool completely on a cooling rack.
- If wanted pipe on some chocolate frosting: Whip butter in a bowl with a handheld blender until light and fluffy. Add cocoa powder, powdered sugar, and heavy cream and mix. Use more or less powdered sugar and heavy cream depending on the desired consistency. Pipe onto edges of cooled cookie and decorate with additional m&m's.
