Ingredients

  • 1 box (15.25 oz) yellow cake mix (DO NOT prepare)
  • 1/2 cup brown sugar
  • 3/4 cup (1 1/2 sticks) butter, softened
  • 1/2 cup creamy peanut butter
  • 2 tablespoons water
  • 1 large egg
  • 2 cups quick cooking oats
  • 1/2 cup miniature semi-sweet chocolate chips
  • 1/2 cup mini m&m's (plus extra for top of cookies)

Instructions

  • Heat oven to 350 degrees. Line cookie sheet with parchment paper or spray with cooking spray. 
  • In large mixing bowl, combine cake mix, brown sugar, butter, peanut butter, water, and egg. Beat with a handheld blender on medium speed until well combined. 
  • Add oats, chocolate chips, and mini m&m's. Stir with a wooden spoon. 
  • Use a cookie scoop to scoop out dough. They should be about the size of a golf ball. Bake for 12-14 minutes. Cookies will not spread much at all.
  • Press a few additional m&m's onto the tops of the cookies when they come out of the oven. As you press them on, the cookie will flatten slightly and look more like a traditional cookie shape. Let cool on cookie sheet for 15 minutes so they can come together and set up. 

Notes

I used a box of Pillsbury supermoist yellow cake mix.
 
I have only ever used the quick oats in this recipe. They have a finer texture so if you use old-fashioned oats the oat flakes will be larger and give more texture and chew to the cookie. 
 
I would recommend not using the all-natural peanut butter in this recipe. It tends to dry out baked goods. But again, you can use it I just can't promise the outcome will be good.
