Equipment

Ingredients

  • 1 box cake mix 15.25 oz
  • 1/2 cup brown sugar
  • 3/4 cup butter softened
  • 1/2 cup peanut butter
  • 1 large egg
  • 1.5 cup quick oats
  • 1/3 cup mini chocolate chips
  • 1/3 cup m&ms
  • 4 tbsp water

Instructions

  • Preheat the oven to 350 degrees F. In a large mixing bowl, combine cake mix, water, egg, butter and peanut butter. Add oats and brown sugar, mix well. Gently fold in chocolate chips and M&Ms.
  • Spread the dough into a prepared 9x12 baking pan. (I used parchment paper for easier removal.)  **If you would like thicker bars, you can use a smaller 9x9 baking dish as well.
  • Bake for approximately 25-30 minutes, or until golden brown. Remove from the oven and let cool completely in the pan, before slicing.
