Thick & Chewy Monster Cookie Bars
These Monster Cookie Bars are supremely thick, chewy, hearty, and packed with amazing flavor from peanut butter, chocolate, and miniature M&M's candies! A must-try, and so much easier than making drop cookies!
Servings: 15 -18
- 3/4 cup unsalted butter softened
- 2 cups brown sugar
- 3/4 cup creamy peanut butter
- 2 large eggs
- 1 Tbsp vanilla extract
- 1 tsp baking powder
- 1/4 tsp baking soda
- 1/4 tsp kosher salt
- 2¼ cups all-purpose flour
- 1½ cups old-fashioned oats not quick oats
- 3/4 cup chocolate chips
- 1 cup miniature M&M's candies
Preheat oven to 350 degrees F. Line a 13x9" rectangular baking pan with foil, extending the sides of the foil over the edges of the pan. Spray the foil liberally with cooking spray; set aside.
In the bowl of a stand mixer, cream together the butter and brown sugar until smooth and fluffy, about 1 minute. Beat in the peanut butter, followed by the eggs and vanilla. Add in the baking powder, baking soda, salt, and flour and mix on low-speed until just barely combined. Beat in the oats, chocolate chips, and M&M's candies until just combined.
Press the dough into the prepared baking pan evenly and bake for approximately 20-30 minutes or until the top is golden brown and set. Cool in the pan completely before cutting into bars.
