Ingredients

Bars

  • 1/2 cup unsalted butter, softened to room temperature
  • 1/2 cup granulated sugar
  • 1/2 cup brown sugar (dark or light)
  • 1 large egg
  • 2 tsp vanilla extract
  • 1 cup + 2 Tbsp all purpose flour
  • 1/3 cup dark chocolate cocoa powder (regular unsweetened cocoa powder is fine as well)
  • 1/2 tsp baking soda
  • 1/2 tsp salt
  • 1/4 tsp espresso powder; optional--the espresso enhances the chocolate flavor
  • 1/3 cup M&M’s® Crispy
  • 1/3 cup peanut butter chips
  • 1/3 cup semi-sweet chocolate chips

Crust

  • 1 1/2 cups graham cracker crumbs (about 12 full sheets of graham crackers)
  • 1/2 cup unsalted butter, melted
  • 1/3 cup granulated sugar

Topping

  • About 1/4 cup M&M’s® Crispy

Instructions

Bars

  • With a mixer, cream butter until light and fluffy, about 1 minute. Add in brown sugar and white sugar and mix until well combined.
  • Add in the egg and vanilla extract. Mix.
  • In a separate bowl, sift together flour, cocoa powder, baking soda, salt, and espresso powder. Once combined, slowly incorporate dry ingredients into wet ingredients. Mix until just combined.
  • Add in M&M’s® Crispy, peanut butter chips, and semi-sweet chocolate chips. Mix. Once combined, chill dough in refrigerator for about 20 minutes (this makes the dough easier to work with).

Crust

  • Preheat oven to 350 degrees. Line an 8x8 baking pan with non-stick foil with enough overhang on the sides.
  • Combine melted butter, sugar, and graham cracker crumbs. Press in an even layer in the bottom of the pan.
  • Remove the cookie dough from the fridge, and press into the pan in an even layer.
  • Bake for 25-30 minutes, or until the bars are set (slightly firm to the touch). Because I like my bars a bit on the gooey side, I baked mine for 25 minutes exactly.

Topping

  • While the bars are cooling, press M&M’s® Crispy into the dough for a nice finishing touch.
  • Once the bars have cooled (for best results, allow to cool at least 30 minutes), lift the foil from the pan and cut into squares.
  • Enjoy!
