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
  1. With a mixer, cream butter until light and fluffy, about 1 minute. Add in brown sugar and white sugar and mix until well combined.
  2. Add in the egg and vanilla extract. Mix.
  3. 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.
  4. 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
  1. Preheat oven to 350 degrees. Line an 8x8 baking pan with non-stick foil with enough overhang on the sides.
  2. Combine melted butter, sugar, and graham cracker crumbs. Press in an even layer in the bottom of the pan.
  3. Remove the cookie dough from the fridge, and press into the pan in an even layer.
  4. 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
  1. While the bars are cooling, press M&M’s® Crispy into the dough for a nice finishing touch.
  2. 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.
  3. Enjoy!
