Combining chocolate and peanut butter was probably one of the best inventions ever. The second best invention was making this cake.
Ingredients
  • 1 box chocolate fudge brownie mix, plus ingredients on back of box
  • 1 box yellow cake mix
  • 2 eggs
  • ½ cup oil
  • ½ cup crunchy peanut butter
  • 24 Reese's peanut butter cups, unwrapped
  • Peanut butter frosting (recipe and ingredients follow)
  • Reese's Pieces (about 1 cup)
  • PEANUT BUTTER FROSTING:
  • 1 stick butter, softened
  • ½ cup creamy peanut butter
  • Splash vanilla extract
  • About 3 cups powdered sugar
Instructions
  1. Preheat oven to 350 degrees F. Liberally grease a 13x9 inch baking pan with cooking spray and set aside.
  2. In a large bowl, combine the yellow cake mix, eggs, oil, and peanut butter until combined. Spread the peanut butter mixture evenly into the prepared pan. Place the peanut butter cups gently into the peanut butter dough base, 4 rows of 6 each. Top with the prepared brownie batter.
  3. Bake for approx. 30 minutes or until a toothpick inserted near the center comes out mostly clean, and center is set. Cool completely.
  4. Frost with the peanut butter frosting and top immediately with Reese's Pieces. Cut into bars and serve. Store leftovers airtight, for a couple days in the fridge.
  5. FOR FROSTING:
  6. In the bowl of a stand mixer, beat together butter, peanut butter and vanilla until creamy. Gradually add powdered sugar until frosting is fluffy but still soft (it won't be stiff like regular frosting but rather more soft like dough). Spread onto cooled bars.
