  • Total Time: 22 minutes
  • Yield: 24+ bars (depending on size) 1x




  • 1 box devils cake food mix (I used Betty Crocker)
  • 1/2 cup (1 stick) butter, softened
  • 1 egg


  • ¾ cup butter, softened
  • 1 cup peanut butter
  • 1 teaspoon vanilla
  • 3 cups powdered sugar
  • 2 tablespoons half & half
  • Pinch of salt


  • 1 cup milk chocolate chips
  • 1 cup semisweet chocolate chips
  • 2/3 cup whipping cream



  1. Preheat oven to 350°F.
  2. In medium bowl, mix crust ingredients; press in the bottom of an ungreased 9×13 baking dish  (mixture will be thick). Bake 13 minutes. Cool completely, about 30 minute


  1. In bowl of a stand mixer (or you can use a hand mixer), combine softened butter and peanut butter and mix until smooth. Add powdered sugar, vanilla, salt and half & half and mix until smooth and velvety.   Spread evenly over cooled crust.


  1. Place the chocolate chips in a medium size bowl. Microwave or heat the cream on the stovetop to a low simmer (a few small bubbles around the edges). Pour the cream over the chocolate chips. Let sit for 2 to 3 minutes then whisk to combine until smooth and glossy. Let cool slightly and then spread ganache over peanut butter filling.
  2. Let stand at room temperature until bars are set, 2 to 3 hours.
  3. Cut into desired size squares and serve.
