For the Cake
1 box devil’s food cake, plus ingredients called for on box
2 c. peanut butter, melted
1 c. chopped Reese’s
1 c. Reese’s pieces
For the peanut butter frosting
1 c. peanut butter
10 tbsp. unsalted butter, softened to room temperature
2 c. powdered sugar
2 tsp. pure vanilla extract
1/4 tsp. kosher salt
1-2 tbsp. heavy cream
Bake cake: Preheat oven to 350° and line a 9-x-13” pan with parchment paper. Prepare cake batter according to package instructions and pour into prepared pan. Bake until a toothpick inserted into the middle of the cake comes out clean, about 25 minutes. Let cake cool completely.
Using the back of a wooden spoon, poke holes all over cake. Then pour melted peanut butter over the entire cake, filling the holes. Set aside.
Make frosting: In a large bowl, using an electric mixer, cream together peanut butter and butter. Add powdered sugar, vanilla and salt and beat until light and fluffy. Gradually beat in cream to loosen frosting, if needed.
Spread frosting all over the top of the cake. Top with chopped Reese’s and Reese’s Pieces and chocolate syrup
