CHOCOLATE CAKE WITH PEANUT BUTTER FROSTING
TIPS FOR MAKING REESE'S PEANUT BUTTER CUP CAKE:
I like to use margarine in the frosting for this recipe for one main reason. Because of the high vegetable oil content in margarine, I found it helps to keep this frosting soft and creamy. But if you are just totally adverse to using margarine, please feel free to use real butter. Also, if you cannot find the Reese's peanut butter, just use your favorite creamy peanut butter, it will still come out amazing!
