i made these for superbowl sunday and man did they go quickly! i used my favorite, chocolate mayonnaise cake recipe, and then used choc/peanut butter chips for the icing... they were AWESOME! the peanut butter was subtle, which i liked. i think maybe next time i can try to whip some peanut butter by itself to make it a bit lighter and fill the center of the cupcakes with it to create a reeses cupcake!!
