Peanut Butter Cupcakes

This is, AGAIN, from the Primrose Bakery book. It's the opposite of what I always make - chocolate cupcakes with peanut butter frosting. The cake is quite dense but overall yummy. My little one loved it as he loves peanut butter. The topping is Reese's peanut butter chips which Sister No.1 got for me when she went to the States. Yum!
