There a few things I would do differently the second time I make them. The peanut butter center came out a bit dry for me as did the chocolate cake part (this could be from overworking the batter which I tend to do sometimes and am trying to learn from). The recipe says it yields 24 cupcakes but I got only about 16 or so cupcakes out of it which could also amount to why I had soo much icing left over.
I found this recipe here.
