Chocolate Cupcakes with Peanut Butter Frosting

These cupcakes were for my friend Erin's birthday. She's a big fan of peanut butter, so it seemed to make sense. It might have made a little too much sense though...her roommate made her a chocolate cake with peanut butter frosting for her birthday... Oh well, both were delicious, and we sort of had a theme going.

I used my favorite chocolate cupcake recipe, which also happens to be the only chocolate cupcake recipe I've ever used. They turned out great. This is what I used for the frosting, though I had to use more milk and less sugar to get a nice consistency.
