For Chuckie's birthday kegger, I made a million (well, 72, minus the 7 or so I accidentally flipped onto the bottom of the oven) bite-sized chocolate cupcakes with peanut butter frosting. Tasty!
I doubled-down on this easy chocolate cupcake recipe, and made 2 times Ina Garten's PB frosting recipe. Since I was using the mini-muffin tins, I sprayed the tins rather than use paper liners, and I cooked the cupcakes for 10 minutes.
