So, tonight I finally quenched my craving by making Peanut Butter Cup-Cup Cakes, which were my own creation. Basically I made devils food cake bater, and while the cupcakes were baking I took them out and inserted a mini peanut butter cup in the batter. When the cakes were done, I frosted them w/ homemade peanut butter buttercream icing (make a regular buttercream and replace half of the butter with peanut butter). OMG THEY ARE SO GOOD!
That's all I have to say.
You should really make them. If you don't have peanut butter cups on hand, it might work just as well to add a small dollop of peanut butter in the middle of batter during baking. Tell me if it works.
