Chocolate Peanut Butter Cupcakes with Fudgy Centers

This flavor combination has been a long time coming.  Peanut butter is one of my absolute favorite things.  When I was a child, I remember eating peanut butter sandwiches for lunch everyday at school on my Papa's homemade bread.  Sometimes I ate jelly sandwiches, but never peanut butter and jelly together.  I know, I'm some kind of freak of nature that doesn't like peanut butter and jelly sandwiches, but it just never made much sense to me.  Plus peanut butter is completely delicious on its own, so why add jelly?  Chocolate and peanut butter . . . now that's a different story.  Those are two that belong together - a match made in heavy!  These cupcakes have a delicious fudgy center that add something special to its overall texture.  And the frosting, don't even get me started on that.  I'm lucky I had enough to frost the cupcakes.  Enjoy!
