Peanut Butter Banana Whoopie Pies: Creamy Cookie & Cake in One

banana whoopie piesOnce upon a time, I considered the New York cheesecake to be the greatest of all desserts out of the northeast. Oh was I wrong. I have since discovered the one thing my life had always been missing: whoopie pies! Where have these sweet little sandwiches full of goodness been hiding all of my life?

It as is if the cream-filled cookie and the cake got married and made ... well I guess they made whoopie (sorry, sorry, I had to go there). They're cake and cookie, and the way these are made -- cakey outside, creamy inside -- makes for endless flavor combinations. But is there anything that can top banana whoopie pies with peanut butter filling? Mmm. Check this recipe out!
