Chocolate Whoopie Pies with Caramel Cream Cheese Buttercream Frosting

As I stated at the end of my chocolate macarons recipe post, I had a ton of caramel cream cheese frosting left over. So after a while of it sitting in my fridge. I decided to make chocolate whoopie pies and use the frosting as the filling. It didn't take me long to find a recipe: a while ago I bought a whoopie pie recipe book at Barnes & Noble. So I pulled it from my (barely used) recipe bookshelf and found a recipe for chocolate whoopie pies (not hard to find as it was the first one. Based on the recent Portland, Maine, episode of the Food Network show I Hart Food, chocolate with marshmallow filling is the original whoopie pie flavor). I mainly chose whoopie pies because a few years ago I got a whoopie pie pan at Kohl's and I've only used it once. Plus, these things are pretty easy to make.
