A Whoopie Pie is a traditional southern dessert that consists of two cake-like “cookies” sandwiched together with marshmallow filling. To make the cupcake equivalent of this simple, yet delectable dessert, start off with a chocolate cupcake. The cupcake should be have a springy, moist texture in order to perfectly echo the Whoopie Pie. After that cupcakes are baked, slice out a small core in each and fill them with homemade marshmallow filling. Top with chocolate frosting and enjoy!
