Whoopie pie

A whoopie pie is a cake sandwich made with two small chocolate cakes in the shape of buns and a creamy filling in between them. It is similar to the Drake's Devil Dog snack cake.

In the EMPATH: The Luckiest Smurf story series, Biscotti and Gelato make a similar kind of cake for their fellow Smurfs to enjoy as either desserts served with smurf cream or as snack items by themselves.
