Don't be fooled by these innocent looking treats. They're actually quite controversial.

Maine, Pennsylvania, New Hampshire and Massachusetts all claim to have invented the infamous whoopie pie, citing a bakery, market or cookbook where the first version of these cake-cookie hybrids originated. Conveniently, in every case it seems that the alleged bakery closed years ago, the markets died off and the cookbooks were lost in a fire. Others argue that the recipe's roots can be traced to Germany and were brought over by the Amish. It's a dessert with a past shrouded in mystery (which is pretty dramatic for a baked good with the word whoopie in its name).

I vote for less time spent arguing and more spent enjoying these tasty morsels: Two soft cake "cookies" with a rich, delicious filling sandwiched between them. Think of it as an upgraded cupcake with the perfect ratio of cake to frosting in each and every bite.
