A Whoopie Pie is a popular dessert that consists of two soft, cake-like cookies sandwiching a creamy filling. Traditionally, the cookies are made from chocolate or vanilla cake batter, while the filling is often a sweet marshmallow or buttercream mixture. This treat is especially popular in the northeastern United States. The origins of the Whoopie Pie are debated, with claims from both Maine and Pennsylvania as its birthplace. It is often enjoyed at fairs, bakeries, and home gatherings, making it a beloved comfort food for many. Variations exist, with different flavors and fillings, but the classic version remains a favorite.
