Shoofly pie
Shoofly pie is a molasses pie that is considered a delicacy in both Pennsylvania Dutch and Southern cooking. It is often referred to as "wet bottom" in its most common form because it comprises of a layer of sweet, gooey molasses beneath a crumb topping sometimes compared to that of a coffee cake. In contrast, a "dry bottom" shoofly pie is more thoroughly mixed into a cake-like consistancy.
The dessert has earned quite a reputation in the "Dutch Country" of Lancaster County, Pennsylvania, where its distinctive flavor and texture is quite alluring to tourists. The origin of the name is commonly thought to arise from the cooling of a fresh-made pie on a window sill during colonial times, where the scent would attract flies that would have to be "shooed" away.
