Shoofly-Pie

Shoofly pie (or shoo-fly pie) is a molasses pie considered traditional among the Pennsylvania Dutch and also known in Southern cooking.
The more common version of the recipe — sometimes referred to as "wet bottom" — consists 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 consistency.
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 term "shoo-fly pie" first appeared in print in 1926. The name is commonly thought to arise from the fact that the molasses in the pie is so attractive to flies that they have to be constantly "shooed" away.
A Montgomery pie is similar to a shoofly pie though lemon juice is usually added to the bottom layer and buttermilk to the topping. A chess pie is also similar, though unlayered and made with corn syrup.
