Shoofly is a molasses pie that developed its traditional form among the Pennsylvania Dutch in the 1880s, who ate it with strong black coffee for breakfast. It is called Melassich Riwwelboi or Melassichriwwelkuche (molasses crumb cake) in the Pennsylvania Dutch language.
Shoofly pie is a molasses crumb cake baked in a pie crust. The primary ingredients of the filling are molasses, flour, brown sugar, egg, and water. The addition of a pie crust makes it easier for people to hold a piece in the hand while eating it.
It comes in two different versions: wet-bottom and dry-bottom. The dry-bottom version is baked until fully set and results in a more cake-like consistency throughout. The wet-bottom version is set like cake at the top where it was mixed in with the crumbs, but the very bottom is a stickier, gooier custard-like consistency.
