Shoofly pie — a single-crust pie with a filling of molasses, brown sugar, and water beneath a crumb topping of flour, brown sugar, and butter — is the Pennsylvania Dutch dessert most closely identified with the Lancaster County Amish and Mennonite communities. The name comes from the need to "shoo" away the flies attracted by the molasses (or from the *Shoo-Fly* brand of molasses, depending on the source). The pie exists in two forms: **wet-bottom** (the molasses filling remains gooey and custardy beneath the crumb) and **dry-bottom** (the crumb is distributed throughout, producing a more cake-like texture). The wet-bottom is the more traditional and the more interesting.
A single pie crust filled with a mixture of molasses (dark, full-flavoured — not blackstrap), brown sugar, boiling water, and baking soda (the soda reacts with the molasses's acid, producing carbon dioxide that lightens the filling). A crumb topping of flour, brown sugar, and butter (cut together into coarse crumbs) is sprinkled over the filling. During baking (175°C, 35-40 minutes), the crumb partially sinks into the filling while some remains on top, creating a layered texture: gooey molasses bottom, cakey middle, crumbly top.
1) Wet-bottom: pour filling first, add crumb on top. The crumb sinks partially, creating layers. 2) Dark molasses is essential — light molasses is too mild. The mineral, bittersweet depth of dark molasses defines the pie. 3) The baking soda is structural — it lightens the dense molasses filling and creates the specific texture.
Shoofly pie with coffee — the bitterness of strong black coffee against the sweet, dark molasses is the Pennsylvania Dutch breakfast pairing. Yes, pie for breakfast is the Pennsylvania Dutch tradition, and shoofly pie specifically was designed as a breakfast food — the molasses and grain providing energy for farm work.
