This shoofly pie layers a molasses filling with warm-spiced buttery crumbs in a flaky pie crust. The filling bakes to a soft, custardy set and the flavors of cinnamon, ginger, and cloves deepen overnight, making it even better the second day.
Preheat the oven to 400°F. Line a pie dish with the single pie crust and set aside.
Combine the flour, nutmeg, ginger, cloves, cinnamon, salt, and brown sugar in a bowl. Cut in the cold butter with a pastry blender or fork until the mixture resembles coarse crumbs.
In a small bowl, dissolve the baking soda in the boiling water. Whisk in the molasses, then the egg yolk, until fully combined.
Layer the molasses filling and crumbs in alternating layers in the prepared crust, ending with a crumb layer on top. Three layers total is the target.
Bake for 10 minutes at 400°F, then reduce the oven temperature to 350°F and continue baking for about 20 minutes, until the filling feels like jello when pressed: firm but with a little give.
Cool completely at room temperature. Serve with whipped cream or vanilla ice cream.
Notes
Yield: One 9-inch pie, serves 12 slices. Doneness Cue: The filling should feel like jello when pressed lightly, firm but still yielding. It will firm further as it cools. Storage: Store at room temperature. The pie keeps well and the spice and molasses flavors intensify noticeably after the first day. Make Ahead: This pie is an excellent candidate for making one day ahead. The flavor improves overnight at room temperature.Adapted from Molly O'Neil's *One Big Table*
