In a saucepan, combine the ingredients for the molasses layer. Cook and stir over medium heat until the mixture has thickened. This will take about 5-10 minutes, depending on your stove. Allow it to come to a low boil, but not a full boil. Allow the mixture to cool while you prepare the topping. 1/2 cup brown sugar, 1/2 cup molasses, 1 large egg, 1 1/2 cups water, 1 tablespoon all-purpose flour, 1 teaspoon vanilla extract
For the topping, combine the flour, brown sugar, melted butter and baking soda. Mix well. 1 cup all-purpose flour, 1/2 cup brown sugar, 1/4 cup salted butter, 1/2 teaspoon baking soda
Pour the molasses mixture into the unbaked pie shell. Sprinkle the crumbs on top of the molasses mixture. 1 unbaked 9" pie shell
Bake for 40-45 minutes until the top is golden brown and the center starts to puff up.
Allow the pie to cool before slicing. This is considered a "wet-bottom" pie, so when you slice it, the bottom may be slightly "wet" and that's exactly how it should be.
Notes
Sugar: Dark brown sugar gives the deepest flavor.Crumb topping add-in: Stir ½ teaspoon of cinnamon into the crumb topping mixture. It adds warmth without overpowering the molasses.Wet bottom is normal: This pie will always have a gooey, slightly syrupy bottom layer. It's supposed to. Don't overbake.Storage: Room temperature, loosely covered, up to 2 days. Refrigerate up to 5 days. Freeze individual slices wrapped tightly for up to 2 months.Refer to the article above for more tips and tricks.The calories shown are based on the pie being cut into 8 pieces, with 1 serving being 1 slice of pie.
