Instructions
2. Make the Filling:
In a large bowl, whisk together the molasses and hot water until combined. Stir in the baking soda and salt—the mixture may foam up slightly, which is normal. Allow it to cool for about 5 minutes so it’s no longer scalding hot. While whisking continuously, slowly pour in the beaten egg until fully incorporated. Pour the finished filling into the cooled pie crust.
3. Make the Crumb Topping:
In a separate bowl, whisk together the flour, packed brown sugar, and cinnamon. Add the cold butter pieces and use a pastry cutter, two forks, or your fingers to cut the butter into the dry ingredients until the mixture resembles coarse pebbles or sand.
4. Assemble the Pie:
Sprinkle the crumb topping evenly over the molasses filling, covering its entire surface. It’s fine if you can no longer see the filling.
5. Bake:
Place the pie on the center oven rack and bake at 400°F for 15 minutes. Then, without opening the oven door, reduce the heat to 350°F (175°C). Continue baking for another 25-30 minutes, or until the filling is set and the topping is golden brown.
6. Cool and Serve:
Remove the pie from the oven and allow it to cool completely on a wire rack before slicing. This allows the filling to set fully for clean slices.
