1 nine-inch pie crust
1 cup molasses
3/4 cup hot water
3/4 tsp baking soda
1 egg, beaten
1 1/2 cups all-purpose flour
3/4 cup packed brown sugar
4 tbsp butter
Preheat oven to 400°F. Whisk together molasses, hot water, and baking soda. Whisk in the beaten egg. Pour into pie crust. In a food processor, pulse together the flour, brown sugar, and butter, until the mixture looks like sand. Spread evenly over the molasses mixture. Bake at 400°F for 15 minutes. Lower oven temp to 350°F, and bake another 30 minutes. Allow to cool completely. Seriously, practice some delayed gratification, or your filling will ooze out all over the place.
I hope your Thanksgiving was filled with yummy food and gooey sweet treats!
