Preheat the oven to 425 degrees Fahrenheit. Make sure your pie crust is in a pie dish ready to go and set it aside.
In a bowl, combine the all-purpose flour, 1 Tablespoon brown sugar, ground ginger, and allspice. Add in the butter and mix together with a pastry blender until the butter has broken down and the mixture takes on the appearance of coarse meal. Set aside.
Take another bowl and mix together the hot water, molasses, chocolate pudding, ¾ cup brown sugar, vanilla extract, and baking soda until everything is combined. Whisk in the egg and then pour into the pie crust.
Carefully sprinkle the crumble mixture on top of the molasses layer and then place in the oven.
Bake in the oven for 15 minutes.
Lower the temperature to 350 degrees Fahrenheit and bake for another 30 minutes.
Remove from the oven and let cool before serving.
Plate and enjoy!
Instead of using the pastry cutter, you can also place your flour, seasonings, and butter into a food processor and pulse until all of the ingredients are incorporated and the butter has been broken down to pea size.
Allow your shoofly pie to cool completely before cutting and serving. The pie filling will be very oozy when it is still warm.
