Instructions: Preheat Oven: Preheat your oven to 325°F (160°C). Grease a 9-inch springform pan and set it aside.
Make Crust: In a medium bowl, combine gingersnap cookie crumbs, 1/4 cup granulated sugar, and melted butter.
Bake Crust: Bake the crust in the preheated oven for 10 minutes. Remove from the oven and let it cool while you prepare the filling.
Prepare Filling: In a large bowl, beat the cream cheese until smooth. Add brown sugar and sour cream, and beat until well combined.
Bake: Place the pan in the oven and bake for 50-55 minutes, or until the edges are set but the center still jiggles slightly when shaken.
Serve: Before serving, remove the pie cake from the springform pan and transfer it to a serving platter.
