Prepare the Crumble Topping:
In a medium bowl, combine the all-purpose flour, granulated sugar, and ground cinnamon (if using).
Add the cold, cubed butter to the dry ingredients. Use a pastry cutter or your fingers to mix until the mixture resembles coarse crumbs.
Evenly sprinkle the crumble topping over the cheesecake filling.
Bake the Cheesecake:
Bake in the preheated oven for about 1 hour, or until the center is almost set but still slightly jiggly.
Turn off the oven and allow the cheesecake to cool inside with the door slightly open for about 1 hour.
Remove the cheesecake from the oven and refrigerate for at least 4 hours, or preferably overnight.
Serve:
Carefully remove the sides of the springform pan before serving.
