Step 1: Preheat your oven to 325°F (165°C). Lightly grease a 9-inch springform pan.

Step 2: Combine graham cracker crumbs, 2 tablespoons sugar, and melted butter in a bowl. Press into the bottom of the prepared pan.

Step 4: Pour the cream cheese mixture over the crust. Spread evenly.

Step 5: In another bowl, mix flour and brown sugar. Cut in cold cubed butter until the mixture resembles coarse crumbs.

Step 6: Sprinkle the crumble mixture evenly over the cheesecake filling.

Step 7: Gently scatter the fresh blueberries on top.

Step 8: Bake in preheated oven for about 60 minutes, or until the center is set.

Step 9: Allow the cheesecake to cool to room temperature, then refrigerate for at least 4 hours before serving.
