Creating Blueberry Crumble Cheesecake can be straightforward if you follow these simple steps:

1. Preheat Oven: Preheat your oven to 325°F (160°C) and grease a 9-inch springform pan.
2. Make the Crust: In a bowl, combine graham cracker crumbs, melted butter, and sugar. Press the mixture firmly into the bottom of the prepared pan.
3. Prepare the Filling: In a large mixing bowl, beat softened cream cheese until smooth. Gradually add sugar and mix until creamy. Add vanilla extract and mix well.
4. Add Eggs: Beat in the eggs, one at a time, mixing just until combined. Do not overmix.
5. Incorporate Sour Cream: Fold in the sour cream until well combined, ensuring the mixture is smooth.
6. Add Blueberries: Gently fold in the fresh blueberries, distributing them evenly throughout the filling.
7. Pour Filling: Pour the cheesecake filling over the crust in the springform pan, smoothing the top with a spatula.
8. Prepare the Crumble: In a separate bowl, mix flour, brown sugar, rolled oats, softened butter, and cinnamon until crumbly.
9. Add Crumble Topping: Evenly sprinkle the crumble topping over the cheesecake filling.
10. Bake: Place the cheesecake in the preheated oven and bake for 50-60 minutes, or until the center is set but still slightly jiggly.
11. Cool Down: Turn off the oven and leave the cheesecake inside for an additional hour. Then, remove it and let it cool to room temperature.
12. Chill: Once cooled, refrigerate the cheesecake for at least 4 hours or overnight for best results.
