Making Blueberry Crumble Cheesecake is straightforward if you follow these steps closely:

1. Preheat Your Oven: Set your oven to 325°F (160°C) and prepare a 9-inch springform pan by greasing it lightly.
2. Prepare the Crust: In a large bowl, mix together the flour, oats, brown sugar, cinnamon, and salt. Stir in the melted butter until the mixture is crumbly. Set aside.
3. Make the Cheesecake Filling: In a mixing bowl, beat the softened cream cheese using an electric mixer until smooth. Gradually add granulated sugar and continue beating until combined.
4. Add Vanilla and Eggs: Add the vanilla extract and then the eggs one at a time, mixing just until incorporated. Do not overmix.
5. Fold in Blueberries: Gently fold in the fresh blueberries, taking care not to break them.
6. Assemble the Cheesecake: Pour the cheesecake filling into the prepared springform pan. Spread it evenly.
7. Add the Crumble Topping: Sprinkle the crumble mixture generously over the cheesecake filling, covering it completely.
8. Bake: Place the cheesecake in the preheated oven and bake for 45-50 minutes or until the center is set and the top is lightly golden.
9. Cool: Once baked, turn off the oven and leave the cheesecake inside with the door slightly ajar for about 30 minutes. This helps prevent cracking.
10. Chill: Carefully remove the cheesecake from the oven and allow it to cool to room temperature. Then, transfer it to the refrigerator to chill for at least 3 hours before serving.

Following these steps will ensure that your Blueberry Crumble Cheesecake turns out perfectly every time!
