1. Prepare the Crust

1. Preheat oven to 325°F (163°C). Grease a 9-inch springform pan.
2. In a bowl, mix graham cracker crumbs, sugar, and melted butter until combined.
3. Press the mixture firmly into the bottom of the pan, creating an even layer.
4. Bake for 8-10 minutes, then let cool while preparing the filling.

2. Make the Cheesecake Batter

5. In a large bowl, beat cream cheese and sugar until smooth and creamy.
6. Add sour cream and vanilla extract, mixing until fully incorporated.
7. Beat in eggs one at a time, mixing just until combined (avoid overmixing to prevent cracks).

3. Create the Midnight Blueberry Swirl

8. In a saucepan over medium heat, combine blueberries, sugar, and lemon juice.
9. Cook, stirring occasionally, until blueberries break down and release their juices.
10. Mix cornstarch with water to create a slurry, then stir into the blueberry mixture.
11. Simmer for 2-3 minutes until thickened, then remove from heat and let cool.

4. Assemble & Bake the Cheesecake

12. Pour the cheesecake batter over the cooled crust, smoothing the top.
13. Spoon dollops of blueberry swirl over the batter and use a skewer or knife to create midnight-inspired swirls.
14. Bake for 50-60 minutes, or until the center is slightly jiggly but set.
15. Turn off the oven and let the cheesecake cool inside for 1 hour before transferring to the fridge to chill for at least 4 hours or overnight.

5. Decorate & Serve

16. Dust with edible silver glitter or sprinkles to create a starry, enchanted look.
17. Slice and serve your Ravenclaw Midnight Blueberry Cheesecake at Hogwarts feasts, book nights, or magical dessert tables!
