Ingredients
Method
Make the Crust
- Preheat oven to 325°F (165°C). Mix graham cracker crumbs, sugar, and melted butter until combined. Press firmly into the bottom of a 9-inch springform pan. Bake for 10 minutes. Let cool.
Prepare the Cheesecake Filling
- Beat cream cheese and sugar until smooth. Add eggs one at a time, mixing gently. Mix in vanilla, sour cream, and flour until just combined. Pour filling over cooled crust and smooth the top.
Make the Blueberry Layer
- In a bowl, toss blueberries with sugar, cornstarch, and lemon juice. Spoon evenly over the cheesecake batter.
Make the Crumble
- Combine flour, oats, brown sugar, and cinnamon. Cut in cold butter until crumbly. Sprinkle evenly over blueberries.
Bake
- Bake for 50–55 minutes, until the center is just slightly jiggly. Turn off oven, crack the door, and let cheesecake cool inside for 1 hour.
Chill
- Refrigerate at least 3 hours (overnight is best) before slicing.
Notes
No cracks: Avoid overmixing and let the cheesecake cool slowly.
Frozen blueberries: Use straight from frozen—no need to thaw.
Extra flavor: Add lemon zest to the filling for brightness.
Clean slices: Wipe knife between cuts.
