Ingredients
Method
- Step 1: Prepare the Crust
Preheat oven to 160°C (325°F). Crush the digestive or graham crackers into fine crumbs. Mix with granulated sugar and melted butter until evenly combined. Press the mixture firmly into the bottom of a greased 9-inch springform pan. Bake for 10 minutes, then cool while preparing the filling. - Step 2: Make the Blueberry Mixture
In a bowl, toss fresh blueberries with sugar, flour, and lemon juice. Set aside. - Step 3: Prepare the Crumble Topping
Combine flour, dark brown sugar, and butter. Mix with your fingers or a fork until crumbly and coarse. Refrigerate until ready to use. - Step 4: Make the Cheesecake Batter
In a large bowl, beat cream cheese and sugar until smooth and creamy. Add sour cream, cornstarch, and vanilla extract. Beat in the eggs one at a time, mixing just until combined after each addition. - Step 5: Assemble
Pour cheesecake batter over the cooled crust. Evenly distribute the prepared blueberries over the top, then sprinkle the crumble mixture across the surface. - Step 6: Bake
Place the springform pan in a roasting pan and add hot water halfway up the sides to create a water bath. Bake for 1 hour 20–30 minutes, or until the center is slightly wobbly but mostly set. Turn off the oven, crack the door, and let it cool inside for 1 hour. - Step 7: Chill and Serve
Remove from the water bath, cool to room temperature, then refrigerate for at least 4 hours or overnight before slicing and serving.
Notes
For extra flavor, add a hint of lemon zest to the cheesecake batter. You can also replace fresh blueberries with frozen ones — no need to thaw first. Store leftovers covered in the refrigerator for up to 5 days.
