Ingredients

  • 1 cup all-purpose flour (for crust and topping)
  • 3/4 cup brown sugar (for crust and topping)
  • 3/4 cup oats (quick or rolled)
  • 1 tsp cinnamon
  • 1/4 tsp salt
  • 1/2 cup melted butter
  • 16 oz cream cheese, softened
  • 2/3 cup granulated sugar
  • 2 large eggs
  • 1/2 cup sour cream or Greek yogurt
  • 1 tsp vanilla extract
  • 1 tbsp lemon juice
  • 2 tbsp all-purpose flour (for filling)
  • 1 1/2 cups blueberries (fresh or frozen)
  • 2 tbsp granulated sugar (for blueberries)
  • 1 tsp lemon juice (for blueberries)
  • 1 tbsp flour or cornstarch (to thicken blueberry layer)

Instructions

  1. Preheat oven to 325°F (165°C). Grease a 9-inch springform pan.
  2. In a bowl, mix 1 cup flour, brown sugar, oats, cinnamon, salt, and melted butter until crumbly.
  3. Press about 2/3 of the crumble mixture into the bottom of the pan to form the crust. Reserve the rest for the topping.
  4. Bake the crust for 10 minutes, then set aside to cool slightly.
  5. In a large bowl, beat cream cheese until smooth. Add sugar, then eggs one at a time, beating well after each. Mix in sour cream, vanilla, lemon juice, and 2 tbsp flour until combined.
  6. Pour the cheesecake filling over the pre-baked crust and spread evenly.
  7. In a separate bowl, toss blueberries with 2 tbsp sugar, 1 tsp lemon juice, and 1 tbsp flour or cornstarch. Evenly sprinkle over the cheesecake filling.
  8. Sprinkle the reserved crumble mixture over the blueberries.
  9. Bake for 50–60 minutes, until the edges are set but the center still jiggles slightly.
  10. Cool completely at room temperature, then chill in the refrigerator for at least 4 hours before serving.

Notes

  • Use frozen blueberries straight from the freezer if fresh aren’t available.
  • Add chopped nuts to the crumble for extra texture.
  • Skip the bottom crust and use crumble only for a rustic look.
  • Swirl blueberry sauce into the filling for a marbled effect.
  • Freezes well—slice and wrap pieces individually.
