Ingredients

Scale
  • 1 ½ cups graham cracker crumbs (about 10 full sheets, crushed finely)
  • ⅓ cup granulated sugar
  • 6 tablespoons unsalted butter, melted
  • Pinch of salt
  • 16 oz (450 g) cream cheese, softened
  • ⅔ cup granulated sugar
  • 2 large eggs, room temperature
  • 1 teaspoon vanilla extract
  • ½ cup sour cream
  • 1 cup fresh or frozen blueberries (if frozen, thaw and drain excess liquid)
  • 2 tablespoons granulated sugar
  • 1 teaspoon lemon juice
  • 1 teaspoon cornstarch mixed with 1 tablespoon water (optional)

Instructions

  1. Preheat oven to 325°F (163°C). In a medium bowl, combine graham cracker crumbs, sugar, melted butter, and salt. Stir until mixture feels like wet sand and holds together when pressed. Press firmly and evenly into bottom of 9×9 inch pan. Bake for 10 minutes, then remove and let cool.
  2. In a small saucepan over medium heat, combine blueberries, sugar, and lemon juice. Simmer gently for about 5 minutes, stirring occasionally until berries break down. If sauce is too thin, stir in cornstarch slurry and cook 1-2 minutes until thickened. Remove from heat and let cool slightly.
  3. In a large bowl, beat softened cream cheese with sugar until smooth and creamy. Add eggs one at a time, mixing well after each. Stir in vanilla extract and sour cream until combined. Avoid overmixing.
  4. Pour cheesecake filling over cooled crust and spread evenly. Drop spoonfuls of blueberry sauce over batter. Use toothpick or skewer to gently swirl sauce, creating marbled effect without over-swirl.
  5. Bake at 325°F (163°C) for 35-40 minutes until edges are set but center jiggles slightly. Turn off oven and leave door slightly ajar for 15 minutes to cool gently.
  6. Remove bars from oven and cool completely at room temperature. Refrigerate at least 4 hours or overnight before slicing.
  7. Use a sharp knife dipped in hot water and wiped dry between cuts for clean edges. Serve chilled or at room temperature, optionally garnished with fresh blueberries or whipped cream.

Notes

Use room temperature cream cheese and eggs to avoid lumps and cracking. Swirl blueberry sauce gently with a toothpick to preserve distinct colors. Avoid overbaking to prevent dryness and cracks. Cool bars gradually with oven door ajar before refrigerating. For gluten-free crust, substitute graham cracker crumbs with almond flour or gluten-free cookie crumbs. Vegan adaptations include vegan cream cheese, coconut yogurt, and flax egg.
