Ingredients

Scale
  • 2 cups all-purpose flour
  • 1 cup old-fashioned rolled oats
  • 1 cup packed light brown sugar
  • 1 teaspoon baking powder
  • ½ teaspoon salt
  • 1 cup (2 sticks) cold unsalted butter, cubed
  • 16 ounces (2 blocks) full-fat cream cheese, softened
  • ½ cup granulated sugar
  • 1 large egg, room temperature
  • 2 teaspoons pure vanilla extract
  • 1 tablespoon all-purpose flour
  • 3 cups mixed berries (fresh or frozen)
  • ⅓ cup granulated sugar
  • 2 tablespoons cornstarch
  • 1 tablespoon lemon juice
  • 1 teaspoon lemon zest (optional)

Instructions

  1. Preheat oven to 350°F (175°C). Line a 9×13 inch baking pan with parchment paper, leaving an overhang on two sides.
  2. Make the crust and crumble: In a large bowl, whisk together 2 cups flour, oats, brown sugar, baking powder, and salt. Add cold cubed butter. Use a pastry cutter, fingers, or food processor to work butter into dry ingredients until mixture resembles coarse sand with some pea-sized clumps.
  3. Press about two-thirds of the crumble mixture firmly and evenly into the bottom of the prepared pan to form the crust.
  4. Prepare the berry layer: In a medium saucepan, combine mixed berries, ⅓ cup sugar, cornstarch, lemon juice, and zest. Cook over medium heat, stirring frequently, for 5-7 minutes until berries break down and mixture thickens into a jammy sauce. Remove from heat and let cool 10 minutes.
  5. Make the cheesecake filling: In a separate bowl, beat softened cream cheese and ½ cup granulated sugar until smooth and creamy. Beat in egg, vanilla extract, and 1 tablespoon flour until just combined.
  6. Assemble and bake: Spread cream cheese filling evenly over the crust. Gently spoon the cooled berry mixture over the cheesecake layer and spread carefully. Sprinkle the remaining third of the crumble mixture evenly over the top.
  7. Bake for 40-45 minutes, until crumble topping is golden brown and cheesecake layer is set at the edges (center may have a slight jiggle).
  8. Cool completely on a wire rack for at least 2 hours, then transfer to refrigerator to chill completely, about 2 more hours or overnight. Use parchment paper to lift the block from the pan before cutting into squares.

Notes

For clean slices, do not cut while warm. Ensure butter is cold for the crumble. Pre-cooking the berries prevents a soggy crust. Bars can be made ahead and freeze well for up to 3 months.
