How to Make Blueberry Crumb Bars

  1. Preheat oven to 375°F (190°C).
  2. Butter a 13x9x2 inch metal baking pan.
  3. In a large bowl, whisk together 2 cups all-purpose flour, 1 cup rolled oats, ¾ cup granulated sugar, ½ teaspoon salt, and 1 teaspoon ground cinnamon.
  4. Cut in 1 cup (2 sticks) cold unsalted butter using a pastry blender or your fingers until the mixture resembles coarse crumbs.
  5. Transfer 2 cups of the crumb mixture to a medium bowl. Stir in ½ cup sliced almonds and set aside for topping.
  6. Press the remaining crumb mixture evenly into the bottom of the prepared pan.
  7. Bake the crust for 22-25 minutes, or until golden and just firm to the touch.
  8. Let cool for 10 minutes.
  9. In a medium bowl, gently combine 12 ounces fresh or frozen blueberries (do not thaw), ½ cup blueberry preserves, 1 tablespoon all-purpose flour, and 1 tablespoon lemon zest.
  10. Spread the blueberry mixture evenly over the cooled crust.
  11. Sprinkle the reserved almond crumb topping evenly over the filling.
  12. Bake for 35-40 minutes, or until the filling is bubbling thickly at the edges and the topping is golden brown.
  13. Let cool completely in the pan on a wire rack before cutting.
  14. Cut the cooled bars lengthwise into 4 strips, then cut each strip into 6 pieces, for a total of 24 bars.
