Ingredients

  • 1 cup white granulated sugar
  • 1 teaspoon baking powder
  • 3 cups all-purpose flour
  • 1 cup cold unsalted butter (2 sticks), cut into small cubes
  • 1 large egg
  • 1/2 teaspoon salt
  • Zest of 2 lemons
  • Juice of 2 lemons
  • 5 cups fresh or frozen blueberries
  • 1/2 cup white granulated sugar (for filling)
  • 4 teaspoons cornstarch

Instructions

  1. Preheat oven to 375°F (190°C). Grease a 9×13-inch baking pan and line with parchment paper.
  2. In a large bowl, combine 3 cups flour, 1 cup sugar, baking powder, salt, and lemon zest.

  4. Press half the crumb mixture into the bottom of the prepared pan.
  5. In a separate bowl, combine 1/2 cup sugar, cornstarch, and lemon juice. Fold in blueberries until coated.
  6. Spread the blueberry mixture evenly over the crust.
  7. Sprinkle remaining crumb mixture over the blueberry layer.
  8. Bake 45 minutes until top is lightly golden and filling bubbles.
  9. Cool completely in the pan. Refrigerate 2–3 hours for clean slicing, then cut into 16 bars.

Notes

  • Mixed Berry Version: Substitute half the blueberries with raspberries or blackberries.
  • Whole Wheat Blend: Replace 1 cup flour with whole wheat flour.
  • Almond Twist: Replace 1/2 cup flour with almond flour for a softer crumble.
  • Extra Lemon Flavor: Add 1/2 teaspoon lemon extract to the filling.
  • Glazed Bars: Drizzle a powdered sugar and lemon juice glaze over cooled bars.
  • Store bars in an airtight container in the refrigerator up to 5 days; freeze up to 3 months.
  • Reheat individual bars in the microwave 10–15 seconds if desired.
