Ingredients

The following ingredients have 4 Servings
  • 3 cups all-purpose flour
  • 1 cup granulated sugar
  • 1 teaspoon baking powder
  • 1/4 teaspoon salt
  • 1 cup (2 sticks) unsalted butter (cold, and cut into cubes)
  • 1 large egg
  • lemon zest (from 1 lemon)
  • 4 cups fresh blueberries
  • 1/2 cup granulated sugar
  • 4 teaspoons cornstarch
  • Juice of 1 lemon

Instruction

  • Preheat oven to 375F and grease or line a 9x13 baking pan. 
  • In a large bowl, whisk together the flour, sugar, baking powder, lemon zest and salt. Add the butter cubes and the egg and use the pastry cutter to blend until crumbly. Press half of the dough into the prepared pan (set aside the other half of the dough).
  • In a separate bowl, whisk the sugar, cornstarch, and lemon juice together. Add the blueberries, and stir until combined. Pour the blueberry mixture over the crust and top with the remaining mixture. 
  • Bake for 50 minutes, or until the top is a light golden brown. Allow the bars to cool completely on the cooling rack before cutting into squares. If you'd like, you can also stick the pan in the fridge for about 30 minutes; it's a little easier to cut into this way!
