  • 1 teaspoon baking powder
  • 1/2 teaspoon salt
  • 1 cup cold unsalted butter, cubed Keep the butter cold for a flaky crust.

Method
 

Preparation
  1. Preheat your oven to 375°F (190°C) and line a 9x13-inch baking pan with parchment paper.
  2. In a large bowl, whisk together the flour, 1 cup sugar, baking powder, and salt until well blended.
  3. Add the cold, cubed butter and mix until it resembles coarse crumbs.
  4. Stir in the beaten egg and vanilla extract until the dough begins to clump together.
  5. Press about two-thirds of the dough firmly into the bottom of the prepared pan to form the crust and place in the freezer.
Filling
  1. In a separate bowl, combine the fresh blueberries, 1/2 cup sugar, cornstarch, lemon juice, and lemon zest. Toss gently.
  2. Spread the blueberry mixture evenly over the crust.
  3. Crumble the remaining dough over the blueberry layer.
Baking
  1. Bake in the preheated oven for 45 to 50 minutes, until the top is golden brown and the filling is bubbling.
  2. Allow to cool completely in the pan before lifting out and cutting into squares.

Notes

For best results, avoid over-mixing the dough and handle it as little as possible. Serve with powdered sugar or vanilla ice cream for an extra touch.
