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 of sugar, baking powder, and salt.
  3. Cut in the cold butter until the mixture resembles coarse crumbs.
  4. Mix in the beaten egg and vanilla until the dough begins to clump together.
  5. Reserve about 1/3 of the dough for topping and press the remaining into the bottom of the pan.
  6. Place the crust in the freezer for about 10 minutes.
Filling
  1. In another bowl, gently toss blueberries with 1/2 cup sugar, cornstarch, lemon juice, and lemon zest.
  2. Once the crust has chilled, spread the blueberry mixture evenly over the crust.
  3. Crumble the reserved dough over the blueberry layer.
Baking
  1. Bake for 45 to 50 minutes or until the topping is golden brown and the filling is bubbling.
  2. Remove from the oven and allow to cool completely before cutting.

Notes

Use fresh blueberries for the best flavor or substitute with frozen ones if necessary. To maintain a crisp topping, avoid overmixing when adding the egg and vanilla.
