Ingredients
Scale
- 3 cups all-purpose flour
- 1 cup granulated sugar
- 1 teaspoon baking powder
- ½ teaspoon fine sea salt
- 2 teaspoons lemon zest
- 1 cup unsalted butter (cold, cut into pieces)
- 1 large egg
- 1 teaspoon pure vanilla extract
- 4 cups fresh or frozen blueberries
- ½ cup granulated sugar
- 1 tablespoon cornstarch
Instructions
- Preheat the oven to 375°F and prepare a 9×13-inch baking pan with cooking spray and parchment paper.
- In a food processor, combine flour, sugar, baking powder, salt, and lemon zest, pulsing to mix.
- Add cold butter pieces to the flour mixture and pulse until it resembles coarse meal with some pea-sized butter pieces.
- Whisk together egg and vanilla in a small bowl, then stream into the food processor, letting it run briefly until combined into a crumbly dough.
- Press just over half of the dough mixture into the bottom of the prepared pan and bake for 10 minutes until golden around the edges.
- In a bowl, combine blueberries, sugar, and cornstarch, then evenly spread over the baked crust.
- Crumble the remaining dough over the blueberries, squeezing it for larger crumbs.
- Bake for 35-40 minutes until the top is golden and bubbly; let cool completely before cutting into squares.
Notes
For optimal flavor, use fresh lemons for the zest.
You can substitute frozen blueberries if fresh ones are unavailable, no adjustments needed.
