Ingredients

Crust and Topping

3 cups all purpose flour spooned and leveled
1 cup unsalted butter 2 sticks, cut into small pieces
1 cup granulated sugar
2 teaspoons lemon zest zest of one lemon
1 teaspoon vanilla extract
½ teaspoon fine sea salt
1 teaspoon baking powder
2 large eggs room temperature, whisked

Blackberry Filling

4 cups blackberries fresh or frozen
1 tablespoon lemon juice
1 tablespoon cornstarch
¾ cup granulated sugar

Instructions

Preheat oven to 375°F. Grease a 9"x 13" baking pan, or line with parchment paper.
In a large bowl, add all crust ingredients except eggs. (Be sure the butter has been cut into small chunks ahead of time.)
3 cups all purpose flour, 1 cup unsalted butter, 1 cup granulated sugar, 2 teaspoons lemon zest, 1 teaspoon vanilla extract, ½ teaspoon fine sea salt, 1 teaspoon baking powder
Use a pastry blender to combine the ingredients until all of the butter is well incorporated, and no pieces are larger than a pea. (This could also be done using a food processor, using short pulses.) Stir in the beaten eggs.
2 large eggs
Pour half of the crust (crumb) mixture into the bottom of the prepared pan. Use a spatula to press into a solid crust, set aside remaining bowl of crumble.
Prepare the filling by combining all filling ingredients into a bowl and stirring just until the berries are fully coated. Pour berries over the prepared crust, spreading into a single layer.
4 cups blackberries, 1 tablespoon lemon juice, 1 tablespoon cornstarch, ¾ cup granulated sugar
Sprinkle the remaining crumble mixture over the berries, distributing evenly.
Bake at 375°F for 35-45 minutes, or until bubbly and light golden brown. Cool before cutting into bars. Store bars in a sealed container in the refrigerator.
