Crust and Topping Ingredients

  • 3 cups all-purpose flour
  • 1 cup butter, cut into pieces
  • 1 cup granulated white sugar
  • 1/2 teaspoon salt
  • 1 teaspoon baking powder
  • 1 large egg

Blackberry Filling Ingredients

  • 4 cups blackberries
  • 1 tablespoon fresh lemon juice
  • 1 tablespoon cornstarch
  • 3/4 cup granulated white sugar


  • Preheat oven to 375 F. Grease a 9 x 13 inch baking pan. Stir together the flour, 1 cup white sugar, baking powder, and salt. Cut in the butter, until the butter is in pea-sized pieces. (See note below for an easy tip!)
  • Stir in the beaten egg with a fork. Press half of the dough into the bottom of the baking dish. Combine the blackberries, lemon juice, cornstarch, and sugar in a medium-size mixing bowl and stir to combine.
  • Scatter the sugared berries over the crust in the pan. Sprinkle with the other half of the dough mixture.
  • Bake at 375 F for 30-35 minutes, or until lightly browned. Let cool completely.


To "cut in the butter" means working large chunks of butter into dry ingredients (usually flour) in order to break the butter down into smaller pieces that are each fully coated in those dry ingredients. You can even grate the cold butter straight into the flour! Use butter straight from the refrigerator, don’t let it warm on the counter while you set up the grater. It takes only 15-20 seconds to grate a cold stick of butter. Toss the fluffy grated butter into flour to lightly coat it and then all you need is a fork or your fingers to turn it into perfect crumbs in moments.
