what you'll need


  • 4 cups blackberries
  • 1/3 cup granulated sugar
  • 2 Tbsp lemon juice
  • 1/2 zest of lemon
  • 1 pinch salt


  • 2 1/4 cups all-purpose flour
  • 3/4 tsp baking powder
  • 1/2 tsp salt
  • 1 cup unsalted butter cold and diced into cubes
  • 3/4 cup granulated sugar
  • 1 large egg well-beaten
  • 2 tsp vanilla extract

let's do it

  • Place rack in center of the oven then preheat to 350 degrees. Coat a 13" x 9" cake pan with cooking spray or line with parchment paper then set aside.
  • In a medium-sized mixing bowl, toss blackberries with sugar, lemon juice and lemon zest until well combined then set aside.
  • In a separate large mixing bowl, sift together flour, baking powder and salt. Cut the cold butter into flour mixture using a pastry cutter or fork until the mixture resembles coarse crumbs, then add ¾ cup granulated sugar and stir until combined.
  • In a small bowl, whisk together the beaten egg and vanilla then add to dry ingredients. Mix until well combined—the mixture will be dry and shaggy-looking.
  • Transfer 3 cups of the pastry mixture to the bottom of the prepared pan then press into an even layer. Pour blackberry filling—including juices—over the crust then spread into an even layer.
  • Crumble remaining pastry mixture evenly over the top of blackberries then bake 40–45 minutes until the top becomes a light golden brown. Remove from oven then allow to cool until crust becomes firm. Serve slightly warm, or at room temperature. Enjoy!
