Crust and Topping

  • 3 cups flour
  • 1 cup butter 2 sticks, cut into small pieces
  • 1 cup sugar
  • 2 teaspoons fresh lemon zest zest of one lemon
  • 1 teaspoon vanilla extract
  • 1/2 teaspoon salt
  • 1 teaspoon baking powder
  • 2 eggs whisked with a fork

Blackberry Filling

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


  • Preheat oven to 375°F.  Grease a 9"x 13" baking pan, or line with parchment paper.
  • In a large bowl, add all crust ingredient except eggs.  Be sure the butter has been cut into small chunks ahead of time.
  • 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 egg.
  • 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.
  • 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.
