Cook Time 40 minutes
Total Time 50 minutes
Servings 1 8 x 8 inch square pan


Crust and crumble

  • 2 cups flour
  • 1/2 cup sugar
  • 1/2 tsb baking powder
  • 1/4 tsp salt
  • 8 tbs diced butter, chilled
  • 1 egg, room temperature


  • 12 oz blackberries
  • 1 tbs fresh lemon juice
  • 1/4 cup sugar


  • Preheat the oven to 350 F and prepare an 8 x 8 baking dish by lightly greasing or lining with parchment paper.
  • Stir together the flour, sugar, baking powder, and salt. Cut in the butter with a pastry blender or fork until evenly incorporated and the butter is in crumbs roughly the size of peas.
  • Beat the egg separately, then stir into the flour mixture with a fork.
  • Press about 1/2 to 3/4 of the mixture into the bottom of the baking dish.
  • Cut the blackberries in half, then toss them in the lemon juice. Add the sugar and toss again to coat. Sprinkle them over the crust in the pan.
  • Sprinkle the remaining dough mixture over the blackberries.
  • Bake until it just about passes the toothpick test (a few moist crumbs are good to have around), about 40 minutes. Let cool completely in pan before cutting.
  • The bars can keep at room temperature in an airtight container for about 3 days. You can refrigerate them to keep them longer, but it'll change the texture.
