Prep Time15 mins

Total Time3 hrs
Servings: 18 bars


  • 1 1/2 cups sugar divided
  • 1 teaspoon baking powder
  • 3 cups all-purpose flour
  • 2 sticks butter unsalted, cold
  • 1 egg
  • 1/4 teaspoon salt
  • 1 lemon zested and juiced
  • 4 cups fresh blueberries
  • 4 teaspoons cornstarch


  • Preheat the oven to 375 degrees F (190 degrees C). Grease a 9×13 inch pan and line with parchment paper.
  • In a medium bowl, stir together 1 cup sugar, 3 cups flour, and baking powder. Mix in salt and lemon zest. Use a fork or pastry cutter to blend in the butter and egg. Dough will be crumbly. Pat half of dough into the prepared pan.
  • In another bowl, stir together the sugar, cornstarch and lemon juice. Gently mix in the blueberries. Sprinkle the blueberry mixture evenly over the crust. Crumble remaining dough over the berry layer.
  • Bake in preheated oven for 45 minutes, or until top is slightly brown. (This took an extra 10 to 15 minutes in my oven.) Cool completely before cutting into squares.
