Blueberry Crumble Bars
Cook time
Total time
Serves: 16 large bars
  • 1 cup white sugar
  • 1 teaspoon baking powder
  • 3 cups all-purpose flour
  • 1 cup cold butter (2 sticks or 8 ounces), cubed
  • 1 egg
  • ¼ teaspoon salt
  • Zest and juice of one lemon
  • 4 cups fresh or frozen blueberries (if using frozen, be sure to drain them!)
  • ⅓ cup white sugar
  • 4 teaspoons cornstarch
  1. Preheat the oven to 375 degrees F (190 degrees C). Grease and/or line a 9×13 inch pan (I highly suggest lining your pan with tinfoil and then spraying it with a bit of Pam for easy removal).
  2. In a medium bowl, stir together 1 cup sugar, 3 cups flour, and baking powder. Mix in the salt and lemon zest.
  3. Use a fork or pastry cutter to blend in the butter and egg (I used my hands and found it to be much easier). Dough will be crumbly. Pat half of dough into the prepared pan.
  4. In another bowl, stir together the sugar, cornstarch and lemon juice. Gently mix in the blueberries.
  5. Sprinkle the blueberry mixture evenly over the crust. Crumble remaining dough over the berry layer.
  6. Bake in preheated oven for 45 minutes, or until top is slightly brown (mine were absolutely perfect at 45 minutes, but check them at about 40 minutes to make sure they aren't burning!). Cool completely before cutting into squares (I chilled mine in the fridge for a bit). Makes 16 large bars.
