Ingredients

Scale
  • 2 ½ cups all-purpose flour (about 312g), sifted
  • ¾ cup granulated sugar (150g)
  • ⅓ cup light brown sugar (70g), packed
  • 1 cup unsalted butter (226g), cold and cut into cubes
  • ½ teaspoon salt
  • 1 teaspoon ground cinnamon (optional)
  • 4 cups mixed berries (about 600g), fresh or frozen (blueberries, raspberries, blackberries)
  • ⅓ cup granulated sugar (65g)
  • 2 tablespoons cornstarch
  • 1 tablespoon fresh lemon juice
  • 1 teaspoon lemon zest (optional)

Instructions

  1. Preheat your oven to 350°F (175°C) and lightly grease a 9×13 inch baking pan.
  2. In a large mixing bowl, whisk together the flour, granulated sugar, brown sugar, salt, and cinnamon (if using).
  3. Add the cold, cubed unsalted butter. Using a pastry cutter or two forks, cut the butter into the flour mixture until it resembles coarse crumbs with some pea-sized pieces, about 3-4 minutes. Do not overwork.
  4. Press two-thirds of this crumble mixture firmly into the bottom of the greased pan to form the crust base.
  5. In a separate bowl, gently toss the mixed berries with granulated sugar, cornstarch, lemon juice, and lemon zest until evenly coated. Be gentle to keep some berries whole.
  6. Spread the berry mixture evenly over the crust layer.
  7. Crumble the remaining third of the crumble mixture loosely over the berries; do not press down.
  8. Bake in the preheated oven for 35-40 minutes until edges are golden brown and fruit juices bubble. Check at 30 minutes if your oven runs hot.
  9. Remove from oven and let cool completely on a wire rack for 1-2 hours to allow filling to set.
  10. Once cool, cut into about 12 bars using a sharp knife wiped between cuts for clean edges.

Notes

Keep the butter cold to ensure a crumbly, flaky topping. Do not overmix the crumble to maintain texture. Use fresh or frozen berries; if frozen, thaw and drain excess juice to avoid soggy bars. Let bars cool completely before cutting to prevent falling apart. Adjust cornstarch to 3 tablespoons if berries are very juicy. Lemon zest adds brightness and is highly recommended. For gluten-free, substitute flour with gluten-free baking blend. For dairy-free, use solid coconut oil or vegan butter. Add nuts for extra crunch if desired.
