Ingredients

Scale
  • 2 ½ cups (315 g) all-purpose flour
  • 1 cup (200 g) granulated sugar
  • 1 cup (227 g) cold unsalted butter, cut into small cubes
  • ½ teaspoon salt
  • 4 cups (600 g) fresh blackberries
  • ½ cup (100 g) granulated sugar
  • 2 tablespoons fresh lemon juice
  • 2 tablespoons cornstarch
  • 1 teaspoon vanilla extract (optional)

Instructions

  1. Preheat your oven to 350°F (175°C). Grease a 9×13 inch baking pan lightly with butter or line it with parchment paper, leaving some overhang for easy removal later.
  2. In a large mixing bowl, combine 2 ½ cups flour, 1 cup sugar, and ½ teaspoon salt. Add the cold, cubed butter. Using a pastry cutter or two forks, cut the butter into the dry ingredients until the mixture resembles coarse crumbs with some pea-sized bits.
  3. Press half of the crumb mixture evenly into the bottom of the prepared pan, creating a compact, level crust layer.
  4. In a separate bowl, combine the blackberries, ½ cup sugar, 2 tablespoons lemon juice, 2 tablespoons cornstarch, and 1 teaspoon vanilla extract if using. Gently toss to coat the berries evenly without crushing them.
  5. Carefully spoon the blackberry filling over the pressed crust layer, spreading it out evenly but gently.
  6. Sprinkle the remaining crumb topping evenly over the blackberry layer without pressing down.
  7. Bake the bars for 45-50 minutes, or until the crumb topping is golden brown and the blackberry filling is bubbling around the edges.
  8. Remove the bars from the oven and set on a cooling rack. Let them cool completely before slicing to help the filling thicken and bars hold their shape.
  9. Use a sharp knife to cut into bars, wiping the knife between cuts for clean edges. Serve with whipped cream or vanilla ice cream if desired.

Notes

Keep butter cold and work quickly to maintain crumbly texture. Let bars cool completely before slicing for clean cuts. Tent with foil if topping browns too quickly. Use frozen blackberries thawed and drained to avoid sogginess. Substitute coconut oil for dairy-free and gluten-free flour blends for gluten-free versions.
