Ingredients

Scale
  • 1 ¾ cups (220g) all-purpose flour
  • 1 cup (90g) rolled oats
  • ⅔ cup (135g) granulated sugar
  • ⅓ cup (70g) packed brown sugar
  • ¾ cup (170g) unsalted butter, cold and cubed
  • 1 teaspoon vanilla extract
  • ¼ teaspoon salt
  • 3 cups (about 450g) black raspberries, fresh or frozen
  • ⅓ cup (65g) granulated sugar
  • 2 tablespoons cornstarch
  • 1 tablespoon lemon juice
  • 1 teaspoon lemon zest (optional)

Instructions

  1. Preheat your oven to 350°F (175°C). Lightly grease a 9×13 inch pan or line it with parchment paper, leaving an overhang for easy removal.
  2. In a large mixing bowl, combine 1 ¼ cups (155g) of the flour, oats, granulated sugar, brown sugar, and salt. Add the cold, cubed butter. Using a pastry cutter or your fingertips, cut the butter into the mixture until it resembles coarse crumbs with some pea-sized pieces. Chill in the fridge for 10 minutes if kitchen is warm.
  3. Press half of the crumble mixture firmly into the bottom of the prepared pan. Bake this crust for 12-15 minutes or until just starting to turn golden.
  4. While the crust bakes, mix black raspberries, sugar, cornstarch, lemon juice, and lemon zest in a medium bowl. Stir gently to combine without crushing the berries.
  5. Remove the crust from the oven and spread the berry filling evenly over it.
  6. Sprinkle the remaining crumble mixture evenly over the filling without pressing down.
  7. Bake for 35-40 minutes until the top is golden brown and the filling is bubbling around the edges. Cover loosely with foil if the top browns too quickly.
  8. Cool completely in the pan on a wire rack. Use the parchment overhang to lift the bars out and cut into squares or rectangles.

Notes

Keep butter cold to ensure a crumbly streusel. Pre-bake the crust to prevent sogginess. Let bars cool completely or refrigerate before cutting for clean slices. Cover with foil if streusel browns too fast. Use parchment paper for easy removal.
