A quick and easy jumbleberry crumble perfect for summer gatherings, featuring a mix of fresh or frozen berries with a crunchy, buttery oat topping.

Ingredients

Scale
  • 4 cups (600g) mixed berries (blueberries, raspberries, blackberries, strawberries), hulled and halved if large
  • 1/3 cup (65g) granulated sugar
  • 1 tablespoon fresh lemon juice
  • 2 tablespoons cornstarch
  • 1 teaspoon vanilla extract
  • 1 cup (130g) all-purpose flour
  • 1/2 cup (45g) old-fashioned rolled oats
  • 1/3 cup (70g) packed light brown sugar
  • 1/2 cup (115g) unsalted butter, cold and cubed
  • 1 teaspoon ground cinnamon
  • 1 teaspoon lemon zest
  • Pinch of salt

Instructions

  1. Preheat your oven to 375°F (190°C). Lightly grease a 9-inch baking dish with butter or non-stick spray.
  2. In a large mixing bowl, combine mixed berries, granulated sugar, fresh lemon juice, cornstarch, and vanilla extract. Gently toss until berries are evenly coated.
  3. Transfer the berry mixture into the prepared baking dish, spreading evenly.
  4. In another bowl, whisk together all-purpose flour, rolled oats, light brown sugar, ground cinnamon, lemon zest, and salt.
  5. Add cold, cubed butter to the dry ingredients. Use a pastry cutter, two forks, or fingertips to cut butter into the mixture until it resembles coarse crumbs with some pea-sized bits.
  6. Sprinkle the crumble topping evenly over the berry filling without packing it down.
  7. Bake for 35-40 minutes or until the topping is golden brown and the filling is bubbling around the edges.
  8. Cool for at least 10 minutes before serving to let the juices thicken further.

Notes

Keep the butter cold before mixing to ensure a crumbly topping. If topping browns too fast, tent with foil. Drain excess liquid from frozen berries to avoid watery filling. Lemon zest in topping adds brightness. Can substitute almond flour and dairy-free butter for gluten-free and vegan options.
