Ingredients

Scale
  • 4 cups (600g) mixed berries (blueberries, raspberries, sliced strawberries, blackberries), fresh or frozen
  • ⅓ cup (65g) granulated sugar
  • 1 tablespoon (15ml) lemon juice
  • 2 tablespoons (16g) cornstarch
  • 1 cup (90g) old-fashioned rolled oats
  • ¾ cup (95g) all-purpose flour
  • ⅓ cup (70g) brown sugar
  • ½ cup (115g) unsalted butter, cold and cubed
  • 1 teaspoon ground cinnamon
  • ¼ teaspoon salt

Instructions

  1. Preheat your oven to 350°F (175°C).
  2. In a large bowl, combine mixed berries, granulated sugar, lemon juice, and cornstarch. Gently toss until berries are evenly coated.
  3. Transfer the berry mixture to an 8×8-inch baking dish and spread evenly.
  4. In a separate bowl, mix rolled oats, all-purpose flour, brown sugar, ground cinnamon, and salt.
  5. Cut in the cold, cubed butter using a pastry cutter or fingers until the mixture is crumbly with pea-sized butter pieces.
  6. Sprinkle the oat topping evenly over the berry filling without pressing down.
  7. Bake for 40-45 minutes until the topping is golden brown and the berry filling is bubbly around the edges. If topping browns too quickly, cover loosely with foil halfway through baking.
  8. Cool slightly before serving. Serve warm with optional vanilla ice cream or whipped cream.

Notes

Use cold butter for a flaky oat topping. If berries are very juicy, add an extra ½ tablespoon cornstarch to prevent runny filling. Cover with foil if topping browns too fast. Frozen berries can be used year-round; thaw and drain excess juice before mixing. For gluten-free, substitute flour with almond or gluten-free flour blend and ensure oats are certified gluten-free. For vegan, replace butter with coconut oil or vegan butter and brown sugar with maple syrup.
