Ingredients
  

Berry Filling
  • 4 cups mixed berries (fresh or frozen, such as strawberries, blueberries, raspberries, and blackberries)
  • 2 tablespoons granulated sugar adjust to sweetness of berries
  • 1 tablespoon cornstarch (or all-purpose flour)
  • 1 tablespoon fresh lemon juice
  • 1 teaspoon vanilla extract
  • Pinch salt
Oat Crumble Topping
  • 1 cup rolled oats (old-fashioned oats recommended)
  • 1/2 cup all-purpose flour
  • 1/3 cup packed brown sugar
  • 1/4 cup granulated sugar
  • 1/2 teaspoon ground cinnamon
  • 1/4 teaspoon ground nutmeg
  • 1/2 cup (1 stick) cold unsalted butter, cut into small cubes

Equipment

  • 2-quart baking dish
  • Large Bowl
  • Medium Bowl
  • - Baking Sheet

Method
 

  1. Preheat your oven to 375°F (190°C). Lightly grease a 2-quart baking dish (an 8x8 inch or a similar round or oval dish works well).
  2. In a large bowl, combine your mixed berries. If using frozen berries, there's no need to thaw them completely; a little frost is fine. Add the granulated sugar, cornstarch (or flour), fresh lemon juice, vanilla extract, and a pinch of salt to the berries. Gently toss everything together until the berries are evenly coated.

  3. Pour the berry mixture evenly into the prepared baking dish. Spread them out so there are no large clumps.
  4. In a separate medium bowl, whisk together the rolled oats, all-purpose flour, packed brown sugar, granulated sugar, ground cinnamon, and ground nutmeg. These dry ingredients form the base of your delicious crumble.

  5. Add the cold, cubed unsalted butter to the dry ingredients. Using your fingertips, a pastry blender, or two forks, cut the butter into the dry ingredients until the mixture resembles coarse crumbs with some pea-sized pieces of butter still visible. Don't overmix; you want those little butter pockets to create pockets of crispiness.

  6. Evenly sprinkle the oat crumble mixture over the top of the berry filling in the baking dish. Ensure the entire surface of the berries is covered with the crumble.
  7. Place the baking dish on a baking sheet (this catches any potential berry drips) and bake in the preheated oven for 35-40 minutes, or until the topping is golden brown and crisp, and the berry filling is bubbly around the edges.
  8. Once baked, carefully remove the Triple Berry Crisp Oat Crumble from the oven. Let it stand for at least 10-15 minutes before serving. This allows the filling to set slightly, making it easier to serve and preventing it from being scalding hot.

Notes

Best served warm with a scoop of vanilla ice cream or a dollop of whipped cream.
