Method

  1. 1

    Preheat oven to 375°F (190°C). Lightly butter a 9x13 inch baking dish.

  2. 2

    In a large bowl, combine the sliced apples and fresh blackberries. Add the 1/2 cup granulated sugar, cornstarch, lemon juice, 1 teaspoon cinnamon, and a pinch of salt. Toss gently until the fruit is evenly coated. Pour the fruit mixture into the prepared baking dish and spread evenly.

  3. 3

    In a separate medium bowl, prepare the oat topping. Combine the rolled oats, all-purpose flour, brown sugar, 1/4 cup granulated sugar, 1/2 teaspoon cinnamon, and 1/4 teaspoon salt. Whisk briefly to combine.

  4. 4

    Add the cold, cubed butter to the dry topping ingredients. Using your fingertips, a pastry blender, or two knives, cut the butter into the mixture until coarse crumbs form, with some pea-sized pieces remaining.

  5. 5

    Evenly sprinkle the oat topping over the fruit mixture in the baking dish.

  6. 6

    Bake for 45-55 minutes, or until the topping is golden brown and crisp, and the fruit filling is bubbly and tender when pierced with a knife. If the topping browns too quickly, you can loosely tent it with foil.

  7. 7

    Remove from oven and let cool on a wire rack for at least 15-20 minutes before serving. This allows the filling to set slightly. Serve warm.

Chef's notes

  • For best results, use a mix of tart and sweet apples, such as Granny Smith with Fuji or Honeycrisp, to achieve a balanced flavor profile.
  • The crumble can be assembled ahead of time, covered, and refrigerated for up to 24 hours before baking. If baking from cold, add an extra 10-15 minutes to the baking time.
  • Leftovers can be stored, covered, in the refrigerator for up to 3 days. Reheat gently in a low oven or microwave until warmed through.
  • Serve warm with a scoop of vanilla ice cream, a dollop of whipped cream, or a drizzle of heavy cream for an extra indulgent experience.
