Ingredients

Scale
  • 4 cups peeled and sliced apples (Granny Smith or Honeycrisp)
  • 2 cups fresh or frozen mulberries
  • 1/2 to 3/4 cup granulated sugar
  • 1 tablespoon lemon juice
  • 2 tablespoons cornstarch
  • 1 teaspoon ground cinnamon
  • 1 cup all-purpose flour
  • 1/2 cup brown sugar
  • 1/2 cup cold unsalted butter, cubed
  • 1/2 cup rolled oats (optional)
  • Pinch of salt

Instructions

  1. Preheat oven to 375°F (190°C) and lightly grease a 9-inch baking dish.
  2. In a large bowl, combine sliced apples, mulberries, granulated sugar, lemon juice, cornstarch, and cinnamon. Toss gently until evenly coated.
  3. Transfer the fruit mixture into the prepared baking dish and spread evenly.
  4. In a separate bowl, mix flour, brown sugar, oats, and salt.
  5. Add cold cubed butter and rub it into the dry ingredients using your fingers or a pastry cutter until the mixture resembles coarse crumbs.
  6. Sprinkle the crumble topping evenly over the fruit filling without pressing it down.
  7. Bake for 40–45 minutes, or until the topping is golden brown and the filling bubbles in the center.
  8. Remove from oven and let rest for 15–20 minutes before serving to allow the filling to set.

Notes

  • Use firm apples like Granny Smith or Honeycrisp for best texture.
  • If using frozen mulberries, do not thaw before mixing with apples.
  • Add an extra 1/2 tablespoon cornstarch if the fruit is very juicy.
  • Let the crumble cool slightly before serving for cleaner slices.
  • Store leftovers in the refrigerator for up to 4 days.
