Ingredients:

  • 6 medium Cooking Apples (Peeled, cored, and sliced 1/4-inch thick)
  • 1/4 cup Granulated Sugar (for filling)
  • 1/4 cup Light Brown Sugar (for filling)
  • 2 tablespoons All-Purpose Flour (for filling)
  • 1 teaspoon Ground Cinnamon (for filling)
  • 1/4 teaspoon Ground Nutmeg
  • 1 tablespoon Fresh Lemon Juice
  • 1 cup All-Purpose Flour (for topping)
  • 1 cup Rolled Oats (Old-fashioned)
  • 1/2 cup Light Brown Sugar (packed, for topping)
  • 1/4 cup Granulated Sugar (for topping)
  • 1/2 teaspoon Ground Cinnamon (for topping)
  • 1/2 teaspoon Salt
  • 1/2 cup Cold Unsalted Butter (cut into 1/2-inch cubes)

Instructions:

  1. Preheat oven to 375°F (190°C). Lightly grease a 9x9 inch square baking dish or 2-quart casserole dish.
  2. Make the Filling: In a large bowl, combine sliced apples, both sugars, flour, cinnamon, nutmeg, and lemon juice. Toss gently until apples are evenly coated.
  3. Pour the apple mixture evenly into the prepared baking dish and spread into a single layer.
  4. Prepare the Crumble: In a medium bowl, whisk together all dry topping ingredients: flour, oats, sugars, cinnamon, and salt.
  5. Cut in the Butter: Add the cold, cubed butter to the dry ingredients. Use a pastry blender or your fingertips to cut the butter into the mix until the mixture resembles coarse crumbs with some pea-sized chunks remaining.
  6. Assemble: Sprinkle the oatmeal crumble topping evenly and liberally over the apple layer, covering it completely. Do not press down.
  7. Bake for 40–45 minutes, or until the topping is deep golden brown and the apple filling is visibly bubbling thickly around the edges.
  8. Let the crisp rest on a cooling rack for at least 15–20 minutes before serving to allow the juices to set slightly.
