Instructions

  1. Step 1: Preheat oven to 375°F (190°C). In a large bowl, toss 4 medium peeled and sliced (1/2-inch thick) apples with 1/4 cup granulated sugar, 1 tsp ground cinnamon, and 1/4 tsp ground nutmeg until evenly coated.
  2. Step 2: Transfer the apple mixture to a greased 8x8-inch baking dish and spread evenly.
  3. Step 3: In a separate bowl, combine 1/2 cup rolled oats, 1/4 cup all-purpose flour, 1/4 cup cold cubed butter, and 1/4 cup chopped walnuts. Use a pastry cutter or fingers to mix until the mixture resembles coarse crumbs.
  4. Step 4: Sprinkle the oat mixture evenly over the apples, pressing down gently to form a compact layer.
  5. Step 5: Bake for 35-40 minutes until the topping is golden brown and the apples are bubbling around the edges.
