Instructions

  1. Step 1: Preheat oven to 350°F. In a large bowl, toss 4 large peeled and sliced Granny Smith apples with 1/3 cup granulated sugar, 1 tsp ground cinnamon, and 2 tsp fresh lemon juice until apples are evenly coated.
  2. Step 2: Spread the apple mixture in an 8-inch square baking dish, pressing down gently.
  3. Step 3: In a separate bowl, combine 3/4 cup rolled oats, 1/2 cup all-purpose flour, 1/2 cup packed brown sugar, and 1/4 tsp salt.
  4. Step 4: Cut 6 tbsp cold diced unsalted butter into the oat mixture using a pastry cutter or fingers until the topping resembles coarse crumbs.
  5. Step 5: Sprinkle the crumble topping evenly over the apples.
  6. Step 6: Bake uncovered for 40-45 minutes until the topping is golden brown and the apple filling is bubbling around the edges.
  7. Step 7: Let cool slightly before serving to allow the filling to thicken.
