Ingredients

Instructions

  1. Step 1: Preheat oven to 350°F (175°C). In a large bowl, toss 4 peeled and sliced medium apples with 1/3 cup granulated sugar, 1 tsp ground cinnamon, and 1 tbsp lemon juice until evenly coated.
  2. Step 2: Transfer the apple mixture to a greased 8x8-inch baking dish, spreading evenly.
  3. Step 3: In a separate bowl, combine 3/4 cup rolled oats, 1/2 cup all-purpose flour, 1/3 cup brown sugar, 1/4 tsp salt, and 1/2 cup chopped walnuts. Add 6 tbsp cold cubed unsalted butter.
  4. Step 4: Using your fingers or a pastry cutter, work the butter into the oat mixture until crumbly and pea-sized clumps form.
  5. Step 5: Sprinkle the crumble topping evenly over the apples. Bake for 40-45 minutes until the topping is golden brown and apples are bubbling.
  6. Step 6: Let cool for 10 minutes before serving warm with cream or ice cream.
