Instructions

- Step 4: Using your fingers or a pastry cutter, work the butter into the oat mixture until crumbly and pea-sized clumps form.
- 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.
- Step 6: Let cool for 10 minutes before serving warm with cream or ice cream.
