Method
Preheat and prep the dish
- Preheat the oven to 350F. Generously butter a 9x13 baking dish so the topping can crisp and release cleanly.
Make the apple filling
- Toss the apple slices with granulated sugar, all-purpose flour, and cinnamon. Pour into the baking dish and spread into an even layer.
Assemble the crumble topping
- Combine all-purpose flour, rolled oats, brown sugar, granulated sugar, cinnamon, baking powder, and salt in a bowl. Mix until the dry ingredients are evenly distributed.
- Cut in the cold cubed butter with your hands until large, butter-streaked clumps form. Stop once the mixture looks crumbly but still clumps together when pinched.
Bake
- Pour the topping over the apples and spread evenly to cover the surface. Ensure the crumble reaches the edges so it turns golden and crisp.
- Bake for 55-60 minutes until the topping is golden brown and the apple filling bubbles at the edges. Rest briefly during serving so juices thicken slightly.
Serve
- Serve warm with whipped cream or ice cream. Add right before eating for the best contrast between crisp topping and warm fruit.
Notes
Pro tip: use cold butter and handle the crumble as little as possible so it forms big clumps that bake up crisp. Storage: cover and refrigerate up to 4 days; reheat in a 350F oven until warmed through. Freezer: bake fully, cool, then freeze up to 2 months and reheat from thawed (or bake from frozen at 350F longer). Dietary swap: for a lower-sugar option, replace about half the granulated and brown sugar with an equal-measure sugar substitute made for baking, and expect a slightly softer crumble.
