A sweet and fruity apple and blueberry crumble topped with an easy 5-minute oat crumble. Serve it warm with ice cream, whipped cream, or custard for a comforting, family-friendly dessert.

Top tips
- Let the melted butter cool slightly before mixing with the dry ingredients so it doesn’t make the sugar clump.
- Make the crumble topping ahead and freeze it; it’s handy to have ready when you want a quick dessert.
- Choose old-fashioned rolled oats for a crisper texture; instant oats can go soft.
- Rest the crumble for 10–15 minutes after baking so the filling sets and is easier to serve.
🍴 Serving suggestions
Serve warm with vanilla ice cream, clotted cream, custard, or a spoonful of yogurt or crème fraîche. Leftovers are lovely for breakfast with natural yogurt.
📖 Variations
- Swap or mix berries: raspberries, blackberries or strawberries work well.
- Use frozen blueberries so you can make this dessert year-round.
- Add pears, peaches or plums with the apples for extra depth.
- Stir chopped walnuts, almonds or pecans into the topping for a crunchy nutty note.
- Grate a little nutmeg or add mixed spice to the crumble for warming flavour.
- Split into 6–8 individual ramekins and bake for personal portions.

🥡 Storage
Make ahead: Assemble up to 2 days in advance—layer the fruit, add the topping, cover and refrigerate.
Store: Keep the baked crumble in the fridge for up to 2 days; reheat in the microwave or oven.
Freeze: Freeze for up to 3 months. Bake from frozen—just add a few extra minutes to the cooking time.
❓ FAQs
Tart eating apples like Granny Smith or cooking apples such as Bramley work best, as their acidity balances the sweet topping.
A dry, floury topping usually means there wasn’t enough butter. Add melted butter a tablespoon at a time until the mixture forms clumps.
Terminology varies by region: in the UK it’s often called a crumble; in the US the term crisp is common. Both are baked fruit desserts with a crunchy topping; oats are more typical in a crisp but are frequently used in crumbles too.
