This is my favorite apple and blueberry crumble recipe - juicy fruit and a golden oat topping. So easy, so comforting, and always gone in minutes.
The apple and blueberry crumble recipe is also wonderfully easy. A bit of chopping, a quick stir, and into the oven it goes. And honestly, Iโve never met anyone who didnโt love a good crumble.

A crumble is one of those desserts that always works. Easy, cheap, and endlessly adaptable with the season - apples and blueberries now, Cherry and Apple Crumble in early summer, plums in fall. This fruit crumble dessert is perfect any time of year.

Recipe Ingredients
Apples: I usually grab whateverโs in the fruit bowl. You donโt need fancy apples; any firm variety works, for instance, Granny Smith, Honeycrisp, or Pink Lady. Check out this Apple Rhubarb Cake, too.
Blueberries: Fresh are lovely, but frozen work just as well - no need to thaw first. They might release a little more juice, but that just makes the crumble extra jammy. If you have more blueberries, make sure you try the Blueberry Panna Cotta.
Oats: Rolled (old-fashioned) oats are the best choice for a topping that crisps up nicely.
Optional add-ins: Cinnamon or nutmeg, a little lemon zest, or a handful of chopped nuts (pecans or walnuts) for extra crunch.

How to make apple and blueberry crumble?
Step #1: Mix flour, sugar, and salt in a bowl. Add the cold, diced butter, and rub it into the flour mixture with your fingers until it looks like coarse crumbs.
Step #2: Toss in your rolled oats and mix lightly. Place the bowl in the freezer while you prepare the rest.
Tip: You can also use the electric mixer with kneading attachments.
Step #3: Peel and chop the apples. Mix them with lemon juice.
Step #4: Combine apples, blueberries, and sugar in the buttered baking dish.
Step #5: Spread the cold crumbles on top.
Step #6: Bake for 25-30 minutes until bubbly and golden.
Tips for the best crumble
Donโt overmix the topping โ the flour, butter, and oat mixture should be crumbly, not doughy. This is key to a perfectly textured apple and blueberry crumble dessert. Try this Cherry Crumble Cake, too.
Bake until topping is crisp and fruit is bubbling - underbaking = soggy topping.
Storage & reheat
Refrigerate: The crumble dessert keeps well in the fridge for 3โ4 days.
Freeze unbaked or baked.
Reheat from the fridge: Place the crumble in a 350โฏยฐF (180ยฐC) oven for 10โ15 minutes to warm through and crisp the topping.
Reheat from frozen (unbaked): Bake straight from the freezer at 350โฏยฐF (180ยฐC), adding 10โ15 minutes to the usual bake time.
Reheat from frozen (baked): Reheat at 350โฏยฐF (180ยฐC) until warmed through and the topping is crisp again.

Serving suggestions

The leftovers are delicious cold or at room temperature; I often have a spoonful straight from the fridge for breakfast.
