Apple and Blueberry Crumble Recipe with Crisp Oat Topping

Indulge in an apple and blueberry crumble packed with tender apples, juicy blueberries, and a buttery golden streusel topping.

Fruit desserts are always a crowd-pleaser — from apple pie cupcakes to cherry pie, pear cobbler, strawberry ice cream or an apple crumble tart. Combining apples and blueberries brings together bright summer and cozy autumn flavors: sweet, tart, floral and lightly acidic notes in every bite.

Why This Recipe Works

• Simple — Toss the fruit with the filling ingredients, prepare a quick streusel, bake, and serve warm or chilled. It pairs beautifully with vanilla ice cream or peaches-and-cream ice cream.
• Textures — Tender baked apples and bursting blueberries contrast with a buttery, golden streusel for an irresistible bite.
• Seasonal versatility — Enjoy this crumble year-round: pick blueberries in summer and apples in fall, or use frozen berries when fresh ones aren’t available.

Ingredient Notes

• Flour — All-purpose flour works well in the crumble topping for structure and binding.
• Oats — Rolled oats add chew and a nutty flavor to the streusel.
• Sugar — Light brown sugar gives the crumble a subtle molasses note; it’s used in both topping and filling.
• Butter — Adds richness and helps the topping become crisp and golden. A bit of butter in the filling enhances flavor.
• Cornstarch — Thickens the filling as it bakes so the fruit becomes saucy without being runny.
• Cinnamon — A warm, aromatic accent that complements apple and blueberry — use sparingly to let the fruit shine.
• Salt — A pinch boosts and balances sweetness.
• Apples — Choose firm, slightly tart apples (Granny Smith is ideal). Peel, core and slice evenly so they cook uniformly.
• Blueberries — Use plump fresh berries when possible; frozen work fine too.
• Lemon juice — A splash brightens the filling and prevents apple browning.
• Vanilla extract — A small amount deepens overall flavor.

Ingredient Swaps

Swap ingredients to suit dietary needs or pantry supplies:

• Use whole wheat flour for a nuttier crumble topping.
• Dark brown sugar adds more molasses flavor; granulated sugar yields a more neutral sweetness.
• For dairy-free baking, substitute melted coconut oil or a neutral vegetable oil for the butter.
• Apples like Braeburn, Golden Delicious or Honeycrisp are good alternatives to Granny Smith.

Make the crumb topping by mixing flour, oats and brown sugar in a bowl. Pour in melted butter and stir until the mixture resembles coarse crumbs.

Prepare the filling by combining light brown sugar, cornstarch, cinnamon and salt in a large bowl. Add sliced apples, blueberries, melted butter, lemon juice and vanilla, then toss gently until the fruit is evenly coated.

Spread the filling into a 9-inch pie dish and evenly scatter the crumb topping over it. Bake at 375°F for 35–40 minutes, until the topping is golden and the filling bubbles. Let the crumble rest about 10 minutes before serving.

Pro Tips / Notes

• Fresh blueberries are best, but frozen berries work well when out of season.
• Slice apples uniformly so they cook evenly.
