The filling for this apple blueberry crumble is easy.
Chopped Pink Lady apples, blueberries sugar, cinnamon, lemon, vanilla and salt.
You don’t even have to cook the filling before baking!
The crumble topping is one of my best.
It takes flour, old-fashioned rolled oats, brown sugar, cinnamon and melted butter.
No need to rub the butter into the flour either.
When I have tested crumble toppings, I find the results of melted butter triumph rubbing in cold butter.
Why? Because melted butter creates a better crunch, flavor and it’s quicker!
The amount of butter may seem heavy in this recipe but trust the process.
It creates the most gorgeous and crisp texture after the crumble has baked.

What is the Difference Between Crumble and Crisp?
Crumbles and Crisps both offer a fruity filling under a crumbly topping.
A traditional crumble topping generally consists of flour, sugar, and butter, while a crisp features oats in its topping for added crunch and texture.
Nowadays, the two terms, crumble and crisp are often used interchangeably.
What Type of Apples are Best to Use?
The ideal apples for a crumble are those that maintain their structural integrity during the baking process and offer a balance of sweetness and tartness.
Popular options include Granny Smith, Pink Lady, Honeycrisp, Fuji and Golden Delicious.
For this blueberry apple crumble, I used Pink Lady Apples.
Can I use Frozen Blueberries?
Yes! Frozen blueberries work great in this apple crumble. You do not need to thaw them beforehand.
Can I Make Blueberry Apple Crumble Ahead of Time?
Yes, you can make Blueberry Apple Crumble ahead of time and bake it later.
Cover tightly and refrigerate this crumble for up to 24 hours before baking per the recipe instructions.
Ingredient Notes & Substitutions
- Apples: Use any variety you like, I used Pink Lady Apples. My second choice would be Granny Smith or Honeycrisp Apples.
- Blueberries: You can use either frozen or fresh blueberries. If using frozen, add them directly from the freezer into the filling mixture—no thawing needed.
- Granulated sugar: I used golden/raw granulated sugar for its added flavor. You can substitute it with regular white granulated sugar.
- Lemon juice: For best flavor results, use freshly squeezed lemon juice.
- Cinnamon: Ground cinnamon works best.
- Vanilla extract: Can be substituted with a 1/2 teaspoon of vanilla paste.
- Salt: Any fine salt will do.
- All-purpose flour: Also known as plain flour in Australia. Make sure to accurately measure your flour for the best results.
- Old-fashioned rolled oats: Whole oats produce the best crisp results rather than using steel cut oats or quick oats.
- Unsalted butter: Use butter that comes in a block. Can be substituted with salted butter or vegan block butter.
Step By Step Instructions (with photos)

Step one: Preheat the oven to 180ºC (350ºF) fan-forced. Grease a 25cm (10-inch) round pie dish with butter and set aside.

Step three: To the apples, add blueberries, sugar, lemon juice, cinnamon, vanilla and salt.
Mix with a wooden spoon until well combined.
Step four: Sprinkle over flour and mix through.
Step five: Spoon filling into the greased pie dish and set aside.
Step six: In a large mixing bowl, add flour, oats, sugar, and cinnamon. Mix until well combined.
Step seven: Pour over melted butter and mix with a wooden spoon or spatula until well combined. You can also use your hands for this step.
Step eight: Sprinkle the crumble over the apple blueberry filling.
Step nine: Bake for 40-45 minutes until the crumble is golden all over and the filling is bubbling.

Expert Tips
- Measure your baking ingredients accurately: Check out my helpful guide on how to measure basic ingredients.
- Grease your pie dish: Scoop out your baked fruit crumble without it sticking to the dish by greasing it liberally with butter beforehand.
- Browning apples: Don’t leave your chopped apples sitting out too long as they’ll turn brown. Once the filling is assembled, the added lemon juice stops the apples from browning.
Serving Suggestions
- Vanilla Ice Cream: Adds creaminess and complements the crumble’s warmth.
- Whipped Cream: Provides a light, airy contrast to the crumble’s texture.
- Custard Sauce: A traditional choice that adds a rich, velvety layer on top.
- Greek Yogurt: Offers a healthier, tangy alternative to ice cream or custard.
- Coffee or Tea: As a relaxing dessert after dinner, enjoy it with a hot cup of tea, coffee, rum hot chocolate or hot milo.
- Caramel Drizzle: Drizzle the baked crumble with caramel sauce for a decadent dessert.
