What is apple & blueberry crumble?
If you grew up eating crumbles or crips, you’re already familiar with the experience. You first slice through a buttery, crumbly topping, then draw your spoon through a mixture of tender apples with brilliant purple pops of blueberry.
This apple blueberry crumble recipe is a twist on the classic apple crumble. Blueberries add color and fresh flavor to balance the fresh apple pieces, and I use a crumble topping made with oats for extra crunchiness.
It’s a lovely summer dessert the whole family will love.

Apple Blueberry Crumble Ingredients
Fruit Filling
- Fresh blueberries: Start with fresh, juicy blueberries. This is a great way to use up excess berries from your garden or after visiting a u-pick! (You can also use frozen blueberries in a pinch.)
- Tart apples:I prefer to use Granny Smith apples, but you can really use any type of apple. Macintosh apples or Pink Lady apples would be a great alternative.
- All purpose flour: This helps create a thick blueberry apple filling. If you don’t thicken the fruit mixture, it will be fruit soup (which is still delicious).
- Sugar: Although the fruit has its natural sweetness, it can help to add a bit of sugar or maple syrup to highlight those fresh flavors.
- Salt: Salt enhances flavor and makes this sweet dessert taste sweeter!
Crumble Topping
- Oats: Technically, this is a crisp topping because it contains oats. I prefer oats in my crumbles and crisps and think you will, too!
- Flour: The flour will help hold the sugar, oats, and butter together to get the perfect golden streusel on top!
- Brown sugar: Brown sugar has a rich, delicious flavor and it’s perfect for forming a nice crumble.
- White sugar: White sugar adds sweetness without flavor and balances this topping beautifully.
- Unsalted butter: This is the key to the best crisp! Start with very cold butter and cut it into tiny cubes for best results.
- Salt: You just need a pinch or two to get the right level of salt in this blueberry apple crumble recipe.
- Vanilla extract: This is optional, but vanilla highlights the sweetness in this fruity crumble really nicely.
How to Make Apple and Blueberry Crumble
- Preheat the oven to 350 degrees F.
- Add your fruit mixture ingredients (fruit, sugar, flour, sand a pinch of salt) directly to the baking dish and stir them to combine. Adjust them until they make an even layer.
- In a small bowl, combine crumble topping ingredients. Using a pastry blender, mix the butter pieces into the crumble topping until the mixture looks like crumbly sand.
- Add the crumble mixture on top of the fruit mixture and bake for 45-50 minutes or until the topping is golden brown and the fruit is bubbling in the corners of the pan.
- Remove from the oven and let the apple blueberry crumble rest for 25-30 minutes before serving with a scoop of ice cream or a dollop of whipped cream.
Storing
Store leftover crumble in an airtight container in the fridge for 4-5 days. To reheat, microwave a serving for approximately 1-2 minutes or bake it at 350 degrees for 4-5 minutes or until fully heated.
Serving Suggestions
Crisps & crumbles taste absolutely heavenly with a scoop of vanilla ice cream or a nice big dollop of whipped cream. You can even cover them in a creamy custard for a really wonderful, cozy apple blueberry experience.
Tips & Variations
- Work with cold butter. If your butter isn’t really cold, it will melt into the blueberry apple mixture instead of turning into a delicious crumble topping.
- Get chilly. I actually like to chill my crumble topping before adding it to the pan. This isn’t necessary, but it gives me the most perfect, sky-high crumble!
- Add spices & seasonings. You can easily tweak this fruit crumble recipe by adding your favorite spices (cinnamon, allspice, Chinese 5 Spice) or adding aromatic ingredients like lemon juice, lemon zest, lavender extract, cardamom extract, etc.
- Add nuts. For extra crunch and flavor, replace 1/4 cup of the oats with chopped almonds or pecans.
FAQs
Traditionally, crumbles do not contain oats. They often have a golden, bubbly crumble made by mixing melted butter with flour and sugar. However, it’s really common to find crumbles made with oats these days.
Since I prefer the crunchy texture of the oats, I almost always make crumble recipes with crisp toppings instead of a traditional crumble topping. I think you will, too!
Yep! Honestly, crisps and crumbles are so flexible. The secret is to make sure you add the right amount of flour in the fruit filling and use a consistent crumble recipe. You can either add or replace some of the blueberries with blackberries, cherries, raspberries, strawberries, and more.
Yep! You can certainly use frozen blueberries instead of fresh fruit. No need to let the blueberries thaw; they’ll cook fine from frozen. You may need to add a few extra minutes to the baking time to allow the berries to gel with the apples.
