Apple Blueberry Crumble

I make this apple blueberry crumble when I want something sweet. You get soft apples and juicy berries under a crispy top. It’s like pie but easier.
No crust to worry about. My kids love this dessert every time I bake it. The smell fills our whole house.
You can make this with things you already have. It works great for new cooks, too. This recipe is simple and quick.
Why You’ll Love Apple Blueberry Crumble?
- This dessert takes just thirty minutes to put together before baking.
- You can use frozen fruit or fresh fruit from the store.
- The top stays crispy while the fruit gets soft and sweet.
- It tastes great with ice cream or cream on top, always.
- Your house will smell like a bakery while it bakes hot.
Ingredients You’ll Need
- Apples: I pick tart apples like Granny Smith. They stay firm when you bake them hot.
- Blueberries: Fresh ones work best. You can use frozen ones if you thaw them out first.
- Sugar: White sugar makes the fruit sweet. It helps make the top turn golden brown, too.
- Flour: This makes the fruit juice thick. It also helps build the crumble top that gets crispy.
- Butter: Cold butter makes the top crisp. It gives a rich taste that makes this dessert so good.
- Oats: These make the top bumpy and fun. They taste like granola when they get baked golden.
- Cinnamon: This spice makes it smell amazing. It adds a warm taste that goes great with fruit flavors.
- Salt: Just a tiny bit makes all flavors pop. It balances out all the sweet parts perfectly.
- Vanilla: This makes the fruit taste richer. It adds depth that plain fruit just can’t give you.
- Lemon juice: Fresh juice stops apples from turning brown. It adds a bright taste to balance sweet flavors.

Equipment You’ll Need
- Baking dish: A big dish works best for this recipe. It feeds about eight people when done.
- Mixing bowls: You need two bowls to mix fruit and topping in separate batches for best results.
- Measuring cups: Right amounts matter for good results. These help you get it right every single time.
- Knife: A sharp knife cuts apples fast and safely. Dull knives are hard to use and dangerous.
- Cutting board: Use a big board so you have room. Small boards make cutting fruit really hard.
How to Make Apple Blueberry Crumble?
This easy recipe mixes sweet fruit with crispy topping for the best homemade dessert you can make.
Step 1: Heat your oven to 375°F and grease your dish with butter so nothing sticks later.
Step 2: Peel and cut apples thinly slices and mix with berries, sugar, flour, cinnamon, vanilla, and lemon juice.
Step 3: Mix flour, oats, sugar, and salt in another bowl, then add cold butter until it looks like crumbs.
Step 4: Put the fruit mix in your dish and spread it flat across the bottom so it bakes evenly.
Step 5: Add crumble top over fruit and bake 35-40 minutes until golden brown and fruit bubbles up.
Step 6: Let it cool for 10 minutes so the juice gets thick and doesn’t run out everywhere.

Tips for the Best Apple Blueberry Crumble
- Use cold butter when making the top for the best crispy results every time.
- Don’t mix too much or the topping gets heavy instead of light and crispy.
- Taste your fruit first and add more sugar if your apples are really tart.
- Cover with foil if the top gets too brown during the last ten minutes.
- Let it sit after baking so the juice thickens up and stays put nicely.
Variations and Substitutions
- Try pears instead of apples for a different taste that still works great with berries.
- Add nuts like pecans to your topping for extra crunch and rich nutty flavor.
- Use other berries like raspberries if you can’t find blueberries at the store today.
- Make it wheat-free by using almond flour instead of regular flour in both parts.
- Use less sugar if your fruit is sweet or you like things less sugary.
Make-Ahead and Storage Tips
- Put it together the night before and keep it cold, then bake when you want.
- Keep leftovers covered in the fridge for 4 days and heat up single servings.
- Freeze before baking for three months, no need to thaw it out first either.
- Heat single portions in the microwave for thirty seconds or oven until warm all through.
- Keep toppings separate if making ahead, so it doesn’t get soggy from fruit juice.

Serving Ideas
- With vanilla ice cream, I serve warm crumble with cold ice cream for the best mix of hot and cold.
- Add whipped cream: Fresh cream makes this feel fancy and adds a light texture to every single bite you take.
- Pour caramel sauce: Warm caramel makes this simple dessert taste like it came from a fancy restaurant kitchen.
- Serve with coffee: This crumble goes great with morning coffee and makes a perfect weekend breakfast treat for everyone.
