🧈 Butter Tip: I put the butter stick on the counter for 10 minutes while I assembled the ingredients.
Is this a blueberry crumble or a blueberry crisp?
A crumble is mostly floury in texture. A crisp recipe, on the other hand, is made with crisp toppings. The topping has a more grainy texture. Oats are generally added to a crisp to make it more, well, “Crispy”.
You can easily turn this crumble into a crisp by adding ground rolled oats to it. A crisp version of this vegan dessert sounds so delicious right now!
I used a sugar and flour base for the crumble. If you want something different, try this strawberry crunch topping, which uses Oreos.
🫐 Crumble Tip: For more texture to the blueberry crumble, lightly grind about 5 pecans and mix them with the crumble.
The use of ground flax seeds
Ground flax seeds help add a little more texture to the recipe. They also make the crumble taste a little less floury. You can also add a little bit of salt, lemon zest, and cinnamon to bring out the flavors of the seeds.
Ground flax seeds are easily found in all grocery stores and even in big-box stores. If you can’t find them locally, there is always Amazon!

Splatter Tip: When you place the pie in the oven, put a baking dish below to catch any splatter while the pie is bubbling.
Can’t decide between frozen and fresh blueberries?
I experimented, so that you don’t have to! I made it with both fresh blueberries and frozen ones.
Both recipes tasted great. The only thing to keep in mind with the frozen one is that it will get watery. So, don’t thaw the frozen blueberries first.
Put them in the pan and place it in a preheated oven for about 3 minutes while you assemble the crumble mixture.
Carefully remove it from the oven, top it with the crumble, and cook again for 25 minutes
Use the blueberries you have on hand, whether they are fresh or frozen.
🧑🍳 Baking Tip: This recipe is baked in the oven, but you can air fry it. Use the same temperature, but reduce the time by about 5 minutes.
What other fruits can I make into a crumble?
- Strawberries
- Blackberries
- Raspberries
- Mixed berries
- Apples
- Peaches
Not a fan of blueberries? I hear you, I know that not everyone will enjoy blueberries. You can go for this Bisquick apple cobbler instead because I know you love your apples!

The magic of lemon in this dessert
Some blueberries are tangy and some are sweet!
So, how do you bring together these 2 extremes of taste?
That’s the magic of lemon juice!
It evens out the sweetness of the berries and gives this crumble unforgettable flavors.
So, use lemons or lime juice to make the berries taste even. Adding lemon zest will enhance the flavors of this dish.
Making this blueberry crumble vegan
The 2 ingredients in this recipe that to be on alert for, if you want to bake a vegan version: Butter and Sugar
Traditional butter is not vegan because it is not dairy-free. We are fortunate to be in an era where brands like Earth Balance, Miyoko, and Target’s Good & Gather make vegan butter.
As for sugar, many people are surprised to hear that some can be non-vegan.
Most of the sugars are cut or charred with animal bones. The industry is changing significantly and finding better ways to cut sugar. However, many are still using the old ways.
Brands like Wholesome Organic Sugar use fair trade practices and make vegan-friendly sugars. They are available in stores and online.
For this recipe, I recommend using (Affiliate Link) Wholesome Organic Light Brown Sugar as it tastes so natural. If you like the taste of coconut sugar, you can use it in this recipe.

Answering your questions
Yes, you can use frozen blueberries in a blueberry crumble. DO NOT thaw them before using. Make the crumble first, then add the frozen berries to a pan. Top with the crumble and cook as instructed.
A cobbler has a biscuit top. Can be a dough biscuit top or a puff pastry top. A crumble, on the other hand, has a softer top that almost dissolves with the berry bottom.
Yes, you can use mixed berries to make this berry crumble recipe. Use raspberries, blackberries, strawberries, and even wild blueberries.
The crumble will stay for about 1 week in the refrigerator.
You can freeze it for about 1-2 months. When eating it frozen, don’t thaw it. Put it directly into a 300° preheated oven and bake until defrosted (about 15 minutes)
How to serve blueberry crumble?
- Serve with a scoop of vanilla ice cream.
- Serve it with apple crisp.

Version 1
From time to time, I will go through old recipes to update the content. Sometimes, I update just the images, and sometimes, I give the recipe a complete makeover.
This recipe was perfect as it was, so I didn’t feel the need to update it. But I did edit the post itself to shorten it. Additionally, I separated out the segments and shortened paragraphs to make it easier to read.
