These Healthy Blueberry Bars have all the deliciousness of a blueberry crumb pie without the time needed to actually make one! It uses nutrient-dense almond flour to make the crust and the crumble on top and is packed with anti-oxidant rich blueberries. These bars are gluten-free, dairy-free friendly, and the ultimate summer dessert!
Gluten-Free Blueberry Bars
There is nothing better than an awesome summer dessert that is easy-to-make and made healthier using simple wholesome ingredients. These gluten-free blueberry bars are just so delicious and so quick to put together! The crust is made out of almond flour and the filling is jam-packed with blueberries that are sweetened just the right amount. We use the same mixture for the crust as well as the crumble topping, and the filling is precooked on the stovetop so it’s just the right texture with minimal baking time!
Type of Blueberries to Use
We tested this with two different types of bluebs: fresh blueberries and frozen wild blueberries. They do result in slightly different flavors and textures but both are equally delicious. The fresh blueberries are typically a bit less sweet, and result in a more set-up final texture. The frozen wild blueberries are sweeter and are a bit more juicy. For this recipe, we prefer to use high-quality frozen wild blueberries. Typically store-bought blueberries aren’t as good of quality as the flash-frozen wild ones available year-round. And if you do find great-tasting fresh blueberries, it’s hard not to want to just eat them straight up! Either fruit you choose to use will work here, though. If you do use wild blueberries, you do not have to defrost them before use since the filling is precooked.
Ingredients Needed:
- Almond flour
- Tapioca flour
- Coconut oil or butter
- Maple syrup
- Vanilla
- Sea salt
- Blueberries (fresh or frozen)
- Tapioca Starch
- Cinnamon
Here are the kitchen tools you need:
- Large bowl
- 8″ x 8″ baking dish
- Parchment paper
- Spatula
- Pot
- Measuring cups
Serving and Storing Blueberry Bars
While these are bars, due to the almond flour they’re a bit trickier to eat handheld. They are best served on a plate with fork. They’re perfect served as is, but go ahead and add a scoop if vanilla ice cream if you want!
These bars are best served within two days after making. You can store overnight in a covered container at room temperature, or in the refrigerator for up to 3 days.

Blueberry Crumb Bars
Ingredients
- For Crust and Crumble:
- 3 cups 288g almond flour
- 2 tablespoons 15 grams tapioca flour
- ⅓ cup coconut oil or butter melted
- 1/3 cup pure maple syrup see note
- 1/2 teaspoon sea salt
For Blueberry Filling:
- 4 cups frozen wild blueberries see note
- 2 tablespoons 15 grams tapioca flour
- ½ teaspoon cinnamon
- 1/4 cup maple syrup
- 1 teaspoon vanilla
Instructions
- Preheat oven to 350ºF and line an 8x8 baking dish with a parchment paper sling.
- In a large bowl add almond flour, tapioca, coconut oil (or butter), maple syrup, and sea salt and mix well until it turns into large crumbles. Place ⅔ of the mixture into the bottom of the prepared pan and press down evenly.
- Bake in the preheated oven for 10-15 minutes, or until the crust looks nearly all baked. Set aside.
- Meanwhile, make the blueberry filling: in a medium saucepan mix together blueberries, tapioca starch, and cinnamon. Then add maple syrup and vanilla and mix well. Cook on medium heat, stirring often, until the filling becomes thick, about 5-8 minutes.
- Pour blueberry mixture into parbaked crust and sprinkle the remaining crumble mixture on top and bake for 20-25 minutes, or until the crumble is lightly browned and the filling is bubbling along the edges.
- Let cool completely before cutting.

Ho w many carbs in this receipe?
Always looking for a recipe to use frozen blueberries. Will try this one.
Would coconut palm sugar be ok instead of maple sugar?
Yes- might change the color slightly.
Would ground oats work in place of the almond flour?
Can coconut flour be substituted for the almond flour ?
No coconut flour is never a 1:1 sub!
do you put the blueberries in frozen or do you thaw before hand.
Can I use potato starch instead of arrowroot?
I made these last week and they turned out absolutely amazing! Going to make these with strawberries next as I pick my own fruit in summer time and have a plethora of frozen fruit still..
These are in my oven right now. The bottom layer smelled amazing when I took it out to add the blueberries!!!
Can I use whole wheat flour in place of almond flour?
I can’t promise the same results as I don’t eat wheat and haven’t tried it, but let us know if you do!
I’m going to try this one soon. Your pages don’t scroll well… Maybe it’s the video ads that you can’t opt out of. I will definitely screen shot it when i use the recipe.
Made these today, but the crumble topping didn’t seem to come together. I used the coconut oil to mix, but, even after baking, the topping remained very flour-y. Ideas?
Maybe not enough coconut oil could be the problem!
Do you happen to have the nutritional value for the Blueberry Crumb Bars?
You can enter them into any online calculator! My Fitness Pal is a good one 🙂
What kind of almond flour? I have the coarser one and the fine blanched kind.
Blanched.
Yum! These look so good. I want to try them out. I’ll have to head out to the store for arrowroot this weekend!
You will love!
Can you use fresh blueberries in this recipe?
Yes!
These bars make me crave summer because I always make blueberry pie with my grandmother! But I’m 100% sure that these taste just as good as blueberry pie but with healthier ingredients!
YES. I hope you love!
These look amazing! I have a nut allergy in our home, can something take the place of almond flour and tapioca flour in this recipe?
You can use ground sunflower seeds!
Arrowroot can be subbed for tapioca here.
Oh my gosh, oat bars are my weakness! Especially blueberry and raspberry flavors. Can’t wait to give this recipe a go!
Could i use coconut sugar in place of the maple?
Yes.
