Why do I call these tender, crumbly keto blueberry treats “breakfast bars”? They could easily be a luscious sweet snack or a decadent dessert. But there’s something about blueberries that always makes me want to eat them for breakfast.
I enjoy them in keto blueberry muffins and tender keto scones. And I adore topping keto waffles with fresh blueberries from the farmer’s market.
Reader’s Thoughts
“Delicious! Made with blueberries picked from my own blueberry bushes. Thanks for another delicious recipe!” — Pam
And given the state of my life right now, if I want to eat a blueberry crumb bar for breakfast, I am going to do it. I don’t recommend getting in my way, you might get hurt! And they are a delightful way to enjoy a bakery-style treat without all the carbs.
With a buttery almond flour crust, a juicy blueberry filling, and a sweet crumb topping, they strike the perfect balance between indulgent and wholesome. They’re easy to make and perfect for breakfast, snacking, or even dessert.

Ingredient Notes
- Blueberries: You can use fresh or frozen blueberries. Both work equally well.
- Sweetener: I recommend an erythritol-based sweetener for the crust, to allow it to firm up properly. For the filling, you can use allulose for a nice, syrupy sweet fruit mixture. If you can’t use allulose, try powdered sweetener.
- Glucomannan: Most cobbler bars take cornstarch to help thicken the filling, but a little glucomannan or xanthan gum does an admirable job for this keto version.
- Almond flour: You really do need to use a good finely ground almond flour for this recipe. No other nut meal or flour will give you the same shortbread like consistency.
- Coconut flour: A little coconut flour in the crust mixture helps offset the moisture in the almond flour.
- Shredded coconut: Be sure to use unsweetened shredded coconut.
- Kitchen staples: Butter, vanilla extract, and salt
Recipe Overview: How to make Keto Blueberry Bars
- Prepare the blueberry filling: Simmer the berries with water and sweetener until they release their juices. Then whisk in the glucomannan for a nice, thick filling.
- Prepare the crust mixture: Whisk the dry ingredients together and stir in the melted butter until the mixture begins to clump together.
- Par-bake the bottom crust: For a bottom crust that doesn’t get soggy, you want to bake it for 10 minutes first, then let it cool. This allows it to firm up.
- Add the filling: Spread the filling over the bottom crust after it cools. Take the remaining crumb mixture and sprinkle it generously overtop.
- Bake again: Bake another 20 to 25 minutes, or until the crust is light golden brown.
Tips for Success
You can use an 8×8 or a 9×9 inch pan. For the bigger pan, the bars will be thinner and will bake through more quickly so be sure to keep your eye on them.
I recommend metal baking pans as they cook more evenly. Ceramic and glass pans heat up more slowly but they also hold the heat longer, which can affect the outcome of your recipe. If you only have glass or ceramic, try lowering the temperature of your oven by 25 degrees. Be sure to watch them carefully and look for the visual cues for doneness.
If you’re not a fan of coconut, you can replace the shredded coconut with the same amount of almond flour. You can also replace the coconut flour with another 1/3 cup of almond flour.
Sweetener Options
If you want your crust to be crisp, you really need to use an erythritol based sweetener that contains no allulose whatsoever. The filling works best with allulose, as it makes it more syrupy and thick. But you can use any sweetener here, since you will be using some thickener as well.
Frequently Asked Questions
You can store these bars in a covered container in the fridge for up to a week. Do note that the crust does become softer the longer they sit.

I made these with huckleberries since that’s what I had on hand and they are amazing!
Looking forward to making these blueberry bars
These are delicious and easy to make. Thanks Carolyn.
Hi Carolyn, I made a batch of these this evening. They are a hit with my very picky husband, I am trying to get him to eat less sugar. I split the flour between sunflower and almond flour which he prefers. Thank you for your recipes.
Where is the recipe????
Click the link at the bottom of the post. 🙂
Delicious! Made with blueberries picked from my own blueberry bushes. Thanks for another delicious recipe!
So, is this recipe in any of your books? I think I just need to but those and same on ink and paper ,lol!!
Well, I certainly can’t type or proof today, lol
No sorry. Most of my recipes are not in my books. Publishers want new material, not material that’s already available for free.
Can you give tips on doubling the recipe? What should the cook time be? I have a ton of fresh berries I harvested and want to make a double batch.
I’m sorry, you will have just watch it carefully. I make my recipes to spec, and I can’t possibly test out every variation.
There is no recipe in this link? Can you please update ????
Please click the big link that says “Please see my blueberry breakfast bars…”
I have not tried your recipes as yet but all look simply amazing. I just started on the Keto lifestyle so will be trying a few soon. I wanted to make these blueberry bars but the link is broken and not opening. Your site is very informative and so well put together. Thank you so much.
Thanks for the heads up… I’ve let Swerve know that something is up with that page.
I appreciate your recipes. I too spend lots of my time dreaming/thinking about food. I read recipes every day.
These blueberry bars are delicious. I splurged and added another half cup of blueberries. Keep up the good work!
I made these today and substituted butter flavored coconut oil for butter (I’m dairy free for a while). I also was a bit short of flaked coconut so I added crushed toasted pecans to get the full measure. They turned out fantastic! I’ll be making them again and again! Thank you!
I have a ton of blackberries, do you think this recipe would work or would it be too liquid?
Should be fine!
These were really yummy! The flavors developed a little more after the 1st day. Cured the sweet tooth! Thanks for the great recipe!
These are amazing, so satisfying. Thank you Carolyn!
I’m so glad I found your page! I used to have a blueberry breakfast bar that I made with oats for breakfast along with my husband. We would warm them and top them with yogurt. I missed the flavor and the morning routine, but now, thanks to you, we are once more having our routine again, but mine is Keto! I can only eat so many eggs in a week too.
