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.

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.

Another winner!!! (Trying to think if I have ever made anything from.your site that I didn’t like. Nope. Love ’em all!!!!)
(I did make these bars with strawberries for 1/2 the pan and blueberries for the other 1/2.)
Really, really, really delish! TY!!!!!
praying for peace & provision in this season of sorrow
These bars are amazing! I doubled the filling because I had berries to use up! I also added lemon zest! Thanks for sharing all your creative recipe ideas! ❤️
Yummy!
Definitely going to try these. They look so good! Can I use arrowroot powder instead of the glucomannon or xanthum gum? That’s what I have on hand. Thank you!
Sorry, I don’t use arrowroot. I think you will need to experiment.
These only have 3.7 grams of protein, not enough for a breakfast for me. Could I add unsweetened protein powder to bump up the protein? How much? (I only gave it a 3-star because I haven’t made these yet.) I’ll update as soon as I make them.
Please do not rate my recipe if you haven’t made it. That low star count affects my ratings in Google, etc., and you won’t be able to come back and fix it. That’s not how it works.
This is not meant to be a protein breakfast.
I feel very honored to be the first review on these absolutely delicious bars. Recipe was super easy and they came out delicious. I do Keto, but the boys gobbled them up and had no idea. Absolutely a perfect thing to bring to a party, a picnic, or just to keep frozen in the freezer for a quick snack! Love them!!
These looked so yummy, I had to try them! So good, love the shortbread texture, takes me back to Mom’s baking! Next time, I’ll reduce the sweetener by 1/4, as they were a bit too sweet for my taste. Love your recipes, Carolyn.
Ooooh! These bars are scrumptious! I especially like the taste provided by the two sugars — brilliant! I saw this recipe this morning and knew I had to make it right away. It doesn’t take as long as the prep time seems. It went together in a very short time.
Made this for the first time today. Really easy to make and very tasty! I did double the blueberry filling and I’m glad I did. Required a fork to eat it, but the balance between the crust, topping and filling was spot on. Definitely will make this again! Thank you Carolyn for this and for all that you do!!

My family is not a coconut fan -what can I substitute ? Thanks for you help these sound delicious !
Please read the blog post, I already addressed this.
Really nice blueberry flavor – even with frozen blueberries. The crust was not overly sweet and I loved the addition of flaked coconut. But, then, I’m a sucker for coconut!
I’ve made the raspberry version of this, and will definitely be making this blueberry recipe. Blueberry is a family favorite!
Thank you for your incredible recipes! Each one has been delicious 😋
I have not tried these breakfast bars as of yet Carolyn, but they look absolutely magnificent!
I love blueberries anything! I will definitelybe trying these, you can bet on that. Thanks for sharing!
The recipe on swerve’s site calls for 1/4 cup xanthan gum…this can’t be right? Can it?
NO! It’s 1/4 teaspoon. Not sure what they are doing over there! 😉
Where is the recipe??
There is a link to it on the Swerve website.
The recipe no longer shows up with this link. I have used it several times, wonder what is happening, I know it’s not you.
Just search their website. They seem to have broken the links,
