This is the only Keto Banana Bread recipe you will ever need! Ground chia seed gives this bread the perfect texture with a fraction of the carbs. It has only 2.5g net carbs per slice!
It took me a while to perfect this Keto Banana Bread, but it was definitely worth the effort. After all, banana bread is very possibly the most comforting of baked goods. Who among us hasn’t had a grandmother or caring friend make us a tender loaf as a sign of their deepest affection?
And if you’re a mother, surely you’ve made numerous batches of banana bread for your own kids to let them know how much you love them.
Making this low carb version is definitely an act of love. All the more so because it won’t raise the blood sugar of you or your loved ones. Along with recipes like keto chocolate chip cookies and sugar free hot chocolate mix, baking up some Keto Banana Bread shows just how wonderful and caring you are.
Even if you plan to keep it all for yourself. After all, self-care is extremely important!
Why this recipe is so awesome
This recipe actually first debuted on my blog in May 2014. But I’ve recently updated it to make it easier and even lower in carbs. And I know you’re going to love it.
One of the things that makes this bread so special is that it really has a banana bread texture. But it contains no bananas at all! How is that possible, you ask?
The secret is ground chia seed. Chia seed swells up and and becomes a gel when mixed with water, and one day I realized that the consistency reminded me of mashed bananas. So I tried adding some to my keto banana bread.
Lo and behold, it added similar moisture and texture as real bananas. I was thrilled to pieces! Adding a little banana extract gave the bread just the right flavor too. And it has only 2.5g net carbs per slice.

“I made this no banana keto banana bread today, and it’s so moist and delicious. I love the addition of ground and soaked chia seeds that produced the tell tale black flecks mimicking those left behind by bananas to it look perfectly authentic.” — Diane K.
Ingredients you need
This post may contain Amazon or other affiliate links. As an Amazon Associate I earn from qualifying purchases.
- Chia seed: You will want to grind the chia seeds before mixing it with water. I recommend doing this in a coffee grinder or small food processor, as large processors don’t catch the small seeds as easily.
- Keto flours: I use a combination of almond flour and coconut flour for the right consistency and structure.
- Sweetener: I love Swerve Brown in this recipe, because I think it works well with the banana bread flavors. But you could use other sweeteners as well. Do keep in mind that allulose may make the outside of the bread brown too quickly.
- Protein powder: The addition of a dry protein like whey protein powder helps keto baked goods rise properly and hold their shape. You can also use egg white protein powder.
- Banana flavor: I recommend a natural banana extract rather than an imitation flavoring.
- Chocolate chips: I love the addition of keto chocolate chips like ChocZero in my banana bread but you can also mix in chopped walnuts, shredded coconut or blueberries.
- Pantry staples: Baking powder, vanilla extract and salt.
Step by Step Directions
1. Prepare the chia: Grind the chia seed in a coffee grinder or food processor. Transfer to a bowl and stir in the water. Set aside.
2. Whisk the dry ingredients: In a large bowl, whisk together the almond flour, sweetener, protein powder, coconut flour, baking powder and salt.
3. Add the wet ingredients: Stir in the eggs, melted butter, chia seed mixture, banana extract, and vanilla extract, until thoroughly combined. Stir in the water to thin the mixture to a scoopable consistency. If it’s still very thick, add more water, 1 tablespoon at a time.
4. Transfer to a loaf pan: Stir in the chocolate chips, if using, saving a few for the top of the bread. Spread the batter in a grease 8×4 inch loaf pan and sprinkle the top with the remaining chocolate chips.
5. Bake the bread: Bake at 350ºF for 60 to 75 minutes or until golden brown and the top is just firm to the touch. Let cool in pan 20 minutes, then run a sharp knife around the edges to loosen. Continue to let it sit in the pan until cool, about 20 minutes more
Expert Tips
This is an easy, family friendly recipe, but here are a few added tips:
There really is no good substitute for the chia. You can omit it but you will need to add additional liquid to the batter and the texture of the bread won’t be the same.
Mix the ground chia and water first, and let it sit for a bit while you work on the other ingredients. When you’re ready to mix it in, it should be like a thick, gelatinous paste.
How much additional liquid you need depends on the chia gel, as well as other ingredients like the coconut flour. If the batter is overly thick, add water a little at a time until it has a scoopable consistency. It should not be pourable.
Brands of banana extract differ in strength. I like the Olive Nation brand and find 1 ½ teaspoons to be right for a good banana flavor. Some baking emulsions or artificial flavors may be stronger, so stick with about 1 teaspoon.
Sweetener options: You can use your preferred sweetener in this recipe but there are a few things to keep in mind. Allulose tends to brown very quickly and your bread may become very dark, particularly on the sides touching the pan. You could try using a silicone loaf pan.
BochaSweet would work well in this recipe. You could also use a mix of sweeteners, such as Swerve and some liquid stevia or monk fruit extract. That can help reduce the erythritol and minimize any aftertaste you may experience from either sweetener.

- In a large bowl, whisk together the almond flour, sweetener, protein powder, coconut flour, baking powder and salt.
- Stir in the eggs, melted butter, chia seed mixture, banana extract, and vanilla extract, until thoroughly combined. Stir in the water to thin the mixture to a scoopable consistency. If it's still very thick, add more water, 1 tablespoon at a time.
- Stir in the chocolate chips, if using, saving a few for the top of the bread. Spread the batter in the prepared pan and sprinkle the top with the remaining chocolate chips.
- Bake 60 to 75 minutes or until golden brown and the top is just firm to the touch. Let cool in pan 20 minutes, then run a sharp knife around the edges to loosen. Continue to let it sit in the pan until cool, about 20 minutes more.
Amanda says
Where and what protein powder do you use please ?
I’ve seen it used in a few recipes, but have no idea where to buy and what it exaclty is ?
Roze says
This was the most INCREDIBLE banana bread ever!! I have to make another tonite, we devoured it in my house.
Courtney says
Hello,
I would love to try this recipe but I don’t have any chai seed or flour. Is there a substtittue you can recommend? I do have golden flax flour if you think that would work or just more almond flour.
Thanks in advance!
Carolyn says
I’d do the flax, probably.
Sandra says
hello Carolyn
I am from Australia and have had a few problems finding some of the ingredients for this recipe. Firstly, Swerve doesn’t seem to be available in this country, so i tried using Stevia instead, but this tends to leave a bit of an after-taste which i don’t particularly like. Could i rather substitute with Coconut sugar – this has a much more natural sweet flavour i think.
Also I could only find Almond meal/ground almonds which the lady assured me was the same as Almond flour but i see one of your comments says it is definitely different. I have read your explanation on Almond Flour and see that the difference is in how much finer ‘flour’ is than ‘meal’. Is there any way of grinding Almond meal finer to make it into flour as there doesn’t seem to be anywhere here to actually buy the flour??
I also couldn’t find any Stevia extract or Banana extract. I will have to keep looking but wondered if i could just add a bit more coconut sugar instead of the Stevia?
I am quite new at this game as you can probably see! 🙂
Thanks
Carolyn says
Well, coconut sugar has carbs so if you’re low carb, I would choose something else, like regular erythritol or xylitol. I have plenty of Australian readers who use these things. You could try grinding the almond meal further in a coffee grinder. You can add more of another sweetener in place of the stevia extract.
Tiffany says
I make this bread all the time and it’s awesome and I can’t thank you enough for it.
I just tried it with corn extract instead of banana and it’s good! Doesn’t taste like cornbread plain, but with butter on it it is just like corn bread!!
maggie says
Have you tried making this with the THM Baking Blend? And, if so, how much would I sub (assuming i would sub for the almond & coconut flours & the whey)?
Carolyn says
Sorry, I haven’t tried it with that yet and can’t really give you any guidance.
Debra says
Just made this today. Love it. So good, I feel guilty for eating it…NOT! Would love to add some walnuts or pecans next time!
Deborah says
Just made this to have take along breakfast to eat at work. But could not wait, had to have a slice.
Absolutely wonderful. The ground chia seeds are genius. They really do mimic the texture of mashed banana in the bread.
I did add two handfuls of roughly chopped walnuts as that is they way I used to make my banana bread pre low carb. Just great.
I also browned my butter before adding to give it another layer of toasty flavor. I think it worked well.
Thanks Carolyn. Can’t imagine doing low carb without the wonderful baked goods you have give us all.
Diane says
Made this yesterday, and it was a total winner!! Taste, texture, everything. Instead of Swerve in the frosting I used some Torani sugar free salted caramel syrup and a few drops of liquid sucralose. Can’t thank you enough – I really missed banana bread!!!
Carolyn says
So glad you liked it!
Holli says
Carolyn, this recipe sounds great. After years I have found that liquid splenda works the best for my taste and diet needs. Do you think it would work to use unsweetened coconut to substitute for the swerve in your recipes? For example, using the coconut in place of the swerve in this recipe and using drops of the liquid splenda? I just don’t know what else I could use to replace the swerve besides the granular splenda and I’d rather not. Thanks for your advice. Your recipes are so awesome!
Carolyn says
I wouldn’t replace it cup for cup, I’d maybe just do a few more tbsp of either almond flour or coconut and then sweeten to your liking with the liquid sucralose. For the frosting, the cream cheese gives it structure so you should be fine there.
Anne-Marie Keightley says
Is your almond flour real flour OR ground almonds. Very different things.
Carolyn says
Yes, I know that. It’s real almond flour. You should check out my baking tutorial. https://alldayidreamaboutfood.com/2013/02/low-carb-basics-baking-with-almond-flour.html
Emily says
Okay, I was skeptical about this recipe, but can I just say “wow!!!” Delicious, and it even looks like banana bread because of the chia seeds.
I love your website. We don’t have diabetes, but my daughter was born with neurofibromatosis which causes a host of problems. We were trying to eliminate her focus issues by going gluten free, and while it didn’t solve that problem, her acid reflux is nearly gone. I love that she can enjoy treats made with almond and coconut flours and not miss the gluten-filled ones. Thank you for all of your hard work!
Laura F. says
HELP! I just made this and I don’t know what I did wrong! It came out very moist but extremely bland with no banana flavor at all. Should I try doubling the banana extract?
Thanks!
Carolyn says
Sounds to me like the banana extract isn’t strong enough. I don’t know what brand it is but yes, definitely up the amount!
Dee says
Hello,
Sorry if this is a silly question but is banana essence the same as banana extract and will it work for this recipe?
Thanks!
Carolyn says
I think so, yes.
Cecelia says
What can I use instead of stevia extract. I don’t have snt of that and I don’t know where to buy it.
Carolyn says
Use a little more swerve or other erythritol, I guess.
Cecelia says
I was ready to make this the other day and my husband looked at the recipe and said he did not like banana bread so can I use something else like maybe lemon.
Carolyn says
Sure, use whatever extract you like best.
Jackie says
I made this today and it was perfect…even my non low carb husband has eaten 2 pieces! I used 3/4 cup water for chia seeds and egg white protein instead of whey protein baked for 1 hour 15 minutes. I think it may even taste better cold…Thanks for such a great recipe!
Cecelia says
Can I use gluten free flour instead of almond flour. I have tried all the stores around here and no on carries it. I bought slivered almonds and someone said I have to be very careful because I could be making almond butter if I mix it too long.
I have everything except the almond flour.
Carolyn says
I think the amounts of other things will change some, because gluten-free flour is drier than almond flour. Start by not putting in any almond milk and then see how your batter is. If it’s REALLY thick, add 1/4 cup, then maybe a tbsp or two more. It should be spreadable but not pourable, if that makes sense.
Anna says
This is baking right now! Can’t wait! Would you recommend storing in the fridge or on the counter?
Carolyn says
I wouldn’t store it on the counter for more than about 2 days.
Stacy says
I made this yesterday and added 1 cup chopped walnuts. The texture of the bread is spot on! And the icing is just divine!! I am enjoying a piece right now for breakfast. I never thought eating banana bread would be a part of my low carb diet. Thank You Thank You Thank You!! You are a genius.
Carolyn says
So glad you like it!
Vivian says
Wonderful recipe and I am so thankful for your work to create it! Thank you!! I have it in the oven and it smells great. (tasted great before I baked it so I am sure we will love it!) 🙂
