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.

“Made this yesterday and, WOW, I love it!! I followed the recipe exactly and am so happy with the flavor and texture, especially the outside has a bit of a sweeter taste and crust. Thanks, Carolyn!” — Karen L.
“By far the best tasting banana bread recipe that I’ve ever made! Know one believes it was made without real bananas!” — Susan M.
“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.

- 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.
Deb says
Carolyn, I’ve been craving bananas lately and was thrilled to see a recipe that would allow me to indulge! I wanted to make muffins, but will these (minus the frosting of course) be able to be kept in the freezer? Thank you for all of your wonderful recipes : )
Carolyn says
Yes, these would freeze well. I didn’t do it myself, but I am almost positive that they would.
Cecelia says
I could not find ground chia seeds so I got chia seeds with flex in it. Can I use that and does it still need to be ground? Can I use the little grinder I have? Will the chia seeds with flex in it or should I just get the chia seeds?
Cecelia says
Just me again. Will the chia seeds with flex change the taste?
Cindy says
Hi Cecelia,
I think it is important to the texture of the cake to have the chia seeds ground up otherwise the little seeds have a tendency to pop when bitten on in a cake/muffin when they are not ground. And the ground chia seeds is what is supposed to mimic the mashed banana. And the flax will most likely change the flavor a bit. It has kind of an earth taste to it. But then again the Banana extract may mask the taste of the flax but the flax will make the cake a bit more grainy, like the texture of a bran muffin.
Cecelia says
Thanks again.
I think you need your own T.V show.
Thanks again
Carolyn says
You can grind them yourself…that’s what I do, in a coffee grinder. I think it will be okay.
Anne O says
Carolyn, I followed all of your directions to a “T” EXCEPT for cooling it off before cutting- not a chance. Within 1 minute, I cut a fat slice, smeared on some of the icing, and almost suffered a heart attack. It was so delicious. Beyond anything anyone has described. Excellent and thank you for taking the time to perfect the recipe….it shows. I’m 3 months into low carb cooking & baking and you are a daily resource of mine. I’ve made 7 of your recipes, all are keepers. Many, many thanks for your work! Please don’t leave us or retire 🙂
Carolyn says
Glad you liked it that much!
Barb Sacco says
Carolyn, if I wanted to make this into muffins instead of a loaf, how much time and at what temp should I bake them? I’ll assume the standard fill of 3/4 on the muffin liners would do? Cupcakes are easier to do for fund raisers than sliced breads are. Thanks for all your wonderful, healthy recipes!
Carolyn says
Bake them at the same temp and I think they will take at least 25 minutes. But I would start checking them after 20 minutes and keep checking every few minutes after that.
Barb Sacco says
That sounds right to me, too. Thanks so much!
Lori says
Did anyone try muffins?
Deb says
Lori, I’ve never actually made the bread just muffins and the are delicious and freeze wonderfully!
Cindy Maddux says
Made this basic cake yesterday (minus the frosting) and had to make a few changes to it because I didn’t have banana extract, unsweetened almond milk or unflavored whey protein. I had coconut extract, unsweetened coconut milk and vanilla flavored whey protein powder (Body By Vi) and so I used them, also omitted the vanilla extract.
The cake is super moist and dense thanks to the ground chia seeds, which I did have to use close to the full cup of water to get the mashed banana consistency. I had some fresh strawberries that I had been marinating in a sugar substitute and it made a little syrup with the strawberries and I made some whipped cream all to put on top of a slice of cake. It was so delicious, very tropical.
I just love your recipes and appreciate, very much, all of the work you put into perfecting them. And the stories you include with them are so entertaining.
Thanks for mentioning that you used your coffee grinder to grind the chia seeds. I had one in the very back of a cabinet that I had completely forgotten about so I dug it out and it worked perfectly. It’ll go back into the cabinet but up front rather way in the back. I’ll have to try it to make the powdered sweetener (from the granular form) for the frostings.
Carolyn says
Your changes sound good too!
Gerri says
Fantastic! Yes, the best banana bread recipe ever. Texture, flavor were perfect. I added 1 cup chopped walnuts & will use 1 cup water for the chia seeds next time. Mine was also like a paste with 1/2 cup water, but it still turned out utterly delicious. Thank you for returning the yummy aroma of banana bread baking to my kitchen.
Carolyn says
So glad to hear it!
dina says
it looks great!
Charlotte says
I lot of your baking recipes call for whey protein. Is there a good substitute for it?
Carolyn says
Hemp protein or powdered egg white. It’s not about a dietary supplement, it’s about getting a dry protein to replace the gluten (which is a protein). It helps it rise and hold its shape.
Melissa says
Would vital wheat gluten work as a substitute for the whey protein?
Carolyn says
Sorry I really cannot guide you as I haven’t tried it.
Anne-Marie Cain says
This looks sooooooo yummy! What size loaf pan did you use? Can’t wait to give it a try! 🙂
Carolyn says
The standard size 9 x 5 inches.
Me says
Is the amount of water in the recipe correct? It made a really thick paste for me, not really a jell. It’s baking now- can’t wait to taste it! Thanks for sharing your creations 🙂
Carolyn says
I believe it is, although it’s possible I wrote it down wrong. It should have been the consistency of mashed bananas. Let me know if it doesn’t turn out properly…I will test it again. My kids won’t complain!
Laurel Otto says
Why are there no bananas in the banana bread?
Carolyn says
Because it’s keto and bananas aren’t a good choice.
Katrina @ In Katrina's Kitchen says
So so killer! Love this one, my friend!
Carolyn says
Thanks, lovely lady!
Cecelia says
Makes sense. Sorry about that.
Carolyn says
No worries. If you are looking to sub in sugar, you can put in about the same amount I use Swerve.
Cecelia says
Why dos.t any recipe have the amount of sugar?
Carolyn says
Because I don’t use sugar.
Jeanette | Jeanette's Healthy Living says
So great to finally meet you in person at BlogHer Food Carolyn!! Hope we get to see each other again soon – wish I could have stayed longer. Love this banana bread with chia seeds, almond flour and coconut flour.
Carolyn says
You too, Jeanette!
Jasmine Lukuku says
I would like to see your birth certificate, because I’m pretty sure you were built in some bio-technical lab where they make bionic superwomen.
I love reading a recipe and realizing that I have every ingredient on hand. When that happens, I know it’s meant to be. It looks like I have some banana bread to bake!
Carolyn says
Okay, at first I thought this had to be spam, with the birth certificate comment. Thanks for the giggle, Jasmine!
Jocelyn (Grandbaby Cakes) says
This looks absolutely fantastic! That frosting is amazing!
Karen says
Can anything be substituted for the whey protein powder
Carolyn says
Please read the tips section, you will see I give alternatives.
Jessica @ A Kitchen Addiction says
It doesn’t get much better than banana bread straight from the oven! Love this caramel frosting!
Lin says
I’m making this today! My hubby is insane for banana bread. BTW, we are also crazy about your delicious chia seed brownies!
Carolyn says
Thanks, Lin!
Christine from Cook the Story says
I can almost smell the goodness through the computer!
Regan @ Cabot Creamery says
I swear May is the new December. Deanna from Teaspoon of Spice Blog and I were just talking last week about how crazy busy May has all of a sudden become.
This recipe is genius by the way. Can’t wait to try the chia concoction.
Question — and we can discuss this in VT this weekend 🙂 but how does your family do with Swerve? I love it and think it’s genius. I’m just hesitant with my family to see if they can taste the difference.
Carolyn says
My kids are great with it. My little one tends not to like it in frostings that don’t contain chocolate, for some reason, but the other two are fine with it in anything. And the little ones likes it in almost everything else.
DEBRA GILBERT says
Can I use 1/2 heavy cream and 1/2 water as a sub for almond milk?
Carolyn says
Yup, that’s perfect.
Sasha says
Can I use heavy whipping cream as a substitute for all of the water and almond milk?
Carolyn says
It will make the batter much too thick. You can water it down, though.
Nancy says
Where is almond milk in the ingredients list?
