This low carb keto banana bread recipe is one of my favorite keto recipes to share with family and friends… and then you can tell them AFTER that it’s actually a sugar free banana bread! No one can ever tell the difference, thanks to a mix of low carb flours, a high-quality natural sugar substitute, and an easy swap for the bananas. Simply mix up the almond flour banana bread batter, bake it, and then let it cool (truly, the hardest part!).
Enjoy with a bulletproof coffee or keto Starbucks drink for the ultimate morning meal. And if you like keto banana recipes but prefer a more portable version, try keto banana muffins instead.
This keto friendly banana bread uses a blend of premium low carb flours to get the right density and moistness in your loaf, like the real thing. Sometimes you really need to use a blend of flours to get that “just right” texture, and this is one of those times. The wet/dry ingredient ratio is important here because that’s what ensure the right texture. Wholesome Yum Blanched Almond Flour and Wholesome Yum Coconut Flour are both super finely milled and create the perfect consistency.
And, we’re using Besti sweetener for this bread, because not only does it taste just like sugar (without sugar alcohols!), it also helps to seal in moisture so your bread won’t be dry. Other sweeteners won’t do that!
Is Banana Bread Keto?
Traditional banana bread is not suitable for keto, as it’s made with white flour, sugar, and bananas. This low carb banana nut bread recipe is keto friendly.

Almond Flour Banana Bread Ingredients
This section explains how to choose the best ingredients for keto banana nut bread, what each one does in the recipe, and substitution options. For measurements, see the recipe card below.
The dry ingredients:
- Wholesome Yum Blanched Almond Flour – The BEST almond flour that’s blanched and finely ground for the best texture in keto baked goods. Make sure you use a finely ground almond flour instead of almond meal, or it will change the texture of the bread.
- Wholesome Yum Coconut Flour – Made with premium organic coconuts with a super fine texture, this works best in baked goods.
- Spices & Leavening Agents – Including baking powder, cinnamon, and sea salt for perfect flavor and bread-like feel.
- Xanthan gum – This gives low carb and gluten-free baked goods a more traditional texture.
- Chopped walnuts – Optional, but adds great texture and flavor. See below for other add-in options!
The wet ingredients:
- Butter – Use grass-fed for best flavor and nutrition, but any unsalted butter at room temperature will work. See below for a dairy free variation.
- Besti Monk Fruit Allulose Blend – This is the best sweetener for keto quick breads like this one, not only because it sweetens like sugar but most important, it keeps them super moist. If you have to, you can substitute another keto sweetener, but the end result may be more dry.
- Eggs – Use large eggs and make sure they come to room temperature before using them in the recipe. If you forgot to do this, you can place them in warm water for a few minutes to come to room temperature faster.
- Almond milk – You can use store bought or make your own homemade almond milk, but either way, make sure it’s unsweetened. You can also use other keto milks, such as coconut milk beverage or watered-down heavy cream.
The secret ingredient:
So what’s the secret to this keto banana bread recipe? Have you figure it out yet?
You guys, this is like the best stuff ever. You can make a truly low carb banana bread recipe and it still tastes like bananas!
Extracts are the secret ingredient to make almost any high-sugar or high-carb food possible again on a keto diet.
And just to clarify, I’m not talking about those artificial “imitation” extracts. You do not want those! This extract is derived from real bananas and it lasts a long time.
How To Make Keto Banana Bread
This section shows how to make easy keto banana bread with step-by-step photos and details about the technique, to help you visualize it. For full instructions, including amounts and temperatures, see the recipe card below.
- Mix dry ingredients. In a large bowl, mix together Wholesome Yum Almond Flour, Wholesome Yum Coconut Flour, baking powder, cinnamon, xanthan gum, and sea salt.
- Beat butter. In another large bowl, beat butter and Besti Monk Fruit Allulose Blend until fluffy.
- Mix wet ingredients. Beat in the eggs one at a time, until smooth. Then, beat in the almond milk and banana extract.
- Combine. With the mixer on medium, gradually add dry ingredients into the wet ingredients, until thick and uniform.
- Stir in nuts. If you’re adding walnuts, stir some in, reserving some more for the top.
- Transfer. Scoop the batter into a small loaf pan (this one is the perfect size) lined with parchment paper, including the sides. Smooth out the top. Sprinkle with more walnuts and press them lightly into the surface.
- Bake sugar free banana bread. Bake until the top is golden, then tent the top with foil and continue baking until it passes the toothpick test (an inserted toothpick should come out clean).
- Cool. Let the bread cool completely before slicing.
Tips For The Best Low Carb Banana Bread
Follow these tips for perfect banana keto bread, each and every time.
- Use fresh baking powder. Keto banana bread doesn’t rise very well, so fresh baking powder is especially important to help it rise as much as possible.
- Use xanthan gum. Add 1/2 teaspoon into the dry ingredients and your banana bread made with almond flour will have a better texture. Plus, it will be less crumbly.
- Use room temperature ingredients. This will ensure a smooth batter that doesn’t clump.
- Round the top. Since it doesn’t rise much, shaping the batter by rounding the top is going to help your low carb banana bread recipe look more traditional.
- Consider coverting it part way through baking. Keep an eye on your bread as it bakes. If the top of the bread starts to brown but the inside is still moist, you can tent the top with foil and then continue the cooking time.
- Let it cool completely. I know it’s hard, but it’s important to be patient and let the gluten free sugar free banana bread cool completely on a wire rack before slicing, or it will fall apart.
Keto Banana Bread Variations
- Dairy free – You can make this low carb banana bread recipe dairy-free if you need to, by replacing the butter with coconut oil. If you’re sensitive to dairy but can handle ghee, that’s a better option if possible. Since the recipe calls for creaming the butter, the end result will be a little different, but it will still work!
- Coconut free – If you can’t have coconut, you can try replacing the 1/4 cup coconut flour with 3/4 to 1 cup almond flour, and check the consistency against the pictures to make sure it’s similar.
- Nut free – Unfortunately, I don’t have a good nut free suggestion here; sunflower seed flour might work to replace almond flour, but I haven’t tried it and the texture will likely be worse. It’s fine to replace almond milk with another keto milk, though.
- Chocolate chip – Fold some sugar free chocolate chips into the batter before baking.
- Blueberry – Fold some fresh or frozen blueberries into the batter.
- Chocolate – Replace 1/4 cup of the almond flour with 1/4 cup cocoa powder.
- Caramel topping – Drizzle your finished keto banana bread with sugar free caramel sauce.
- Maple glaze – Make the perfect fall inspired glaze by whisking together heavy cream, a little keto maple syrup, and powdered Besti to thicken, then drizzle on the cooled bread.
- To store: It will be fine for 2-3 days on the counter, and you can keep it in the fridge for up to 1 week. Wrap in parchment paper instead of plastic, so that it doesn’t collect too much moisture and get soggy.
- To freeze: Let the banana keto bread cool, then slice it up and freeze the slices. You can do this in a single layer on a parchment lined baking sheet, then transfer to a freezer bag once solid. Or, you can freeze in a bag right away if you place pieces of parchment paper between the slices. Both of these methods prevent the slices from sticking together, so that you can take them out one at a time as needed.
- To thaw: Thaw on the counter or in the fridge overnight.
- To reheat: If you like warm banana bread, reheat gently in the microwave or the oven.

Just made this, and it taste just like regular banana bread. It’s moist and tender. I made my family regular banana bread and I was feeling left out, so I looked on wholesome yum and found this recipe. I haven’t found a recipe I did not like so far. 😋
This banana bread is excellent and just what I needed! I love dessert and have tried other baked Keto recipes from different sites, but they just didn’t hit the mark. This bread is delicious with butter or plain. It doesn’t feel like I’m not eating Keto! This is a very well done recipe. Keep them coming! I’m now following! Thank you!
I made this recipe with a few small changes. I added two mashed bananas instead of the extract; I didn’t have any and I’m not solid Keto. I also subbed arrowroot for the Xanthan gum because I didn’t have any.
I must say that this bread is pretty darn good. I tried several gluten free breads and this one is my favorite so far.
Did you add extra flour or omit any other ingredients or just the extract? I was thinking of doing the same thing since I am not full on keto either.
This was so delicious but way too wet. Not sure if my brand coconut flour didn’t absorb well. How much almond flour could I replace the coconut flour with? I used 3 eggs instead of 4. Any idea what it could’ve been?

Hi Lorraine, Coconut flour and almond flour aren’t interchangeable. I suggest trying Wholesome Yum Coconut Flour.
I used one TBSP banana extract and I am glad I did. The last time I did keto it was so strict I didn’t have any of this good stuff. I really hope it doesn’t knock me out of ketosis or counting carbs isn’t difficult. I got a blood ketone meter hopefully this helps. I just wanted to say thank you so much for the recipe its nice to have a treat now and then and I expect this will freeze up well so I don’t eat the entire loaf lol.
I made it with 1/2 cup chopped walnuts and a cup of halved cranberries and used orange extract instead of banana. It turned out great!!! The texture was more was more cake like than my cranberry bread but it’s delicious. Everyone loved it.
Hi, I hope, with your help, to be able to adjust this recipe so that I can add halved cranberries and exchange the banana flavoring for vanilla or orange so that the result is my traditional cranberry nut bread. My recipe also has orange juice and grated orange peel, but I could omit the juice, I think, without much change in flavor. My recipe has cup of halved cranberries in the dough which has 2 cups of flour. What amount of berries do you suggest I try? Your bread also has twice the nuts. I have your cookbook and really enjoy it. Your.recipes are so easy to follow! thank you!
Wholesome Yum D0
Hi Barbara, Unfortunately, I have never tried this, so I don’t have much insight. You could possibly use the same amount of nuts and cranberries as your original recipe.
I love banana bread so much and I’m so thankful for this delicious recipe. I know it says cool before cutting but I was wondering how long is best to let it cool? Thank you I’m advance! Keep up the good work Maya!

Hi Jenn, Let the bread cool completely, or it will most likely fall apart when you slice it.
So so delicious! This is my go to recipe for banana muffins. Thanks!!
This bread is so delicious!!! I would have never thought of using the banana extract and taking out the bananas. I just made it for the family and everyone really liked it!! It’s so good that they never would have known it was keto style bread!! I want to find a recipe for the bread machine, or can I use this one?? Hmm…I am going to try it!! THANK YOU FOR SHARING!
I am mostly keto, some days low carbish. But I made this Banana Nut Bread yesterday and my non – keto husband liked it! I will probably back off on the cinnamon to 1 tsp though when I make it again. Great recipe & Simple. Thank You.
I am so thankful for these recipes. They are fantastic.
I decided to put banana but sliced it in chunks so people on the keto diet could remove it. It gives it more flavor and moisture. I do not have coconut flour but I added 1/2 cup more almond flour. I do not have almond milk, I used coconut milk and vanilla extract since I do not have banana extract. It is delicious and moist. Fyi, it took approx 1 hour ten minutes since my oven temp is off. I flip it down since top sunk a bit while cooling and it fixed the sunken top. Do cover with foil if browning too fast on top. Thanks for sharing.
Can I use the ripe banana instead of banana extract?
Wholesome Yum D0
Hi Littymol, Using a banana would change the moisture in the bread + it would no longer be low carb.
Definitely have to get use to the texture and flavor….did not add xanthan gum..
Maya | Wholesome Yum0
Hi Carla, The texture is better with the xanthan gum, so try adding that in next time.
Exceptional taste and texture. No one would ever know this banana bread was low carb! Surprised anything could taste so delicious and yet be so easy to make. I’ll absolutely need to freeze individual slices immediately or I’ll be tempted to keep nibbling away.
Great and easy recipe!
Unfortunately, I don’t have a loaf pan. What can I use alternatively until I decide I like the recipe enough to purchase one?
Wholesome Yum D0
Hi Kelly, You can also make this recipe into muffins.
It was delicious! Will make it again,thank you so much for the recipe ❤️❤️
Hi! Are there any alternatives I can use if I don’t have xanthan gum?
Wholesome Yum D0
Hi Kay, Psyllium husk powder might work, but you’d need a few times more of it. The xanthan gum is also an optional ingredient so you can just omit it, too.
