Free Printable: Low Carb & Keto Food List
Get It NowMy keto banana bread recipe is hands-down one of my favorite keto recipes to share with family and friends… especially because no one ever realizes it’s low carb! I wait until after they’ve raved about it to tell them it’s actually sugar-free. Between the perfect blend of low carb flours, a high-quality natural sugar substitute, and an easy banana swap, it tastes like the real thing. Bake it with me for the best low carb banana bread you’ll ever have!
Why You Need My Keto Banana Bread Recipe

- Real banana flavor – With a secret ingredient, my keto banana bread actually tastes like it has bananas in it! Nobody will know it doesn’t. 🤫
- Moist, cake-like texture – Sometimes you need a blend of flours to get that “just right” texture, and this is one of those times. I love how moist this low carb banana bread turns out.
- Quick and easy – Just 15 minutes of prep time! Mix up the batter, pop it in the oven, and you’re set. Waiting for it to cool is the hardest part.
- Low carb & keto friendly – With just 2 grams of net carbs per slice, this bread fits perfectly into your gluten free or keto lifestyle. I love it with a bulletproof coffee or keto Starbucks drink to start the day!


Ingredients & Substitutions
Here I explain the best ingredients for my low carb banana bread recipe, what each one does, and substitution options. For measurements, see the recipe card.
Low Carb Flours:
My keto friendly banana bread gets its perfect texture by blending Wholesome Yum Blanched Almond Flour and Wholesome Yum Coconut Flour, and this works much better than using one of them alone.
The brand of flours you use can also make a difference, because many brands of almond flour are too coarse (read: gritty texture, ugh!), and some brands of coconut flour absorb too much or not enough moisture.
Can you substitute the almond flour or coconut flour?
If you can’t have coconut flour, swap it with 3/4 to 1 cup of extra almond flour. Unfortunately I don’t have a great swap for the almond flour in this keto banana bread, but sunflower seed meal might work.
Sweetener:
The sweetener you use makes a difference! I use this Besti sweetener. Not only does Besti taste just like sugar with zero net carbs, it keeps the bread moist. Other sweeteners (including erythritol, and most brands of monk fruit and stevia) won’t do that, so the texture will be more dry with those.
My Secret Ingredient:
Have you guessed what it is yet? 🥁 It’s banana extract! Seriously, this stuff is amazing — you get all the banana flavor without the carbs. And don’t worry, I’m not talking about artificial extracts here.
I use and recommend this one, made from real bananas. Many brands in stores have an artificial taste or are less intense, so keep in mind the amount you need can vary if you use a different brand.
If you’d rather use real bananas, try my almond flour banana bread instead. It’s higher in sugar due to the bananas, but has no other sugar added.
Other Ingredients:
- Unsalted Butter – I like this grass-fed brand. For a dairy-free option, swap with coconut oil or ghee. Since my recipe calls for creaming the butter, the end result will be a little different, but it will still work.
- Eggs – You can probably substitute flax eggs, but your low carb banana bread will be more fragile with them.
- Almond Milk – Whether store-bought or homemade almond milk, just make sure it’s unsweetened. You can also use other keto milks, like coconut milk beverage or watered-down heavy cream.
- Spices & Leavening Agents – Baking powder for lift (don’t use baking soda!), cinnamon for flavor, and sea salt to balance the sweetness.
- Xanthan Gum – I use this brand. It acts like a binder, so your keto banana bread doesn’t crumble apart, and improves the texture.
- Add-Ins – I add chopped walnuts for crunch. You can also use sugar-free chocolate chips (I like this brand), blueberries, or other nuts or seeds, like pecans, almonds, or pepitas.

How To Make Keto Banana Bread
I have step-by-step photos here to help you visualize the recipe. For full instructions with amounts and temperatures, see the recipe card.
- Mix the dry ingredients. In a large bowl, mix together the flours, baking powder, cinnamon, xanthan gum, and sea salt.
- Cream the butter. In another large mixing bowl, beat the butter and Besti sweetener with an electric mixer, until fluffy. I have this hand mixer and love the multiple speeds, plus convenient storage.


- Add the other wet ingredients. Beat the eggs into the creamed butter, one at a time, until smooth and creamy. Then, mix in the almond milk and banana extract.
- Combine the wet and dry ingredients. With the mixer on medium speed, gradually add the dry ingredients into the wet, until thick and uniform.


- Fold in your add-ins. If you’re adding walnuts or any of my add-ins below, stir some in. I recommend reserving some of them for the top!
- Transfer the batter to a lined loaf pan. I use this one and it’s the perfect size. Smooth out the top. Sprinkle extra nuts on top and gently press them in.
- Bake until golden. Then, tent the top with foil and continue baking until a toothpick comes out clean. Let your keto banana bread cool completely on a wire rack before slicing.


My Recipe Tips
- Use fresh baking powder. Low carb baked goods don’t rise as well as traditional ones, and this “batter” is pretty heavy, so this is extra important.
- Use room temperature ingredients. Your butter won’t cream properly if it’s cold, and it can solidify if your eggs or milk are cold. If you forgot to set them out, here are my tricks to bring them to room temp faster:
- Eggs – Pop them in a bowl of warm water for a few minutes.
- Milk – Heat in the microwave for 10-15 seconds. Just make sure it’s not actually hot.
- Butter – Fill a stainless steel bowl with boiling water. Let it sit for a few minutes, then empty, dry, and place upside down over your butter. It works faster if you cut the butter into pieces first.
- Round the top. Since keto banana bread doesn’t rise much, you’ve got to round it before baking if you want that classic bread shape.
- Baking time can vary. Keep an eye on it and cover once it’s golden. And don’t forget to use a toothpick to check when it’s done — it should come out clean.
- Don’t skip the cooling. I know it’s tempting to slice right away, but waiting for it to cool completely will keep it from falling apart and improves the texture.
- Want to add a glaze? Drizzle your low carb banana bread with my sugar free caramel sauce, or make a maple glaze by whisking together heavy cream, my Wholesome Yum Sugar Free Maple Syrup, and powdered Besti.
- Prefer to make muffins? My keto banana muffins are based on this keto banana bread recipe.

Maya’s Recipe Notes
Serving size: 1 slice, ~3/4 inch thick
- Tips: Check out my recipe tips above for the right batter texture and loaf shape, and glazes you can use on top of your keto banana bread.
- Store: It’ll keep for 1-2 days on the counter, or up to a week in the fridge. Wrap it in parchment paper (not plastic wrap), so it doesn’t get soggy.
- Reheat: If you like it warm, just microwave a slice for about 15 seconds.
- Freeze: You can freeze this bread for up to 3-6 months. I like to layer parchment paper between slices, so you can grab one at a time. Thaw in the fridge, or just microwave with a little butter.
