    Since developing this super popular and very easy basic quick bread recipe, we have been enjoying all kinds of keto-approved loaves of bread. But until now, no banana nut bread!

    After all, who would expect bananas to be enjoyed on the keto diet? Everyone who's been around keto for a minute knows that they’re generally considered a very big no-no.

    A lot of keto dieters are under the impression that bananas are off-limits and the only way to enjoy a slice of low-carb banana bread is to rely on extracts, which never taste quite as good as the real deal.

    Not this recipe!

    Why you'll love it

    Banana bread is so yummy. Moist, sweet, a little crunchy when you add in walnuts...it's like eating dessert for breakfast or a snack. There simply had to be a way to enjoy it even while eating low carb!

    This is seriously the best banana bread. It's absolutely delicious!

    Ingredients

    There are quite a few ingredients in this healthy banana bread recipe, but all of them play a very important role.

    ingredients for low carb banana bread.

    Bananas

    Authentic banana bread needs a banana, but you can still enjoy it and stay low carb. Using a real banana gives you that classic banana bread experience in taste as well as texture.

    Try to save your ripe bananas for this recipe!

    Fat and oils

    Add butter and coconut oil for the fats. This helps the bread stay soft and not too get crumbly or dry after baking.

    Eggs

    Eggs are a very important emulsifier.

    Flour

    I used both almond flour and coconut flour in this keto banana bread recipe. You'll also need xanthan gum to help it all stick together.

    Sweeteners and baking ingredients

    You also need the common baking ingredients salt and baking powder to make this bread.

    Sweeten the bread with both Stevia concentrated powder and another ½ a cup of your favorite low-carb sugar substitute!

    Nuts

    I prefer to use walnuts in banana bread. But, you can leave them out.

    Please note: Check out the recipe card at the bottom for a full list of ingredients used to make this low-carb recipe.

    Tips

    • Use a low temperature. Turn down the oven temperature a little and bake it for just a little bit longer. Don’t be surprised if you need more time in the oven than the recipe calls for. Simply keep the low-carb banana bread in until it passes the toothpick test and no longer has any soft areas. 
    • Make banana muffins. If you want it to cook up faster, another option is making banana muffins with a mix of almond flour and oat fiber. Mmmm - they are so good!
    • Turn this into mini muffins. Consider making these mini keto banana bread muffins, too. It's fun to have a basket of them out for the company to enjoy when you're ready for a treat.

    Instructions

    This is a very simple keto banana bread recipe. here's how to make it!

    Mix dry ingredients

    Use a medium bowl to mix together all the dry ingredients and then set them aside.

    Combine wet ingredients

    Use a food processor to combine the wet ingredients with the mashed banana.

    Mix it all together

    As you mix the wet ingredients with the dry, add the walnuts.

    Bake the banana bread

    Pour the batter into a loaf pan. Bake it until it is completely done.

    ️ Serving suggestions

    This is a wonderful recipe to make for your friends who aren't on the keto diet, too. They’ll never know this is low-carb banana bread. And maybe you can even win them over to eating better when they realize how delicious the food is!

    The moistness of the quick bread and the rich flavors of the banana and walnuts together make this a marvelous dessert or a great breakfast with your favorite cup of iced coffee!

    You can enjoy it hot if you like, but be aware that it will be extra crumbly. To serve it, let it cool completely first. To up the protein intake, add on a layer of your go-to nut butter!

    That's another reason to make it up as mini muffins instead of a loaf. You can sneak one right out of the oven and save the rest for later without making extra crumbles.

    Variations

    If you’re allergic to nuts or dislike them, simply leave the chopped walnuts out of your low-carb banana bread. While they provide additional protein and nutrition, there’s no need to include them if you don’t like the taste or can’t safely enjoy them!

    You could also add sugar-free chocolate chips to this banana bread. If you want it to taste like traditional banana bread, I suggest adding nuts.

    You can probably get away with using banana extract instead of mashed bananas like I did with my keto banana pudding. However, I suggest using real bananas because it will give you authentic banana flavor along with texture.

    FAQs

    Before we get to the recipe card, here are some questions people often ask about how to make almond flour banana bread. If you don't see your question in this list, please leave it in the comments.

    How do you store leftover banana bread?

    One of the great things about this quick bread is that you can make it up ahead of time. Simply let it cool completely before storing it.
    After it cools, wrap it tightly in plastic wrap or store it in an airtight container.

    It will keep at room temperature for a day or two, but it’s better kept in the fridge. If you keep it in the refrigerator, be sure to wrap it well and keep it airtight, so it doesn’t get soggy. It will last 3-5 days without issue.

    You can also make your keto banana bread ahead of time and freeze it. Just wrap your cooled loaves with plastic wrap and keep them in your favorite freezer containers.
    To serve, thaw them out the night before in the fridge.

    What are the health benefits of bananas?

    High in fiber - Fiber helps to promote a healthy digestive system and can aid in regulating blood sugar levels.
    Good source of potassium - Bananas are a great dietary source of potassium, which we all know is important for our electrolyte balance.
    Rich in vitamins - Includes vitamins B6 and C.

    How many carbs does a banana have?

    A medium banana has about 29g carbs. While this is clearly too many carbs to have as a keto snack when you’re eating low carb and trying to lose weight, it’s not bad when you add it to a larger recipe.

    Adding a single banana to this quick bread recipe will mean less than 2g of carbs per slice of bread. That's definitely reasonable! It's not like you'll be eating the entire loaf.

    So, while bananas are high in carbs, you can still enjoy them when you are using one banana for an entire recipe of gluten-free, keto-friendly quick bread.

    • Set aside.

    Notes

    Banana extract can be used in place of all or some of the banana to reduce carbs.

      I've made so many of your recipes Lisa, and this one didn't disappoint! I thought it was better than traditional banana bread. I used 5 eggs, following the other comments and suggestions, and followed the recipe exactly. I did add 1/2t of banana extract to make sure I had more banana flavor. It turned out perfect! Nutty flavor, great texture, absolutely delicious! I baked the loaf for 1 hour and it had nice crispy edges, and the center was cooked. I know this would freeze well, but we ate it all in a few days!

      I made this bread with 5 eggs (well, 4 but there was a double yolk), granulated Swerve, and Lily's dark chocolate chips instead of walnuts. It came out perfect! It was more of a pound cake like texture. Thanks so much for sharing this recipe. This is the first time I successfully baked a keto bread

      I love this recipe and bake it regularly but every time the loaf sinks after coming out of the oven! So disappointing. I’ve tried altering eggs, altering baking powder and a foil tent - all with no luck. Any suggestions appreciated!

      I love this recipe and make it every few weeks, often as muffins instead. However, when I make as a loaf, it sinks every time after coming out of the oven! Last night I tried a foil tent over the top while baking but that didn’t help. I have varied the amount of eggs with no change. Any ideas?

        Are you sure it's fully cooked when you're making it as a loaf? My bread is usually fairly dark on the outside when I take it out of the oven.

          I have made this twice. The first time I misread 3 T coconut oil and put in 1/3 cup. It was tasty, but like a greasy sponge and I had to try and mop the slices up with paper towel. 2nd time, I put in 2T coconut oil with the 1/2 cup of melted butter. It is still too much oil by a lot in my book. I used 4 big eggs, 2 T flax meal, 2 T water, 1.5 bananas`and added some cinnamon. Next time I will cut the butter by half and see how that works. Way too much fat though it tastes great.

          You can cut back on fat. It's added to make it more filling and to meet keto macros.

      I followed everything except I used 4 eggs and 3/4 cup of erythritol for the two sugars. Yuck. It was a sloppy, greasy mess. The flavor was nice so I will try it again without the coconut oil.

        I do have a sweetener conversion calculator that you can use. It's linked in every recipe. It depends on your own taste preference and would be anywhere from 1/2 to 1 cup.

          I’m asking because I assumed I could use erythritol for the sugar substitute although they are all different (Some sweeter than other and erythritol is not that sweet) but I also have to replace the stevia. I guess I’ll just take my chances then. It’s just expensive ingredients to replace if it doesn’t turn out right.

        • Lori

          April 15, 2020 at 1:20 pm

          And you don’t have monk fruit 50% extract powder no stevia extract powder on the conversion list.

          You can substitute it with about 2.5 to 3 tablespoons of a one-for-one sugar substitute like Lakanto Classic or Swerve.

      My wife just whipped one up. I'm a very well managed T1D with crazy low BMI, 6 foot, 175# and A1C of 5.9. We're very low carb and I owe my life to her. 6 years since diagnosis and I truly have never been healthier.

      Now, not only is this INSANELY good, here's a pro tip. Schmear a couple pats of Kerry Gold Irish butter on it hot. OMG good.

      She also wanted you to know that she used only Erythritol as sweetener, nothing else and only 4 eggs (which we all know are like Gold today...lol). It is moist, came outta the pan perfectly and this.... outs a TOTAL win! Thank you soooo much for the recipe.

      Insanely good. I don’t love eggy keto recipes and I’m cool with fruit so I used two bananas and only 4 eggs. I used a third banana and sliced it and pressed it into the top of the bread before baking. Used macadamia nuts instead of walnuts. The texture and flavor of the bread is so good. So dense and moist. By far the best banana bread I’ve ever had! Low carb and otherwise. Your recipes never fail me. Thank you!

      Woohoo - This pretty darn good. I probably left it in oven a few extra minutes - it was at 325 and done in about an hour ( not 70 minutes) so start testing when the smell fills the room. I am impressed with the smell and taste of the banana and walnuts. Of course the texture is a little bit rough as all low carb breads seem to be.

      Might use a little less sugar next time as I am not looking for super sweet in a banana nut bread. I used five eggs and left out the Xantham Gum. served it with a pat of butter.

      Thanks, for the recipe - it was a success and please post if you *actually made it* and have any tips.

      I tried your recipe because I needed to use up some bananas and have been trying to stay on a low carb diet. I really wanted it to work but all I ended up with was a pretty bread (in the oven) which flattened out about five minutes after taking it out of the oven. It tastes eggy and has a weird texture. What did I do wrong?

I am very new to keto baking, so I'm not sure if a longer cooking time or maybe more almond or coconut flour would help. Thanks!!

          Will toast the slices and then try separating eggs next time.
