Finally! A sweet and delicious keto banana bread recipe.
This recipe has tons of banana flavor, chopped nuts, and a moist, tender crumb.
Just like Keto Chocolate Muffins, Banana bread is perfect as a keto breakfast bite, or a sweet nighttime snack that won't ruin your meal plan.
WHY YOU'LL LOVE IT
Big Banana Flavor - One banana goes into the recipe, but we're also adding banana extract, to ensure that all of the banana flavor you want is here in your keto banana bread.
A Sweet Breakfast or Snack - Banana bread is versatile. Enjoy it on your way out the door in the morning, or have a piece with your afternoon coffee.
Easy Quick Bread Recipe - This bread requires no yeast, and just a few common keto baking ingredients to whip together. If you've done any low carb baking, you probably already have everything you need.
There are only 5 net carbs per serving of this keto banana bread.
INGREDIENTS NEEDED
Eggs: 4 whole eggs ensure that this recipe is protein-heavy. They also add moisture to the batter and hold the whole loaf together.
Banana: Using one instead of 2 or 3 lets us keep the carb count low. Use a ripe banana that is starting to turn brown, and mash it up with a fork.
Unsalted Butter: Melt the butter before mixing up the batter, and let it cool down slightly. Adding hot melted butter to the batter will start to cook the eggs, so try to avoid that.
Vanilla Extract: The prevailing flavor in most baked goods. I suggest you buy the best vanilla extract you can reasonably afford. It's worth it.
Banana Extract: You should be able to find this at most large grocery stores. Craft stores like Michael's or Joann also have it in the baking section.
Almond Flour: A superfine milled flour works best for baking. See my notes below about how to use almond flour.
Coconut Flour: A small amount of coconut flour helps to create the best texture.
Sweetener: You can use your favorite granulated sweetener in this sugar-free recipe. I like to use Swerve or Lakanto.
Cinnamon: This spice is perfect. It adds warmth and makes it smell amazing.
Baking Soda and Salt: added to the flour, these two round out the dry ingredients in the recipe.
Chopped Walnuts: I enjoy walnuts in banana bread! I add them to the batter and then I add more to the top of the loaf. Walnuts are a healthy source of fat and nutrients.

STEP BY STEP INSTRUCTIONS
- In a large bowl, add the eggs, mashed banana, melted and cooled butter, banana extract and vanilla extract.
- In a separate medium bowl, add the almond flour, coconut flour, sweetener, cinnamon, baking soda, and salt. Stir until combined.
- Add the dry ingredients to the wet ingredients, and stir until well combined, but don't overmix. Then stir in the chopped nuts.
- Transfer the batter to a prepared loaf pan, and if desired, top with additional nuts. Cover the pan with aluminum foil and bake as directed in the recipe card below. Halfway through the baking time, remove the foil and continue baking until the center of the loaf is cooked through.

TIPS FOR WORKING WITH ALMOND FLOUR
Baking with almond flour is different than baking with wheat flour in a lot of ways, but at the same time, it can give you results that are most similar to traditional flour if used correctly.
If you aren't an almond flour baking professional yet, you will be after making this recipe and using these tips:
- If you store your almond flour in the fridge or freezer, allow it to come to room temperature before mixing your batter. Cold almond flour will not absorb the wet ingredients the way we want it to here.
- I always suggest using a finely ground almond flour for baking. You'll get much lighter and fluffier baked goods this way.
- When measuring almond flour, use a spoon to fill your measuring cup rather than scooping down into the container. This will ensure that you are getting a proper measurement and not compressing the almond flour too much.

SUBSTITUTIONS
Keto and low-carb baking recipes can be temperamental if you try to change them too much. For that reason, I suggest following this keto banana bread recipe as written, aside from these potential swaps:
Sweetener: I know that everyone has their own preferences when it comes to low-carb sweeteners. You can use any type of granulated sweetener that is an approximate 1:1 swap for granulated sugar. Good options are Lakanto Monkfruit Sweetener, Erythritol granules, or Swerve.
Nuts: I like walnuts in banana bread, but you can add any type of chopped low carb nuts (brazil, macadamia, hazelnuts, peanuts) that you enjoy. Pecans work well. You can also leave out the nuts if you prefer.
Other Add-Ins: Instead of nuts, or in combination with them, include some sugar free chocolate chips or unsweetened coconut flakes. I enjoy Lily's chocolate chips, or a no sugar added dark chocolate bar, cut into chunks.
Flavorings: The combination of vanilla and banana extracts plus a bit of cinnamon gives this bread the perfect banana bread flavor, but you can adjust them if needed.
The rest of the ingredients, including the almond and coconut flours, baking soda, and eggs should be left as-is.
STORAGE INSTRUCTIONS
You can wrap leftovers with plastic wrap or store in an airtight container. The bread will last for 2-3 days on the counter, and maybe a bit longer if stored in the fridge.
Freeze banana bread loaves for up to 3 months. You can also store slices of this bread, individually wrapped, in the freezer for the same amount of time.
FAQS
HOW DO YOU KNOW WHEN BANANA BREAD IS DONE?
Keto banana bread, much like any quick bread or cake recipe, is done when you can stick a toothpick into the center of it and pull it out clean.
Keep in mind that oven temperatures can vary, so you may need a few minutes less or more than suggested in the recipe. I suggest checking on your banana bread about 5 minutes early just in case it's ready.
WHY ARE WE BAKING BANANA BREAD COVERED?
When testing this recipe, I found that if I baked it uncovered, the top became overcooked before the center of the loaf was set. Covering for the first half of the bake time helps it to cook evenly.
IS BANANA BREAD KETO?
Typically, the answer to this question will be no. Banana bread in its typical form is made with sugar, flour, and bananas, all of which are high in carbs.
This keto version of a classic banana bread recipe removes the sugar and wheat flour and reduces the amount of banana so that it is keto approved!

We just love this banana bread recipe. My husband has lymphedema and had to cut out carbs and dairy. I substituted olive oil for the butter. He has lost weight and his leg is much less swollen.
