The beauty of this recipe is that it relies on banana extract to give you that classic banana bread taste while keeping the carb count incredibly low.
You’ll also use one real banana to add authentic moisture and texture, but since it’s divided among 12 generous slices, each serving stays perfectly keto-friendly.
This bread is everything you want from a classic banana loaf. The almond flour and coconut flour blend creates a tender, moist crumb that’s remarkably similar to traditional banana bread.
The hint of cinnamon adds warmth, while the banana extract amplifies the banana flavor throughout every bite.

Recommended Products for This Recipe
Based on years of making keto baked goods, I’ve found that certain products really do make a difference in the final result. Here are my top recommendations for this recipe.
1. Wholesome Yum Blanched Almond Flour
Not all almond flours are created equal, and I learned this the hard way after making gritty, dense loaves with coarse brands.
This superfine blanched almond flour creates an incredibly smooth, tender crumb that mimics traditional wheat flour beautifully. It’s worth every penny for the texture alone.
2. OliveNation Banana Extract
This is the secret ingredient that makes this bread taste like authentic banana bread without loading up on high-carb bananas.
The flavor is rich and natural, not artificial or overpowering. A little goes a long way, and one bottle will last you through dozens of batches.
3. Lakanto Monk Fruit Sweetener
This monk fruit and erythritol blend is my go-to keto sweetener because it measures cup-for-cup like sugar with zero aftertaste.
It dissolves beautifully into the batter and gives the bread a subtle sweetness without any cooling effect or grittiness. Plus, it browns nicely in the oven for that perfect golden crust.
4. USA Pan Loaf Pan
If you’re serious about baking, invest in a quality loaf pan.
This aluminized steel pan distributes heat evenly, so you get perfectly browned edges without burning, and the nonstick coating means your bread releases effortlessly every single time. It’s built to last decades.
This pairs beautifully with my Chai Spiced Banana Bread for a warming fall treat.
Step-by-Step Instructions: How to Make Keto Banana Bread
Follow these detailed steps to create the perfect loaf of keto banana bread.
I’ve included all the tips and tricks I’ve learned to ensure your bread turns out beautifully every time.
1. Prepare Your Pan and Preheat the Oven
- Preheat your oven to 350°F (175°C)
- Line your 9×5-inch loaf pan with parchment paper, leaving some overhang on the sides for easy removal
- Lightly grease the parchment with butter or cooking spray
- Set the prepared pan aside while you make the batter
2. Mash the Banana
- Peel one medium overripe banana (the browner the better for sweetness)
- Place it in a small bowl and mash thoroughly with a fork until mostly smooth
- You should have about 1/2 cup of mashed banana
- A few small lumps are fine, but break up any large chunks
3. Mix the Dry Ingredients
- In a large mixing bowl, combine the almond flour, coconut flour, baking powder, cinnamon, xanthan gum, and sea salt
- Whisk together thoroughly to break up any lumps, especially in the almond flour
- Make sure all the ingredients are evenly distributed
- Set this bowl aside while you work on the wet ingredients
4. Cream the Butter and Sweetener
- In another large bowl, add the softened butter and keto-friendly sweetener
- Using an electric mixer on medium speed, beat them together for 2-3 minutes until light and fluffy
- The mixture should look pale and creamy, almost like frosting
- Scrape down the sides of the bowl as needed to ensure even mixing
5. Add the Eggs
- Add the eggs one at a time to the butter mixture, beating well after each addition
- Make sure each egg is fully incorporated before adding the next one
- This helps create a smooth, emulsified batter
- The mixture should look creamy and slightly increased in volume
6. Incorporate the Banana and Extracts
- Add the mashed banana, banana extract, vanilla extract, and almond milk to the wet ingredients
- Beat on medium speed until everything is well combined and smooth
- The batter will look slightly thinner at this point, which is normal
- Make sure there are no streaks of banana remaining
7. Combine Wet and Dry Ingredients
- Pour the wet ingredients into the bowl with the dry ingredients
- Using a rubber spatula, gently fold everything together using a sweeping motion from the bottom of the bowl
- Mix just until you no longer see any dry flour pockets
- Be careful not to overmix, as this can make the bread dense and tough
8. Add Optional Mix-Ins
- If using chopped nuts or sugar-free chocolate chips, gently fold them into the batter now
- Distribute them evenly throughout the mixture
- Reserve a small handful to sprinkle on top if desired
- The batter should be thick but still pourable
9. Transfer to Pan and Smooth the Top
- Pour the batter into your prepared loaf pan
- Use your spatula to spread it evenly into the corners
- Smooth the top gently to create an even surface
- If desired, sprinkle reserved nuts or chocolate chips on top for presentation
10. Bake to Perfection
- Place the pan in the center of your preheated oven
- Bake for 45-55 minutes, checking at the 45-minute mark
- The bread is done when the top is golden brown and a toothpick inserted in the center comes out with just a few moist crumbs
- If the top starts browning too quickly, tent loosely with aluminum foil for the last 10-15 minutes of baking
11. Cool and Remove from Pan
- Remove the pan from the oven and place it on a cooling rack
- Let the bread cool in the pan for 15-20 minutes
- Use the parchment paper overhang to lift the bread out of the pan
- Transfer to the cooling rack and let cool completely before slicing (about 1 hour)
- Cooling completely ensures clean slices and the best texture

Tips for The Best Keto Banana Bread
These tried-and-true tips will help you achieve bakery-quality results every single time you make this recipe.
Use Room Temperature Ingredients
Take your eggs and butter out of the fridge 30-60 minutes before baking. Room temperature ingredients blend together more smoothly and create a better texture in the final bread.
If you forget, you can quickly bring eggs to room temperature by placing them in a bowl of warm water for 5-10 minutes.
- Measure your almond flour correctly by spooning it into the measuring cup and leveling off, never packing it down
- Choose superfine blanched almond flour for the smoothest texture
- Make sure your baking powder is fresh (test it by adding a pinch to hot water; it should fizz vigorously)
- Don’t skip the xanthan gum as it helps bind everything together and prevents crumbling
- Use the ripest banana you have for the best natural sweetness and easiest mashing
- Let the bread cool completely before slicing to prevent it from falling apart
- Store leftovers in an airtight container to keep the bread moist
- For a stronger banana flavor, increase the banana extract to 3 teaspoons
- If using allulose as your sweetener, watch the bread closely as it tends to brown faster than other sweeteners
- Test doneness with a toothpick in multiple spots since ovens vary

Health Benefits of Key Ingredients
Let me share why the ingredients in this keto banana bread aren’t just delicious but also nutritious for your body.
Almond Flour
This is a true nutritional powerhouse that makes keto baking possible. Unlike wheat flour, almond flour is naturally low in carbs while being incredibly high in protein, healthy fats, and vitamin E.
- Rich in vitamin E, a powerful antioxidant that supports skin health
- High in healthy monounsaturated fats that support heart health
- Contains magnesium, which helps regulate blood sugar levels
- Provides fiber for digestive health
- Naturally gluten-free and grain-free
- Contains protein to help keep you full and satisfied
- Low glycemic index means it won’t spike blood sugar
- Rich in manganese, important for bone health and metabolism
Coconut Flour
Just a small amount of this flour adds significant fiber and helps create the perfect texture. It’s one of the most nutrient-dense flours available and adds barely any carbs.
Banana Extract
All the flavor of banana without the sugar and carbs. It’s derived from real bananas but concentrated, so you get maximum taste with minimal impact on your blood sugar.
Eggs
Each egg provides complete protein and essential nutrients like choline for brain health. They also help bind the bread together and create that tender, moist texture we all love.

FAQs About Keto Banana Bread
1. Can I make this without banana extract?
Yes, you can make this recipe without banana extract, but the banana flavor won’t be as pronounced.
If you skip it, I recommend using two bananas instead of one to boost the flavor. Keep in mind this will increase the net carbs per slice to about 5-6 grams instead of 3.
2. Why is my keto banana bread dense or gummy?
This usually happens from using too much coconut flour or not measuring the almond flour correctly.
Coconut flour is extremely absorbent, so even a little extra can make the bread dense.
Always spoon your flours into measuring cups and level them off without packing down.
3. Can I make muffins instead of a loaf?
Absolutely! This batter works perfectly for muffins. Divide it among 12 muffin cups lined with paper liners, filling each about 3/4 full.
Bake at 350°F for 22-28 minutes until a toothpick comes out clean.
4. What’s the best keto sweetener for this recipe?
I prefer monk fruit sweetener or erythritol blends like Lakanto because they dissolve well and have no aftertaste.
Allulose works beautifully too but will make the bread brown faster, so watch it carefully. Avoid stevia-only blends as they can leave a bitter taste.
5. Why do I need xanthan gum?
Xanthan gum acts as a binder in gluten-free and keto baking, helping hold everything together so your bread doesn’t crumble.
Without the gluten from wheat flour, we need this ingredient to create structure.
If you don’t have it, you can try 1 tablespoon of ground flaxseed, but the texture may be slightly different.
