Keto banana bread (no actual bananas) is a low-carb, grain-free version of the classic quick bread that allows you to enjoy the comforting flavours of banana bread while following a ketogenic diet.
It typically uses a combination of low-carb flours like almond and coconut flour, along with eggs, butter or coconut oil, and low-carb sweeteners.
To mimic the banana flavour without using real bananas, which are high in carbs, keto banana bread recipes often incorporate banana extract or a small amount of mashed ripe bananas balanced with the other low-carb ingredients.
The result is a moist, dense loaf with the familiar aroma and taste of banana bread, but with significantly fewer carbs and no sugar.
Ingredients
- 250g (2 1/2 cups) almond flour
- 112g (1 cup) coconut flour
- 2 tsp baking powder
- 1 tsp cinnamon
- 1/2 tsp salt
- 230g (1 cup) butter, softened
- 150g (3/4 cup) granulated sugar substitute (monk fruit, erythritol)
- 4 large eggs
- 1-2 tbsp banana extract
- 90g / 6 tbsp Greek yogurt or sour cream
- 60g (1/2 cup) chopped walnuts or sugar-free chocolate chips (optional)
Method
- Preheat oven to 175°C (350°F). Grease a 9×5 inch loaf pan and line with parchment paper.
- In a large bowl, whisk together the almond flour, coconut flour, baking powder, cinnamon and salt.
- In another bowl, beat the butter and sugar substitute until fluffy. Beat in the eggs one at a time, then stir in the banana extract and Greek yogurt.
- Add the dry ingredients to the wet ingredients and mix until fully combined. Fold in the walnuts or chocolate chips if using.
- Pour the batter into the prepared loaf pan and smooth the top.
- Bake for 50-60 minutes, tenting with foil halfway through to prevent over-browning. The bread is done when a toothpick inserted in the center comes out clean.
- Allow the bread to cool completely before slicing.
Notes
This keto banana bread uses almond flour, coconut flour and banana extract to mimic the flavor and texture of traditional banana bread, without any actual bananas.
The Greek yogurt helps keep it moist.
Feel free to add nuts or sugar-free chocolate chips for extra flavour and texture.

Storage
Refrigerator Storage:
- Most keto banana bread recipes recommend storing the bread in the refrigerator, completely covered, rather than at room temperature
- When refrigerated, keto banana bread will keep well for up to 2 weeks
Freezer Storage:
- Leftover slices or entire loaves of keto banana bread can be frozen for longer storage
- When frozen, the bread will keep for up to 3 months or up to 6 months
- It’s best to wrap the bread tightly in plastic wrap or place in ziplock bags before freezing
Room Temperature:
- Unlike traditional banana bread, keto versions are not recommended to be stored at room temperature for more than a few hours, as they can dry out or spoil more quickly without preservatives
In summary, while regular banana bread can last several days at room temp, most sources suggest keto banana bread has a relatively short room temperature shelf life.
Refrigerating for up to 2 weeks or freezing for 3-6 months are the recommended storage methods to maximize freshness and shelf life.
Keto Banana Bread gone off?
Checking here are some signs that keto banana bread may have gone bad:
- Mold Growth
Like any bread product, if you see any mold growth on the surface or inside the keto banana bread, it has spoiled and should be discarded immediately. - Off Smell
If the keto banana bread develops an off, sour, or rancid smell, it is likely starting to go bad and should not be consumed. - Dry or Hardened Texture
Since keto banana bread lacks preservatives, it can dry out and harden much faster than regular banana bread when left at room temperature. Excessive dryness or a stale texture is a sign it has gone stale. - Discoloration
If the bread develops dark spots, green tinges, or other discolorations that weren’t there initially, this can indicate spoilage. - Slimy or Sticky Texture
A slimy, gooey, or overly sticky and dense texture that seems “off” is not a good sign for keto breads and likely means it has spoiled.
If stored properly and none of the above signs of spoilage are present, most keto banana bread recipes should remain safe to consume for the recommended refrigerator or freezer storage times.
