Before you freak out, very little banana has been used. Sugars are still low in each slice. However, we have included a couple of substitutes to make delicious low carb bread without the banana if you prefer.

Banana – using a ripe banana in the bread makes for a moist keto banana bread. I use only 100g of fresh banana over the whole loaf. So the carbs are reduced significantly when cut into 16 thick slices. Banana can be replaced with extracts, flavoured collagen powders, or swapped for avocado or cream cheese if preferred.

Butter – I just use salted butter. You can use unsalted butter or a neutral-tasting olive oil (not extra-virgin) to make dairy free banana bread. Oils like fractionated coconut oil or MCT oil would be perfect.

Almond Meal – blanched almond flour, or sesame flour can be used in this recipe. I have only tested this keto banana bread with almond flour. To do it without or with just coconut flour, I am sure that would be possible with a 1:4 ratio of coconut flour to almond meal.

Coconut Flour – the coconut flour can be omitted if preferred and add an extra half cup of almond meal in its place. I prefer to add coconut flour to help take up the liquid and give a nice texture to the banana bread.

Sugar-free Maple Syrup – I use Sukrin Maple Syrup it is thicker than all the other brands I have tried. However, you can use any brand you prefer or flavour with vanilla extract instead.

Yoghurt – I use our 2-Ingredient Yoghurt in the banana bread recipe. You can however use unflavored Greek yoghurt. Coconut cream and coconut yoghurt are great for a dairy free option.

Sweetener – I use Sukrin Gold sweetener for a delicious caramel flavour. You can use any sweetener of choice like erythritol or monk fruit sweetener. Just be mindful of the level of sweetness of the sweetener you use.

Banana Bread Variations and Optional Extras

Once you have perfected your basic low carb banana bread recipe you can start to change it up for something different. Here are just a few of my favourite ideas.

Keto Banana Nut Bread – add 1/2 to 1 cup of your favourite nuts. I love the brazil nuts in mine, but walnuts, pecans, hazelnuts or macadamias are all great choices too.

Keto Chocolate Banana Bread – whether you make it with chunky sugar free chocolate or sugar free chocolate chips both are great decisions. For a fun idea add a little cacao to half the mixture and make marbled banana bread. (That sounds too good to me so now I will have to make it).

No-Banana Banana Bread – a little banana extract can go a long way. Alternatively, you can also add Vitalzing Banana Milk Drops (adjust the amount of flavour to suit you) or use Banana Flavoured Collagen and Protein Powders.

This recipe can have no banana added at all. Swap fruit or vegetables like pumpkin, mashed and cooked choko, or 100g of avocado in place of the banana. Add any spices or extracts to flavour it.

How to Make It

Instructions have been added to the recipe card to make banana bread in a Thermomix or Magimix appliance. We try to ensure all our easy keto recipes have thermal cooking options.

Step 1. Preheat the oven to 170℃/335°F. Line a 23cm x 11cm (4 x 9 inches) loaf pan with baking paper. Place all the ingredients into a large mixing bowl (reserve some of the nuts to add to the top). Mix until combined.

Step 2. Spoon into a loaf pan. Bake in the preheated oven for 50-60 minutes.

Step 3. The loaf is ready when a skewer comes out clean. Leave the banana bread cool in the pan for 10 minutes before turning it out onto a wire rack. Allow to cool completely before slicing.

HOT TIP – I prefer to refrigerate overnight before slicing. The flavours develop and the loaf is perfect for slicing after chilling.

Notes

The recipe nutritional has been calculated using 100g of bananas and no nuts. The net carbs will significantly be reduced if using the banana extract in place of bananas.
This consistency of the raw loaf is more of a sticky batter than dough.
I seriously recommend Bob’s Red Mill Double Acting Baking Powder as it helps leaven the bread beautifully.
Net carbs can also be reduced should you choose to slice thinner. Even in this sized pan you can easily cut 22 decently thick slices.
For a vegan/vegetarian version butter could be exchanged for Nuttelex or light tasting olive oil, and the yoghurt for coconut yoghurt or coconut cream.
For egg free – use 12 tablespoons of aquafaba whipped until fluffy and fold through all ingredients.
For a nut-free version, I am yet to test this but the almond meal could be replaced with a combination of pepita and sunflower seed meal.
This recipe yields approximately 16-18 servings. The actual number of servings will depend on your preferred portion sizes. 
To calculate the weight of one serving, prepare the recipe as instructed. Weigh the finished recipe, then divide the weight of the finished recipe by 16-18. The result will be the weight of one serving. 
Nutritional values shown are guidelines only. They are for 1 serving using the ingredients listed. 
All recipes have been tested using all of the cooking methods included by various recipe testers.
When making the banana bread in the air fryer for the first time just keep a close check on the temperature and timing. Models do vary slightly and the time or temperature may need to be adjusted to bake the perfect loaf.
Store in an airtight container in the fridge for up to 5 days. Alternatively, store in an airtight container and freeze.
The recipe card instructions contain the most basic of steps and a list of ingredients. If you have any queries, questions or are unsure of substitutions, please scroll up to the blog post for more information.
