These sugar-free banana cookies are moist, soft and fluffy! Imagine banana bread turned into a cookie and you get the idea. My keto banana cookies use real banana, yet they are only 1.6g net carbs per cookie.

Do you like banana bread? Then you will love these cookies. Because they are bite-sized banana bread treats!
Regular readers of this blog will know my keto banana bread. I tweaked it a little and came up with these cookies. Seriously, I cannot wait for you to try them out.
Ingredients
Below are the ingredients you'll need:

- Almond flour or ground almonds
- Banana - needs to be over ripe so it's sweeter
- Egg
- Butter - softened
- Almond butter
- Walnuts - optional
- Baking powder
- Cinnamon
- Sweetener
I used ¼ cup (50g) of golden erythritol monk fruit blend. It tastes a bit like brown sugar and I find it works well in any recipe that requires cinnamon. However, you can use regular (white) sweetener as well, whether that's allulose, xylitol or Bocha Sweet.
Instructions
This section contains step-by-step instructions and photos that show how to make this recipe. See the recipe card for full information on ingredients and quantities

1.) Mash the banana with a fork. Then blend all ingredients (except for the walnuts) in a bowl with an electric mixer until smooth.

2.) Dollop the cookie dough onto the cookie sheet lined with parchment paper. Space them out on the baking sheet because the batter spreads. Top with the crushed walnuts.

3.) Bake until lightly browned. Remove from the oven and let cool completely before handling. The cookies are very soft when straight out of the oven. They firm up as they cool.
Katrin's Tips
A pinch of salt works well in this recipe. Or consider adding ¼ spoon of ginger and / or nutmeg.
Instead of walnuts, you could add pecans or hazelnuts or even sugar free chocolate chips!
Recipe Variations
You can replace the almond butter with peanut butter. Make sure it's nice and runny and not hard and crusty! As peanut butter tends to be firmer than almond butter, start with ¼ cup / 25g almond flour.
Dairy free cookies: Replace the butter in the recipe with coconut oil or more almond butter.
Vegan banana cookies: In addition to using coconut oil, use a flax egg in place of the egg. It may also help to add ¼ teaspoon xanthan gum or 1 teaspoon psyllium husk powder as a binder.
The recipe works without baking powder. However, your cookies will have a denser texture.

Recipe FAQs
It depends on the amount. Banana has a high sugar and carb content. 100g of banana contains 23g of total carbs. We're only using 80 grams or ⅓ cup of mashed banana in the entire recipe, about 1 small banana. This way we're getting all the banana taste without having to resort to extracts. And one cookie only contains 1.6g net carbs.
Cool the cookie dough in the fridge for 20 minutes so the butter can solidify. Also, stir the almond butter before using. If your batter is soft because of the almond butter, add an additional tablespoon of almond flour. Though, cooling in the fridge will also help.
Yes! My banana cookies are healthy, because they are low in carbs. When you google 'healthy banana cookies', you'll find recipes containing ingredients such as oats, dates, maple syrup and spelt flour. These ARE better options than white flour and sugar. But they will still raise your blood sugar levels.
I'm keeping this recipe low carb (and gluten-free!) by using almond flour and almond butter instead of flour. And I'm using a sugar free sweetener.
Storage
Store sugar free banana cookies in a cookie jar or in an airtight container. They are fine on the kitchen counter for a couple of days. Or, store in the fridge for 5-6 days.
You can also freeze them for up to 3 months.

Hi
I made this cookies and they were delicious. My cookies came out super soft, almost cake like even when they cooked down. Can you tell me what I can add or adjust to make them firmer please, and not falling apart.
Katrin Nürnberger
To make them firmer, you'd need to add more almond flour or perhaps coconut flour or ground flaxseed.
