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.
When you google 'healthy banana cookies', you'll find recipes containing ingredients such as oats, dates, maple syrup and spelt flour.
Of course, in the scheme of things 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 erythritol for additional sweetness.
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. 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) erythritol as well.
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.
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.
The recipe works without baking powder. However, your cookies will have a denser texture.
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!
FAQ
It depends on the amount. Banana has a high sugar and carb content. According to Food Data Central, 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.
Absolutely. Replace the butter in the recipe with coconut oil or more almond butter.
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.
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.
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.

Can I make this without the substitute sugar ?
Katrin Nürnberger
Yes, of course. Perhaps add more banana then so they are sweet enough.
Celia
Thanks so much.
Wieke
Delicious. Mine needed approx. 17 minutes in the oven, I added a pinch of salt and left out the sweetener. They are perfectly sweet without it for my taste! Thank you for this great recipe.
Dave
I made these today, so easy and very tasty. I sub'd peanut butter for almond butter. Thanks for the recipe
Amber
I am makin them currently and I made them accidentally way too big. But mine aren’t hard like yours. More poofy and soft. What did I do wrong?
Katrin Nürnberger
These cookies are not supposed to be crispy. Mine were nice and soft on the inside. However, I do recommend making them with an erythritol based sweetener. Any other sweeteners, especially allulose, will result in even softer cookies.
Laura
These cookies are really soft and cakey, kind of like muffin tops but flatter. I used peanut butter and they were delicious. The recipe made 12 cookies for me.
Sophia
Incredible!!! Thank you new to keto and with your delicious recipes I reckon it’s all been made a lot easier, especially with these to snack on only downside was I made them too big, so they won’t last long! I think my tablespoons are waaaay to generous
Amanda Nagy
can you substitute the 50g golden erythritol with monk fruit sweetner ?
Katrin Nürnberger
Yes. Most monk fruit sweeteners are actually blended with erythritol or another sweetener as pure monk fruit is extremely sweet on its own. As long as your monk fruit sweetener is a 1:1 sugar substitute, you can use it without issues.
