Put these sugar free peanut butter cookies on your to-make list! They are soft and chewy and super satisfying. Even better, this easy coconut flour peanut butter recipe requires just 6 ingredients and you stir it together with a fork. Only 2.3g net carbs per cookie!
I have officially come full circle on my love affair with gluten free low carb peanut butter cookies. I've covered ALL THE BASES, guys! There are now 3 different ways to make PB cookies on this very website:
- Keto peanut butter cookies. The classic! This is the one for purists. 4 ingredients, no nut flours.
- Almond flour peanut butter cookies. Includes almond flour as a twist on the original. More fluffy and lighter in taste.
- And now - the coconut flour version! For everyone who can't have or doesn't like almond flour. Let's see them all next to each other:
The Classic 
The Almond Twist 
The Coconut Joy
I honestly love all three recipes. In my opinion, it's all about variety! You could argue that I am slightly obsessed with cookies, and I'd have to whole-heartedly agree.
In fact, did you know I have written an entire cookbook about Keto cookies? The original keto peanut butter cookies recipe made it into the book because it's THAT good. But there are tons more exclusive cookie recipes in the ebook that you won't find anywhere else.
I got sidetracked. Time to talk coconut flour peanut butter cookies!
Sugar free peanut butter cookies ingredients
Coconut flour: AKA the diva of low carb flours. It absorbs lots of liquid and the end result can be brittle if you don't get the ingredient balance right. However, if used correctly coconut flour recipes taste delicious. Plus, it's a super-healthy low carb flour - high in fibre and low in carbs. Read more about the benefits of coconut flour here.
Peanut butter: Choose a natural peanut butter that contains ideally just one ingredient - peanuts. Plus maybe a little salt. Here in the UK, I like the Meridian brand or my latest discovery, Manilife. They have a deep roast flavour that's just irresistible.
Eggs: There's 2 eggs in this coconut flour version, instead of just one egg like in the other two recipes. Egg helps to bind the coconut flour dough.
Powdered sweetener: I used an erythritol monk fruit sweetener that 's a 1:1 sugar replacement. Allulose or xylitol are also options - they would make these sugar free peanut butter cookies even softer.
Baking powder, vanilla extract and salt: For a lighter, fluffier, tastier cookie.
How to make coconut flour peanut butter cookies
Put all ingredients in a bowl and stir together with a fork until a dough forms. Use your hands to roll into a ball. The dough will be slightly sticky. If it sticks to your fingers, simply wet them with a little water.
Cut into 9 and roll into balls. Wet your hands again if needed. Place on a baking tray lined with parchment paper.
Flatten each peanut butter coconut flour dough ball into 1 cm thick / 5 cm diameter disks using a fork, making a criss cross pattern. Clean the fork in between indentations.
Bake for 8 - 10 minutes (I baked for 9). Remove from the oven and let cool completely before enjoying as they firm up as they cool.
Soft vs. crispy
For soft, chewy cookies, make them thick like I did and bake 8-10 minutes.
For crunchy cookies, flatten them more and keep them in the oven for 12 minutes or until the tops are golden brown.
Recipe Variations
These low carb keto peanut butter cookies have a gentle coconut flavour which I think is delicious. But for all of you who love the idea of coconut flour but not the taste, simply add 1 tsp almond extract.
You could also add sugar free chocolate chips to the batter to make low carb peanut butter chocolate chip cookies or sprinkle sea salt on top before baking.
It should also be possible to use crunchy peanut butter for a more rustic result. Or replace the peanut butter with almond butter or any other nut or seed butter!
