3 Ingredient Keto Sugar Free Flourless Cookies (Paleo, Vegan, Low Carb)
The old fashioned 3 Ingredient flourless peanut butter cookies get a sugar free, egg free and healthy makeover! These three-ingredient sugar-free flourless cookies are completely keto, paleo, vegan, gluten free, grain free and dairy free!
Sugar Free Flourless Keto Peanut Butter Cookies
You asked I delivered.
When I first shared these peanut butter crunch bars, many of you mentioned how they reminded you of homemade childhood treats. This was once again lamented when these 3-ingredient corn flake crunch bars were shared. Back in 2014, I shared the classic 3 Ingredient grain free peanut butter cookie recipe– Sugar, peanut butter, and an egg.
Now? We’re giving it a sugar free, keto, Paleo AND Allergen-friendly makeover, along with a tested vegan option using no eggs.
Readers on Facebook had mentioned that they’ve often interchanged the sugar for Splenda or aspartame, two sugar substitutes I don’t usually use. Personally, when I test recipes to be completely sugar free or needing a granulated sweetener, I almost always use monk fruit sweetener.
For those who don’t know what monk fruit sweetener is, it’s a natural, stevia blend. It looks and feels like sugar, and the best part? It does NOT leave you with a bitter aftertaste, something which many stevia blends possess. They also bake VERY well.
Keto Peanut Butter Cookies Recipe
Texture wise, these cookies are super deceptive. Bake them too short, and they’ll be super soft and need to be enjoyed pretty much immediately or within the first day. Bake them too long, and you’ll be left with crackers instead of cookies. The happy balance is to remove the cookies from the oven when they still look soft. Once they are out of the oven and cooling, they will firm up VERY fast, but still be chewy, soft and irresistible.
The original recipe calls for one cup of sugar (or fake sugar), but I found with monk fruit sweetener, three-quarters of a cup was plenty. In fact, I found them to be a little too sweet, which is why SALTED almond butter (or peanut butter) was the next best sub.
Low Carb Peanut Butter Cookies
The traditional recipe is infamous for using peanut butter, and if that is no issue for you, keep it the same. However, if you follow a paleo or nut free lifestyle, check out these tested subs. Almond butter or smooth cashew butter are the best swaps for it, especially if you get the salted, drippy kind. To keep it nut-free, smooth sunflower seed butter or creamy soy nut butter can be used. Please note, if you use sunflower seed butter, your cookies will have an odd shade of green.
Finally, an egg is the final magically ingredient, but my vegan friends need an option too. After testing out flaxseeds, energy-G egg replacer and even a formed chia egg, I found them to either be too crumbly, too wet or just a big puddle of peanut butter and sugar. I found this recipe which mentioned using ground chia seeds (NOT formed into a gel- just blended with the cookies) and was stoked to see it work. It also provided a much better and chewier texture.
These aren’t your grandma’s classic 3 ingredient peanut butter cookies but ones which my sugar-free, paleo and vegan readers can now enjoy. Three ingredients and 20 minutes from prep to dunking in milk.
3 Ingredient Flourless Sugar Free Cookies (Keto, Low Carb, Paleo, Vegan, Gluten Free)
Ingredients
For the original version:
- 1 cup smooth almond butter can sub for any nut or seed butter of choice
- 3/4 cup granulated sweetener of choice I used a monk fruit stevia blend
- 1 large egg
For the egg-free version:
- 1 cup smooth almond butter can sub for any nut or seed butter of choice
- 3/4 cuo granulated sweetener of choice I used a monk fruit stevia blend
- 3-4 tbsp ground chia seeds *
Instructions
- Preheat the oven to 350 degrees Fahrenheit and line a baking tray with parchment paper or a cookie sheet.
- In a large mixing bowl, combine all your ingredients and mix until well combined. If you use the egg-free option, start with 3 tablespoons of ground chia seeds. If the batter is too thin, add the extra tablespoon.
- Using a cookie scoop or your hands, form small balls on the cookie sheet, spread 3-4 inches apart. Press each ball into a cookie shape and press down with a fork. Bake for 8-10 minutes, or until cookies are 'just' golden brown but still soft. Remove from the oven and allow to cool until soft, firm and chewy.

these look great! I always use the granulated monk fruit sweeter. Its my favorite
I love egg free and naturally sweetened treats.
You and me, both!
These photos are GORGEOUS! Going to have to check out the granulated monk fruit sweetener, as I have to admit I’ve never tried it!
Please do! 🙂
I have to try this! I love that it’s only 3 ingredients 🙂
Please do!
I enjoy your recipes but you have so many ads that I’ve been avoiding your posts lately. ?
Have you tried making these with liquid stevia? Can’t have xylithol or erithrol unfortunately. Thanks in advance!
I haven’t, let me know if it works for you!
Hi,
Thank you for this recipe which looks great. Have you tried making it with liquid stevia? Can’t eat xylitol or erythritol unfortunately, and the only monk fruit sweetener I can find contains a blend of monk fruit and erythritol.
Thank you in advance!
Hi I haven’t- Let me know if it works for you!
Followed recipe and even bought monk fruit sweeter..cookies are a wet mess!!
Not sure what you did wrong then, these have been made successfully by thousands of readers 🙂
What sweetener do you actually use? The link goes to a monk fruit /erithrytol blend, not a stevia/ monk fruit blend.
That is what I use, but you can use any sugar-free blend 🙂
hi! can we add protein powder in this?
Working on a version of this!
Is the 3/4 cup for zero calorie sweetener? If I used cane sugar, would it still be 3/4 cup?
Yes, it would be 🙂
Can you make the 3-ingredient PB cookies using a flax egg (ground flax seed) instead of ground chia seeds?
I haven’t tried- You could experiment and see!
you can use coconut sugar as a sugar substitute and you substitute it for equal amounts of regular sugar so if a recipe calls for a cup of granulated sugar you would just substitute it for a cup of coconut sugar taste is pretty spot-on
Can you use Xylitol for the sweetener? How much do I use for this recipe?
hi, can we use honey as substitute for the sweetener?
Hi Miki! It needs to be granulated, I haven’t tried with anything else 🙂
How many carbs are in these cookies
It’s included in the recipe card 🙂
No sugar doesn’t mean monk fruit, it means no sugar. Just like no stevia means no stevia
For me and my readers, this is the case. So yes, no sugar. enjoy.
My experience wasn’t what I’d hope for. I used PB2 powered peanut butter (reconstituted) monk fruit golden & an egg. Exceptional (sickening sweet). Also, when removed from the cookie sheet, they had a dense & rubbery texture. Suggestions?>
Glenda, I never use PB2, it just doesn’t yield the texture that only peanut butter or another nut butter provides. Your results don’t surprise me. I would make it as stated.
Hi, can we substitute the sweetener with nut flour 1:1? I’m making this as a gift to someone who doesn’t like sweet. Thank you 🙂
That won’t work at all 🙂
Thanks. Was craving these but wondering if Swerve would work for the sugar. Suggestion: list servings per batch. I sometimes use a recipe app to calculate nutrition and if I make changes or substitutions it’s easier to compare if I know how many servings you used in your calculations (without having to calculate backwards from your Calorie information).
Hi! Swerve should be fine 🙂
you mention several times that you use a monk fruit/stevia blend but all of your links are for the Lakanto monkfruit/Eurythritol sugar product. This product does not contain stevia. Can you please clear up the confusion?
Thanks! 🙂
This is the one I use- I hyperlink and mention stevia because in some countries, they have stevia baking blends, that work.
Hi there. These look yummy. I looked to see how many servings your recipe makes so I can calculate my macros. Did I miss it? Thank you!
Never mind! Found it! Lol 🤣
I tried making these according to the instructions (1 cup peanut butter, 3/4 cup coconut sugar/monk fruit sweetener , and 1 egg), but they were wet and not dough, like at all. I added an addition 1/4 cup of sugar + 1/4 of white wheat flour. Then they were perfect!
