Keto Peanut Butter Cookies!
I’m surprised it took this long to post low carb peanut butter cookies, I guess because they’re gone so quickly once they’ve baked!
Peanut butter cookies hold a special place in my heart because they’re the first dessert recipe I ever made at the young age of 10. And it figures, there are only three ingredients needed for them! Traditionally, they are sugar, peanut butter and an egg. Simple enough for kids and delicious enough to enjoy at any age.
Luckily, it is easy to create a low carb version of peanut butter cookies and still keep the recipe extremely simple. To make these low carb and keto-friendly, the only thing needed is to swap out sugar for erythritol! Even my 10-year-old baking self could still make them!

The brand of erythritol we use is Swerve or Sukrin. They’re found in a lot of grocery stores near us and fit our budget when we need to stock up on low carb sweeteners! Swerves erythritol is ground much finer than most erythritols which makes baking a lot simpler because erythritol is a bit more difficult to dissolve in water than regular table sugar. The finer grind of the sweetener makes it blend into the keto peanut butter cookie batter well. You can also get a confectioners’ version of erythritol which helps in baking even more- especially for frosting!
After you make the cookie dough for these keto peanut butter cookies, you can scoop the dough into balls and then roll them in some extra granulated erythritol. This will add a little sweetness and it is also a classic touch that is added to many peanut butter cookies. That sparkly sweetener on the outside is hard to resist!
You’ll love these cookie recipes, too:
The original recipe that’s been posted countless times all over the internet calls for a cup of sugar for about 12-15 cookies. Based on my experience, I decided to add in half a cup of erythritol. Being keto-adapted, my tolerance for sweets has decreased drastically. And experimenting with keto desserts has taught me to cut the sweetness! Even though erythritol is only about 70% as sweet as sugar, I still used a small amount and the low carb peanut butter cookies still turned out sweet and perfect! You won’t even notice that the sugar content has been reduced!
I suggest starting off with this small amount of sweetener and doing a taste-test. I figured since peanut butter is a treat to me to begin with, adding a whole ton of sweetener wouldn’t really be necessary. Let that natural sweetness of the peanut butter shine through!
Here are our keto-fied low carb peanut butter cookies!
| Servings: cookies |
- 1 cup peanut butter (no sugar added)
- 1/2 cup So Nourished erythritol sweetener
- 1 large egg
- Preheat your oven to 350°F and gather your ingredients! Place half a cup of granular erythritol into a Nutribullet and blend for a few seconds. You should end up with a fine, powdered sweetener!
- Combine the peanut butter, powdered erythritol and the egg and mix very well.
- Roll the cookie dough into 1-inch balls and place on a parchment paper lined baking sheet. Press down with a fork twice to create the iconic peanut butter cookie pattern.
- Bake in the oven for about 10-15 minutes or until you see the cookie edges turn a darker brown.
- Let them cool on a wire rack and enjoy with a yummy glass of nut milk!

Oh! I just mixed the peanut butter and erythritol but just realized I forgot to powder the sweetener! Is there a fix?
Unfortunately not! Your cookies will still be delicious but may be just a bit grittier.
Hi! So I’m a little confused. Using the PB and the erythritol you have linked, these would be 8 net carbs each for 15 cookies. That is excluding the fiber. What am I missing. Does some of it cook off or something?
We also exclude sugar alcohols since they have as fiber does in the body. Erythritol is effectively 0 net carbs 🙂
If I am using Monkfruit sweetener, what’s the conversion? Also, can these be made with a few Lily’s chocolate chips thrown in?
Are you using a monk fruit-erythritol blend or pure monk fruit?
erythitol blend
You can use the same amount of your monk fruit-erythritol blend. Perhaps just a bit less since it’s made to be sweeter than erythritol alone.
Umm so all I have is skippy peanut butter. Is that a definite no? Should I go to the grocery store or will I be ok.
It depends how strictly you’re following keto! We recommend a no sugar added peanut butter – it’s better in so many ways.
Love this recipe! I used sunbutter instead because I follow a keto that doesn’t eat peanuts. Added a 1/2 tsp salt because my sunbutter is unsalted, and 1/4 tsp of vanilla. Amaaaazing!
Mine seemed a little iffy to roll as the recipe called for, so I refrigerated the dough for 30 mins beforehand, Worked much better!
these are my favorite cookies…super easy to make and so yummy! I’ve even tried them with Almond Butter instead of Peanut Butter and they’re just as good
Good to know!
I am surprised of the use of the peanut butter because it contains sugar! I am new but thought sugar was taboo!
Many peanut butter brands do not add sugar to their product!
I used stevia instead — it was good but very sweet tasting. I think the recipe – or at least my adaptions — would benefit from a little salt.
Hi, it’s really lovely recipe. Can I just use peanut butter and egg only? Will it work? I really don’t like sweet thing, not even any kind of sweetener…
Yes, you can use 1 tbsp of egg white protein if you leave out the sweetener.
Hi. If I use Stevie with erythritol would I use 1/4 cup? It’s granular not powder and the conversion is half of granular sugar. Thanks.
Yes, that sounds about right.
Hi! Is the erythritol 1/2 before it’s ground? How much does it measure after? I have a powdered version and I’m wondering how much of that I would use.
Thanks!
I meant 1/2 CUP !
You would need roughly double the powdered erythritol 🙂
So 1 full cup if you are using Confectioners Swerve? Just want to be sure! I’m going to make these tonight! 🙂
That’s right!
Getting ready to make these BUT I use Spend on everything…IF I make it as fine as possible would that work? THANK YOU!
If that’s what you prefer, then sure. But I would not recommend Splenda, it’s artificial and not keto friendly.
Hi, I’ve made some of these tonight, they were really lovely and so simple! Such a great recipe, thanks for sharing !
Just made these with almond butter and recipe is a keeper!
Thanks for the feedback! Some people love the almond butter versions, some hate them. I guess it all depends on the nut butter 🙂
I picked up a jar of almond butter. That should work too, no?
Definitely, give them a try!
It’s a no on almond butter….They taste horrible (or at least to me and my fiance).
Oh no! Well, thanks for letting us know 😀
can I use granulated swerve instead of powdered??
You definitely can, but you’ll need only half as much granular.
