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!
- 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 my goodness!! I just got home from getting almond butter and I’m about to try this recipe out!! I’m so excited to eat a cookie ❤️❤️❤️
You’re going to love them!
I used honey peanut butter and they were super super soft. Is it because of the peanut butter I used or are the cookies super super soft?
These cookies are on the softer side. Remember to let low carb baked goods cool completely before handling. Also, I’d use an all natural, no sugar added peanut butter, since those carbs can add up!
I’m new to keto diet. Can I just use my normal peanut butter? I thought maybe it had to much sugar… so excited about trying these!! Thanks for the recipe
How much sugar does your peanut butter have?
Hi. Just wondering if you use stevia if they would still taste just as good?
Yes, that should work!
I thought I’ve read that legumes are to be avoided when following a Keto way of life. Peanuts fall into the legume category.
Some people avoid peanuts, others don’t! It’s personal preference. We choose to eat them in moderation, but you can make this recipe using almond butter instead 🙂
Would you get the same results if you used powered peanut butter that water is used to make desired creaminess?
Nope, definitely use real peanut butter!
New to Keto based diet…..I’m excited to try these 🙂
What other sweeteners can be used?
Try xylitol or a monk fruit/erythritol blend! Or a bit of stevia extract but you will end up with smaller cookies.
Hi Vicky! I love these cookies and so does my husband. Have you ever tried making these with almond butter instead of peanut butter? If so, were they good? 😉
I’ve never personally tried, but a few people have done it with almond butter and said it worked great for them!
Hi! I’m baking for a precious boy who likes his cookies crunchy, not chewy. Do these fit the bill? They look tasty, though. Thanks!
These are not exactly crunchy, unless you toast them maybe? Consider adding some chopped peanuts to the batter, that might make them crunchier!
These were excellent…not too sweet or anything. Thank you for sharing, so glad to have a cookie!!!
These are delicious. How many total carbs do they have? I see net carbs listed but wondering about total carb count. Thank you!
Hi Arianna, we only calculate net carbs since we are not affected by sugar alcohols and fiber. Feel free to calculate the total carbs – our preferred way is by using the MyFitnessPal app!
I just realized that I used sugar-free peanut butter, the only peanut butter I have and your recipe doesn’t call for it. I hope they turn out okay! I just put them in the oven.
They should be totally fine! Perhaps a bit sweeter, but still tasty. 🙂
Thank you for this recipe! I’ve made several batches of these over the past 4 months. My husband and I love them.
this are CRAZY good. Favorite keto recipe so far. I LOVE THESE COOKIES. recommend 100%
I made these the other night and the bottoms burned……..so I went out and bought a silicone sheet and they still burned…… is it because I used Jiff PB…….????????
No I don’t think that’s why. Perhaps your oven is very strong? Try baking the cookies on the top level of your oven (or further away from the heat source).
could I use monk fruit powder sweetner for these
Yes, of course! That would be very tasty!
