These quick and easy keto peanut butter cookies are ultra soft, chewy, and absolutely impossible to resist!
I first made this keto peanut butter cookie recipe for a friend on a keto diet, but they turned out so well that I ate five cookies right out of the oven and ended up having to bake a second batch.
With just a few basic ingredients, and no flour or sugar required, they might just become your new favorite cookie recipe!

This is one of those easy keto desserts that people who aren’t on a special diet enjoy too, because who doesn’t love peanut butter cookies???!
Since the recipe is egg free, you can eat the raw cookie dough while you bake, and if you’d prefer no bake peanut butter cookies, it’s fine to skip the baking step completely.
(See photo above of the unbaked cookies.)
Peanut Butter Cookie Ingredients
The flour:
I used almond flour (or almond meal) for these, which is not actually flour at all; it’s simply ground-up almonds that have been blended into a fine texture resembling flour.
If you prefer to use pecan flour, sunflower flour, or cashew flour, I think these would be fine but haven’t tried, so be sure to report back if you do experiment. Please also report back if you try subbing coconut flour – I think this could work as well, but you’d need much less flour (add just enough to form a dough), because coconut flour absorbs liquid like a sponge.
(For a recipe with regular flour, try these Vegan Peanut Butter Cookies.)
The nut butter:
I’ve made both peanut butter and almond butter cookies from the cookie recipe, or you can use sunflower butter, pecan butter, cashew butter, macadamia nut butter, or this Keto Nut Butter for a low carb option.
The sweetener:
For sugar free cookies, either powdered erythritol or a powdered monk fruit erythritol blend will both work well here.
If you don’t need the cookies to be suitable for a low carb or ketogenic diet, regular powdered sugar is also fine to use.
Stevia, maple syrup, allulose, and granulated sweeteners haven’t been tested in this recipe yet, so be sure to leave a comment if you experiment.

How to make perfect keto peanut butter cookies
Gather all of your ingredients, and grease or line a baking sheet with parchment paper.
Preheat the oven to 325 degrees Fahrenheit. If it’s not already soft and easily stir-able, gently heat up the nut butter until it’s runny.
In a mixing bowl, stir dry ingredients very well to ensure that the salt, sweetener, and baking soda are evenly incorporated.
Stir in the nut butter and milk of choice to form a dough. If your nut butter is unsalted, taste the batter to see if you want to add a little more salt to taste.
Roll into cookie dough balls, place on the prepared baking sheet, and press down with a spoon or fork. (I used a fork to get the classic peanut butter cookie lines.)
Bake on the oven’s center rack for 10 minutes. The cookies should still be underbaked and delicate when you remove the tray from the oven. Let them cool completely, because they will firm up as they cool.
Leftover cookies can be stored in a plastic container for soft and chewy cookies or in a glass container for crispy cookies. They can also be frozen to thaw and eat later.

Three Ingredient Peanut Butter Cookies
If you’re looking to make 3 ingredient keto peanut butter cookies instead of the recipe below, simply stir together 1 cup peanut butter, 1/2 cup granulated erythritol or sugar, and 1 egg or chia egg. (A flax egg will work but is more crumbly.)
Preheat the oven to 325 degrees F. Stir all ingredients to form a batter, shape into cookies, and bake on a parchment-lined cookie sheet for 10 minutes. Let cool completely to let them firm up before handling.

I made this recipe exactly as suggested, only quadrupling it to make enough for a large family. I used an entire jar (2 Cups) of Teddy’s Peanut Butter, and ended up microwaving for 30 seconds and using my immersion blender to get it really nice and smooth. Then when we mixed the dough if just seemed like the spoon wasn’t cutting it but the kids were happy to put on some disposable gloves and mix it together with their hands.
We had 28 cookies when all was said & done, which did include myself and 3 kids snacking on cookie dough!
The final result was perfection! Definitely husband and children approved. I’d be surprised if we have any leftovers by the end of the day.
These taste great! I used Swerve Brown Sugar instead of white powdered sugar and sifted it with the other dry ingredients into the mixing bowl. I like to sift almond flour when using it. Adding brown sugar gave these a nice rich taste.
I also added about a 1/4 teaspoon of vanilla into the wet ingredients. I got 19 small cookies out of a single recipe, but they seem about the standard size for any cookie – not small at all. A really nice recipe. Thank you!
Thank you so much for making them!
Is the one net carb for the large serve of cookie or the small serve? Thanks
Does anyone know if the net carbs are for a serving of 16 or 8?
Thanks
I’ve been baking/living keto for years now. I’ve made some outstanding desserts via other bloggers recipes. These are the most simple and delicious cookies. I will definitely be making these often. Thank you Katie!
I’m wondering why a few people didn’t have luck with these. Perhaps they used baking powder not soda?
Really good cookies. My son and husband also enjoyed them. Followed your recipe exactly and they came out perfectly. Thank you so much for sharing.
Love these! Easy to make. Great flavor. Even my teenagers eat them.
I am curious if anyone has done the nutritional breakdown for them.
Peanutbutter cookies made initially with regular powdered sugar. They were a little crumbly.
I made a second batch using Swerve Brown and they were not crumbly and had a better taste.
The best and super easy. I add more salt, press salt flakes into the top before baking. I also add chopped peanuts(this does add more to carb count). I also cook these till they are slightly browned. Love these. Thank you Katie!
Fabulous! Loved every minute of them!!
I used maple syrup and they came out perfect! Thanks!
