Keto Peanut Butter Cookies
Peanut butter cookies are always a family favorite! There is something about the simplicity of the cookie, or maybe the fork pattern on top, that always makes them a great choice.
But, since my husband started following a keto eating plan (and I want to support him) I've been on a quest to transform our family's favorite desserts into low-carb options that both hit that sweet notes that we know and love love, while also keep the carbs-counts low.
Making 3 ingredient keto peanut butter cookies seemed like the perfect recipe to adapt to our healthy lifestyle. We love these keto peanut butter cookies so much, we even served them as my birthday dessert with Halo top keto-friendly ice cream on the side.
It's not always easy, and often takes a few attempts, but I think I hit this one out of the park! We've experimented with Swerve powdered sugar, Swerve granulated sugar, and even Swerve golden brown sugar to compare and contrast how the change in sweetener impacts the recipe.
Even without the use of traditional peanut butter cookie ingredients, these keto peanut butter cookies will leave you begging for more - and possibly adjusting tomorrows eating plan to allow room. 😉

Ingredient Notes
One of my favorite things about this recipe (besides being just 3 ingredients) is that it uses items that are always in my house! No need to grab something new or specific for this one. Just grab your favorite mixing bowl, preheat the oven, and get ready to bake.
- natural peanut butter
- powdered erythritol
- egg
- vanilla (optional)
Variations
- Peanut Butter - For a variation try chunky peanut butter or other types of nut butters like almond, sunflower, or a mixed nut butter.
Step by Step Instructions
You are going to create your 3 ingredient keto peanut butter cookies in just 3 easy steps!
Prep
Preheat your oven to 350. Be sure your rack is in the middle position in your oven.
Assemble
Combine your peanut butter, erythritol, and egg in a medium-sized bowl using your favorite spatula.
Add in the optional vanilla here as well (just make sure you are using quality vanilla rather than the imitation stuff). Mix until just combined.
Next, line a cookie sheet with parchment paper. Scoop your dough and roll into balls, about 1-inch in diameter.
Press lightly with a fork for the classic criss-cross pattern!
Bake
Place in your preheated oven and bake for 9-10 minutes. I prefer to cook my cookies on the lower end creating a softer finished product. However, as long as you don't exceed 10-minutes, they will still be delicious!
Allow your keto peanut butter cookies to cool for a few minutes before placing them on a cooling rack.
Enjoy!
Recipe Tips
- Adding in ½ to 1 teaspoon of vanilla will up the flavor-factor of these cookies, however it is completely optional!
- Be sure to pre-heat the oven before you dig out your ingredients! This recipe whips up in no time flat.
- Using a cookie scoop will ensure your peanut butter cookies are uniform in size and bake evenly.
- Allowing your egg to come up to room temperature will make it easier to combine.
- Top with crushed peanuts before baking to add a little extra crunch to your cookies.
- This is a great recipe if you are looking to introduce your kids to baking! Super simple and easy for little hands.
Common Questions
Store your keto peanut butter cookies in an airtight container or zippered bag to keep them fresh for up to 5 days.
Oh yes, you can! After allowing your 3 ingredient keto peanut butter cookies to cool completely, place them in the freezer in a single layer for 20-30 minutes. Then transfer them to a storage container or freezer bag and save them for later.
Meaning... you could always whip up a double batch today and freeze half for later.

Kitty says
Absolutely the easiest and best keto peanut butter cookies. I have a small electric grinder that I use to make my powdered sweetener in. I can't say enough good things about this recipe. Thank you.
WholeLottaYum says
You're welcome! I'm glad you enjoyed the cookies!
Cathy says
The dough tasted really good so I was excited to bake them. Sorry, but the end result was inedible and I tossed them. I used powdered Swerve. Is there a better sweetener to use? I was so disappointed!
Deanne Wenger says
Thank you for the great recipes.
On this p.b. cookie recipe - is there an exact carb count?
I need to know for my Son's low carb diet for health reasons.
Thank you, Deanne Wenger
Greg says
Was wondering as many others may be also, where is the nutritional information. I just feel that if anyone is posting recipes that they should provide the information.
Thanks,
Greg
Alisha says
How many carbs per cookie? Thank you!!! & I have low carb almond butter, would that work?
Julie Anne Villanueva says
What is the carb count for these delicious looking cookies? I don't think it is listed, unless I am missing it. Thanks!!!
Jane says
How many carbs per cookie? I have been up and down this entire post and do not see the carb count or nutrition info. That would be extremely helpful. Sorry if I missed this info. Thanks. They are super delicious!
Traci says
Can I use Monk Fruit with erythritol that is not powdered?
WholeLottaYum says
Yes, it can! The only difference is that when you use the sweetener that isn't powdered, it tastes sweeter. I'd recommend cutting the sweetener back a little if you aren't using powdered, OR you can try to powder the sugar yourself in a blender ( I have NOT personally tried to do that but have read of others making their own keto powdered sweetener in that way 🙂
Linda Hix says
Tried these today they are so easy to make, they are delicious a little sweeter then non keto but definitely worth making. I made with crunchy peanut butter.
WholeLottaYum says
Yes, they are a little sweeter than non keto peanut butter cookies, crunchy is my favorite version too!
Veronica says
Did not come out crunchy like a cookie. I used stevia sweetener for baking. Could that have been it? Good flavor but more like a Reese cup. I tried baking a bit longer, 12 min. Didn’t help.
WholeLottaYum says
Stevia is not a 1:1 substitute for monk fruit or erythritol, it's MUCH stronger and more potent.I'm glad it still had great flavor!
