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. 😉

Step by Step Instructions
You are going to create your 3 ingredient keto peanut butter cookies in just 3 easy steps!
Preheat your oven to 350. Be sure your rack is in the middle position in your oven.
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!
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.
- Adding in 1/2 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.
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.

- 1 cup natural peanut butter
- 1/2 cup powdered erythritol
- 1 egg
Preheat the oven to 350F and make sure the oven rack is in the center position.
In a medium-sized mixing bowl, add the peanut butter, egg, and powdered erythritol. If you have vanilla, adding 1/2-1 tsp is a nice addition but totally optional.
Mix the ingredients together until just blended.
Form the peanut butter cookie dough into small balls and put them on a parchment paper-lined baking sheet.
Gently flatten the cookie dough balls with a fork to make criss-cross lines.
Bake for 9-10 minutes until the cookies are baked through.
Let the cookies cool for 5 minutes before removing them from the baking sheet.
For a variation try chunky peanut butter or other types of nut butter like almond, sunflower, or a mixed nut butter.
Natural peanut butter is recommended for keto, many brands include sugar in them and that will make the carbs too high.
Powdered erythritol or monk fruit works best in the recipe, if you only have granulated we recommend cutting back on the sweetener slightly or making your own powdered sweetener by pulsing the granulated sweetener in a high powered blender.
