These amazing keto peanut butter cookies are made with natural peanut butter and a touch of sweetener.
They are so very flavorful and wonderfully chewy! The fact that they are flourless makes their peanut butter flavor extra concentrated.

Made with just four ingredients, these cookies are incredibly good. They are sweet (but not too sweet), soft, and chewy.
I make them with natural peanut butter and a powdered sweetener, to ensure a smooth texture. I like to add a few dark chocolate chips on top, and although you could skip those, they take these cookies to the next level.

Ingredients
You'll only need four simple ingredients to make these cookies. The exact measurements are listed in the recipe card below. Here's an overview of what you'll need:
- Egg: I use large eggs in most of my recipes, including this one.
- Powdered sugar-free sweetener: I use erythritol.
- Natural peanut butter: The only ingredients should be peanuts and salt. Make sure you've stirred it thoroughly.
- Dark chocolate chips: As dark as you can go and still enjoy them! I like to use 85% cacao chocolate chips made by Pascha.
Variations
- It's fine to omit the chocolate chips, although they are fabulous in this recipe. If you do omit them, make the cookies pretty by using a fork to create a crisscross pattern. So, after placing the dough balls on the cookie sheet, press on them with the backside of a fork, then rotate the fork 90 degrees and press again.
- Sometimes, I add ¼ teaspoon of pure vanilla extract to the batter.
- One of my daughters likes to add a pinch of cinnamon. I'm not a fan... but she loves it.
Instructions
This is such an easy recipe. Scroll down to the recipe card for detailed instructions. Here are the basic steps:
Lightly whisk an egg, then add the sweetener. Mix with a rubber spatula, then whisk until smooth.
Next, add the peanut butter and mix well using a rubber spatula. The mixture will be very thick.
Measure 1.5 tablespoons per cookie (using a cookie scoop) and shape them with your hands into a ball.
Arrange the dough balls on a parchment-lined cookie sheet and gently flatten them with your hands. Gently press a few chocolate chips onto the top of each cookie.
Bake the cookies until their edges are beginning to darken, about 15 minutes in a 350°F oven. Cool the cookies in the pan, then remove them to a cooling rack.
Expert Tips
- If your peanut butter is unsalted, add ¼ teaspoon of salt. The peanut butter I use is quite salty, and the saltiness comes through in the cookies and enhances them.
- It's important to let the cookies cool on the cooling rack and not in the pan. That’s how they get a proper cookie texture. If you leave them on the pan, they will be too soft. This is what they should look like on the inside when ready to enjoy:
Recipe FAQs
I use Whole Foods' natural creamy peanut butter. It's salted, and there's no added sugar. The only ingredients are peanuts and salt.
It's important to mix the peanut butter well before using it. It's also best to use a fresh jar. Natural peanut butter at the bottom of the jar tends to be too dry to bake with, even if you mixed it well when you first opened the jar.
It's best to use a powdered sweetener to ensure the cookies have a smooth, non-grainy texture.
While I usually use stevia in my recipes, I have experimented and found that these cookies need the volume and texture of a powdered sweetener to succeed.
While this recipe should work in terms of texture with any smooth and creamy natural nut butter, the flavor will be very different.
If you do use almond butter, check the consistency of the batter. It should be very thick and dough-like. If it's too liquid, add 1-2 tablespoons of almond flour.
Serving Suggestions
Much like almond flour cookies, keto peanut butter cookies are lovely with tea (or iced tea), coffee (or iced coffee), keto hot chocolate, or a tall glass of cold almond milk.
When I make them without chocolate chips, I sometimes turn them into sandwich cookies and add a layer of chocolate hazelnut spread in the middle.
Storing Leftovers
The leftovers keep well for up to three days in an airtight container on the counter. You can also refrigerate them in an airtight container for up to five days. Remove them from the fridge 30 minutes before serving.
You can also freeze these cookies in freezer bags for up to three months. If layering them, separate the layers with wax paper.

Keto Peanut Butter Cookies
Ingredients
- 1 large egg
- â…“ cup powdered erythritol
- 1 cup peanut butter natural, smooth
- â…“ cup dark chocolate chips
Instructions
- Preheat your oven to 350°F. Line a cookie sheet with parchment paper.
- In a medium bowl, lightly whisk the egg, then add the sweetener. Mix with a rubber spatula, then whisk with a wire whisk until smooth.
- Add the peanut butter and mix well using a rubber spatula. The mixture will be very thick.
- Use a cookie scoop to measure 1.5 tablespoons of dough per cookie. Shape the dough portions with your hands into balls.
- Arrange the dough balls on the prepared cookie sheet, 1-inch apart, and gently flatten them with your hands.
- Gently press 6-7 chocolate chips onto the top of each cookie.
- Bake the cookies until their edges are beginning to darken, about 15 minutes. Cool the cookies in the pan for about 10 minutes. They will be too soft to remove from the pan at this point.
