Peanut Butter Cookie Ingredients
You'll only need 3 simple ingredients for these delicious peanut butter cookies!
- Peanut butter - natural unsalted peanut butter that has no added sugars. Check the nutritional information carefully because lots of store-bought peanut butter have added sugar.
- Erythritol - to help add sweetness to the cookies, we'll use Erythritol. Feel free to substitute with any of your preferred sugar-free sweeteners.
- Egg - one large, preferably free-range egg at room temperature to help bind everything together.
How To Make Keto Peanut Butter Cookies
- Preheat your oven to 350 degrees Fahrenheit (180 degrees Celsius) and line a baking tray with baking paper.
- In a mixing bowl, combine the peanut butter, egg, and Erythritol.
- Use a spatula (or your hands!) to mix the ingredients together thoroughly until it forms cookie dough.
- Shape the dough into balls in the palms of your hands. I made 15 cookies with this recipe, and I feel they were a perfect size.
- Transfer the balls onto the lined baking tray leaving space in between each ball.
- Decorate the cookies. Press down on the balls with the back of a fork. You can also use the back of your hand or experiment with various other shapes for different patterns!
- Bake the keto peanut butter cookies for 10 minutes until golden brown.
- Allow the cookies to cool to room temperature, and then serve!
These cookies really turned out delicious and I'm sure you're going to love them, enjoy 🙂

- To store: Keep leftover peanut butter cookies in an airtight container or jar at room temperature. They'll stay fresh for up to 2 weeks, and you can even place them in the refrigerator, where they'll keep for up to 1 month.
- To freeze: You can make a large batch of these cookies and freeze them for longer storage. It's a great way to meal prep, and you can pop them in lunch boxes straight from the freezer. Place the cookies between sheets of baking paper in a freezer-proof bag or container. They'll keep in the freezer for up to 6 months (if they last that long!)

Is it possible to substitute Xylitol for the sweetener?
Hi Rita! Yes, you'd use 1/2 a cup of Xylitol instead of 2/3 cup of Erythritol. Enjoy!
What can l substitute for peanut butter. Copha or cacco butter perhaps. Would be good to have alternatives for those with nut allergies.
Hi Sandy! Yes! You can also use sunflower butter and almond butter (if you aren't allergic to tree nuts!). Should be just as delicious!
Can you I use stevia?
Hi Erika, yes you can use stevia. For this recipe, you'd use around 6 tsp of stevia instead of 1/2 cup of Erythritol. Hope that helps!
Thanks for all the great recipes! Could you help me out figuring out converting these measurement to grams.
Sure, no problem. I've updated the recipe and you'll need 250 grams of peanut butter and 135 grams of Erythritol. Enjoy!
Peanuts aren’t Keto friendly, this recipe contains almost 13 grams of carbs per cookie.
Hi Courtney, natural peanut butter is very keto friendly.
The cup of peanut butter used in this recipe contains 43.5 grams of carbs with 15.6 grams of fiber, so 27.9 grams of total net carbs.
The other carbs in the cookies come from Erythritol, and they are actually alcohol sugars which are zero calories and carbs.
The recipe makes 15 cookies, so it ends up being just under 1.9 grams of net carbs per cookie.
Hope that helps!
What can you use in place of Erythritol
You can use any other sugar-free sweetener you have available. Xylitol, stevia, monk fruit and allulose will work.
I thought you said on another page that we should stay away from peanut butter. Can these be made with almond butter?
Hi Vivianne! Natural peanut butter is perfectly fine to use on keto, you need to stay away from peanut butter with added sugars.
Make sure to check the nutritional information on the peanut butter you buy and just opt for the ones that only contain peanuts.
And yes, you can use almond butter for these cookies as well!
