Keto Peanut Butter Cookies {3 Ingredients}
These easy keto peanut butter cookies will be your go-to cookie recipe to have on hand- they need just 3 ingredients! Made with just peanut butter, a low carb sweetener and with or without eggs, these easy peanut butter cookies sweet AND salty! No flour, No sugar!
These flourless peanut butter cookies are just like your grandma’s peanut butter cookies, but so much healthier! They are perfect for cookie swaps, Christmas cookie bake-offs or a healthy dessert any day of the week.
I’ve been making batch after batch of them, especially with Christmas just a few weeks away. What I love about these cookies are just how easy they are to make- No chilling, one bowl and 12 minutes. I also LOVE how long they keep- I can make them a week in advance and they still have the fresh, soft and chewy taste the entire time.
For a keto cookie recipe, this is easily the easiest and quickest to make. Although the keto chocolate chip cookies, keto brownie cookies, and double chocolate chip keto cookies are just as easy…
3 ingredients, 12 minutes, NO excuses. Soft, chewy and slightly dense on the outside….no words.
How to make keto peanut butter cookies
No mixing bowls, multiple dishes or blenders needed- Just one bowl and a sturdy wooden spoon!
The ingredients
- Peanut butter. Smooth, drippy peanut butter is best. Aim for the all-natural kind, with no added sugar.
- Granulated sweetener of choice. Either monk fruit in the raw or swerve will work. These are keto-approved and have the same consistency and taste of white sugar.
- Egg OR ground chia seeds. Either one large whole egg or to keep it vegan and eggless, ground chia seeds. This does NOT need to be made into a ‘chia egg’.
The directions
- Preheat the oven to 180C/350F. Line a large baking tray or Silpat cookie sheet and set aside.
- In a large mixing bowl, combine all your ingredients and mix until a thick batter remains.
- Using a cookie scoop, form 12 small balls of dough and place on the lined pan, 2-3 inches apart. Press each ball of cookie dough into a circular shape, before pressing down with a fork on each one.
- Bake cookies for 10-12 minutes, or until golden on the edges. Remove cookies from the oven and allow to cool completely. Dip in chocolate, if desired.
How many carbs in keto peanut butter cookies
Peanut butter cookies are ridiculously low carb and low-calorie dessert. Each cookie yields 80 calories and contains 3 grams of carbs with 1 gram of fiber- This means each cookie is 2 grams net carbs!
Recipe Substitutions and Dietary Swaps
- Vegan Peanut Butter Cookies. Instead of using the whole egg, use 3-4 tablespoons of ground chia seeds. Start with 3 tablespoons then add one more if needed.
- Paleo Peanut Butter Cookies. Swap out the peanut butter of either smooth almond butter or smooth cashew butter.
- Nut-Free Flourless Cookies. Use sunflower seed butter or tahini to replace the peanut butter.

Can these be made with granulated erythritol?
Sure can! I often make it with Swerve 🙂
I made these with monk fruit sugar (100% monk fruit extract powder with no erythritol) and they are extremely crumbly 🙁 waste of ingredients.
Perhaps it was the brand you used- it’s been made thousands of times successfully- I think errors come down to the ingredient brand used: )
Which brands do you recommend? I am making for a friend and just want to use what has been known to be successful.
Hi Emily! Honestly, any creamy peanut butter is best- I love Wholefoods brand, Kraft (creamy/smooth) and American style smooth.
These were way too sweet. I think 1/3 cup of monkfruit would be more than enough.
Hi Gillian, I’d double check the brand you used, you may have used one that has a more intense sweetness- Definitely cut down next time 🙂
