I don't know about you, but peanut butter cravings are a real thing around here.
The love affair began as a child it is something that I never outgrew. There is just something about the nutty goodness that never fails to delight.
If you like peanut butter as much as I do, you are going to go wild for these super-simple Low Carb Peanut Butter Cookies. With just seven ingredients, these babies deserve to become a habit.
Variations and Tips
- I used Swerve brown sugar. Surkin Gold is another brand that I have used and liked. If you don't have either and don't want to pick up a new sweetener, Swerve confectioners works in this recipe as well.
- Remember that all ovens cook slightly differently, so pay attention to how the cookies are looking towards the end. They can burn quickly!
- You can adjust the cooking time for a chewier versus crisper cookie. At 10 minutes, they are still fairly chewy. They will harden as the days go by, though.
- For a fun twist, try adding in chocolate chips.
Selecting Peanut Butter
Make sure that you read the label of your peanut butter if you are following a keto diet. Some brands have added sugar. I like to get fresh peanut butter that is ground at the store with nothing else added in when I can. If not, I just go with whatever I can find that is the lowest in carbs.
Adjusting Consistency
Peanut butter brands vary in how liquid they are. If you feel you need a touch more moisture, you can add in heavy cream, 1 tablespoon at a time. Just be careful not to overdo it! The mixture should be crumbly, but come together into balls easily.

In case you're wanting to substitue monkfruit sweetener for the Swerve, be sure to decrease it to 3/4 cup. I used a full cup and the cookies were good but WAY too sweet!
