How to Make Keto Peanut Butter Cookies?
The instructions for this recipe are pretty easy for this recipe. Here’s all you have to do:
- Process Erythritol or Monk-fruit into a coffee grinder or Nutribullet until it turns into a powder. If you have powdered sweetener in your pantry, skip this step.
- In a large bowl, combine well all the ingredients
- Using a spoon scoop out the dough and make 1-inch cookie balls.
- Place them on a lined baking sheet lined with parchment paper. Use a fork to create that crisscross shape on top of each cookie.
- Bake them for about 10-12 minutes or until they look done on top and start to smell incredibly delicious.
These keto cookies are ready in 20 minutes with minimal effort and are super soft and chewy.

Tips for the Best Flourless Peanut Butter Cookies
- Let the peanut butter cookies cool down for at least 15 minutes before serving as they are very crumbly straight out of the oven.
- If after combing all the 3 ingredients for the low carb peanut butter cookies and the dough looks too sticky, refrigerate for 10 minutes before rolling it into delicious cookies.
- Make sure that the cookies don’t touch because they slightly spread when cooking.
- Don’t try to add any kind of flour, because these are flourless cookies that need only 3 ingredients.
- You can substitute the peanut butter with any unsweetened nut butter such as almond butter or cashew butter.
What’s the Best Sweetener to Use for the Keto Peanut Butter Cookies?
You’ll need to use a powdered sweetener. I love to use Swerve Confectioners sweetener and blend in a food processor until it looks like a powder.
You can use Monk Fruit Sweetener and adjust the quantity to your taste.
Don’t use STEVIA when baking because, in my opinion, it makes the chocolate cookies bitter.
