The best keto peanut butter cookies are made with smooth natural peanut butter, a keto sugar replacement that needs to be powdered and one egg. These are all the ingredients you need to make some sugar-free peanut butter cookies that are also paleo friendly.

You can add a fourth ingredient to bring these peanut butter cookies to the next level: unsweetened dark chocolate chips. Everyone will love these easy keto peanut butter cookies.

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:

  1. Process the keto sugar replacement into a coffee grinder or a Nutribullet until it turns into a powder. If you have powdered sweetener in your pantry skip this step.
  2. Combine well all the ingredients in a large bowl.
  3. Using a spoon scoop out the dough and make 1-inch bowls. Place them on a lined baking sheet with parchment paper. Use a fork to create that crisscross shape on top of each cookie.
  4. Bake them for about 10-12 minutes or until they look done on top and start to smell incredibly delicious.

A few tips

  • Let the keto 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 keto peanut butter cookies 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 sweetener to use for the keto peanut butter cookies?

You’ll need to use a powdered sweetener. I love to use Swerve confectioners low carb, keto sweetener and blend in a food processor until it looks like a powder.

You can use monk fruit sweetener too but the keto cookies will be sweeter as this sweetener has

Don’t use STEVIA when baking because it makes the cookies bitter.

Granulated sugar is ok to use too be the texture will be different as you’ll feel all the granules when chewing.
