Keto Peanut Butter Cookies

  • Author: Nate Dadosky
  • Total Time: 15 minutes
  • Yield: 8 cookies 1x


Super simple keto-friendly peanut butter cookies ready in 15 minutes flat!




  1. In a large bowl, thoroughly mix together the egg and sweetener with a sturdy mixing utensil.
  2. Add the peanut butter and mix for 2 minutes until completely combined (mixture will thicken).
  3. Roll mixture into a log (about 2 inches in diameter) on a parchment-lined sheet pan and cut into 8 equal disks.
  4. Arrange the disks on the sheet pan and press down gently to flatten slightly (see notes). Bake at 400°F for 10 minutes (bake on the middle rack/center of the oven to prevent burning).
  5. Remove from oven and use the back of a fork to make a crosshatch pattern on each cookie while they’re still hot.
  6. Let cool completely (at least 15 minutes) and enjoy!

These cookies won’t melt and spread while baking like traditional cookies do, which is why you need to flatten them slightly before they go into the oven.

If you have a silicone baking mat, I would recommend using that instead of, or in addition to, parchment paper to ensure the bottoms of the cookies don’t burn.

Optionally, you can add some vanilla extract, chocolate chips and a pinch of salt (if your peanut butter isn’t salted) to make these cookies extra delicious!
