Since these Keto Peanut Butter Cookies are fun and easy to make, they make a great activity to do with kids, even toddler-aged aspiring bakers. Plus, the batch makes a huge quantity, especially if you use a tablespoon size scoop as we did. We suggest using over a cup of crushed salted peanuts to roll them in. As a result, the texture and mouthfeel when biting into them is both mouth-watering and memorable. Our batch made 64 cookies.

Our inspiration was King Arthur Baking Company‘s recipe for Keto-Friendly Salty-Sweet Peanut Butter Cookies, via Melanie Wanders.
