After you’ve tasted them, these old-fashioned chewy peanut butter cookies will be forever in your memory, too. And if you scan the comments at the bottom of this post, you’ll see a whole lot of people calling these the Best Peanut Butter Cookies Ever.

While the origin of these peanut butter cookies is sometimes debated, the recipe has certainly been around longer than I have. I can remember seeing the instructions on the side of Jif, Skippy, and Peter Pan peanut butter jars throughout my childhood.
