The peanut butter cookie was invented in the 1910's, when George Washington Carver of Alabama's Tuskegee Institute published a peanut cookbook in an effort to promote the crop. In the cookbook titled, "How to Grow the Peanut and 105 Ways of Preparing it for Human Consumption," Carver included several cookies recipes that called for chopped peanuts. Peanut butter was added to the cookies 20 years later along with the fork marks that are associated with the cookie today.
