 In his 1925 research bulletin called "How to Grow the Peanut and 105 Ways of Preparing it for Human Consumption", he included three recipes for peanut cookies calling for crushed or chopped peanuts.It was not until the early 1920s that peanut butter was listed as an ingredient in the cookies.Early peanut butter cookies were either rolled thin and cut into shapes, or else they were dropped and made into balls; they did not have fork marks.
