Peanut butter cookies

A peanut butter cookie is a type of cookie that is distinguished for having peanut butter as a principal ingredient. The cookie originated in the United States, its development dating back to the 1910s. George Washington Carver , an American agricultural extension educator, from Alabama's Tuskegee Institute, was the most well known promoter of the peanut as a replacement for the cotton crop, which had been heavily damaged by the boll weevil. He compiled 105 peanut recipes from various cookbooks, agricultural bulletins, and other sources. 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 1930s that peanut butter was listed as an ingredient in the cookies.
