National Peanut Butter Cookie Day is observed in the USA on June 12 every year. This holiday celebrates one of America's favorite cookies, which has its roots in the work of George Washington Carver, who developed numerous uses for peanuts, including recipes for peanut cookies. The first printed recipe for peanut butter cookies appeared in 1932 in the Schenectady Gazette, although the recipe likely existed prior to that. The traditional preparation involves rolling the dough thinly and creating a distinctive crisscross pattern on top with a fork. To celebrate, many people bake peanut butter cookies, often using family recipes, and share them with friends and family.
