History: Kellogg’s Rice Krispies Treats were invented in the 1930s. Iowa State University of Science and Technology officially credits the development of Rice Krispies Treats to Mildred Day, who died in June 1996 at the age of 92. She worked for the Kellogg Company and used the cereal to develop the snack as a fundraiser for a Camp Fire Girls fundraiser. The recipe was first published in 1941 and has been such a success that Kellogg’s has been selling a premade version of Rice Krispies Treats for the last ten years.
