Kellogg’s “Sugar Frosted Flakes” were introduced in 1952. They were a sweetened version of their “Corn Flakes” that had been around since 1894. Corn Flakes were created by Will Kellogg for patients at the Battle Creek Sanitarium where he was working with his brother John. Each corn kernel makes about three flakes. In the fall it is harvested and taken to a mill. At the mill, the corn is sifted and rolled then sent to a Kellogg’s factory for the final steps: Cooking, drying, rolling, and toasting. Add the sugar frosting, and viola, Corn Flakes become Frosted Flakes.
