Rice Krispies Treats
Rice Krispies Treats are a confection commonly made through binding WK Kellogg Co's Rice Krispies or another crisp rice cereal together with butter or margarine and marshmallow. Though they are traditionally home-made, Kellogg's began to market the treats themselves in 1995. Rice Krispies Treats products are currently manufactured and marketed by Kellanova.
History
Rice Krispies Treats were invented in 1939 by Kellogg Company employees Malitta Jensen and Mildred Day "in the Kellogg kitchens in Battle Creek, Michigan as a promotional vehicle for the cereal." Kellogg's began commercially to produce plain and chocolate-based treats under the trademark brand-names of "Rice Krispies Treats", "Squares" and "LCMs" in 1995; however, other manufacturers had offered similar products under variant names prior to this. Kellogg's also offered a breakfast cereal based on the confection from the 1990s until their discontinuation in 2020.Kellogg's presented the recipe as "Rice Krispies Marshmallow Treats" in its newspaper ads--with its classic four ingredients --as early as November 1940. It had appeared even earlier in some supermarket advertisements. The same recipe was used in Kellogg's national advertising in 1941, now named "Rice Krispies Marshmallow Squares." By 1950, Kellogg's published the recipe only slightly changed. By 1955 Kellogg's advertised the confection as "Marshmallow Crispy Treats," listed margarine as alternative to the butter, and eliminated the vanilla.
