Rice Krispies Treats (also called Rice Krispie Treats, Marshmallow Treats, Marshmallow Squares, or Rice Krispies Squares in the United Kingdom & Canada, and LCMs in Australia) 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.[1] 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."[2] Kellogg's began commercially to produce plain and chocolate-based treats under the trademark brand-names of "Rice Krispies Treats" (in the United States and Mexico), "Squares" (in Canada, the United Kingdom and Ireland) and "LCMs" (in Australia and New Zealand) in 1995; however, other manufacturers had offered similar products under variant names (such as "Crisped Rice Treats" or "Marshmallow Treats") prior to this. Kellogg's also offered a breakfast cereal based on the confection from the 1990s until their discontinuation in 2020.
