Answer:
Rice Krispies treats are a well-known sweet snack which has been in the United States since the late 1930s or early 1940s. A Kellogg Company employee named Mildred Day first made the dessert to raise money for the Campfire Girls, with the recipe being published in 1941. Since that time, Rice Krispies treats have been a staple of after-school snacks, bake sales, and children’s parties.
