Fun facts about rice crispy treats:
The Invention Story
Rice Krispies Treats were first created in 1939. Two Kellogg Company employees, Malitta Jensen and Mildred Day, invented them. They worked in the Kellogg kitchens in Battle Creek, Michigan. The treats were made to help promote the Rice Krispies cereal. It was a tasty way to show how versatile the cereal could be!

Early Recipes:
Kellogg's shared the recipe for these treats in newspaper ads as early as November 1940. The first recipe was called "Rice Krispies Marshmallow Treats." It had four main ingredients:
1/3 cup butter
1/3 cup marshmallows
1/2 teaspoon vanilla
One 5-1/2-ounce package of Rice Krispies
This recipe also appeared in some supermarket ads even earlier. By 1941, Kellogg's national ads used the same recipe, but called the snack "Rice Krispies Marshmallow Squares."

Recipe Changes in the 1950s:
The recipe changed slightly over the years. By 1950, Kellogg's published a new version.
It used:
1/4 cup butter,
1/2-pound marshmallows,
1/2 teaspoon vanilla,
5 cups of Rice Krispies.
By 1955, the company advertised the snack as "Marshmallow Crispy Treats." This version suggested using margarine instead of butter. It also removed the vanilla. The recipe then was:
1/4 cup butter or margarine
1/2-pound marshmallows
5 cups of Rice Krispies
Some snacks taste good. 👀
Rice Krispies Treats taste like childhood, hope, and the strength to get through a Wednesday.
