History of Rice Krispies Treats Day

The exact origins of Rice Krispies Treats Day are not well-documented, but the treat itself has a rich history. The original recipe was created in 1939 by Kellogg's home economists Mildred Day and Mary Barber as a fundraising project for the Camp Fire Girls. The simple combination of melted marshmallows and butter mixed with Kellogg's Rice Krispies cereal quickly became a national sensation, appearing on the back of cereal boxes and in countless cookbooks.

Over the decades, Rice Krispies Treats evolved from a homemade snack into a commercially produced product. Kellogg's introduced pre-packaged Rice Krispies Treats bars in the 1990s, making the treat even more accessible. The day dedicated to these treats likely emerged as a grassroots celebration among fans, with September 18 becoming the unofficial date to honor this iconic American confection.
