National S'mores Day celebrates classic American campfire treat

National S'mores Day is observed annually on August 10th in the United States. The dessert, a combination of roasted marshmallows, chocolate, and graham crackers, is deeply associated with American camping culture.

The treat's origins date back to the 1920s, with the first known recipe appearing in a 1927 Girl Scouts handbook. It was originally referred to as "some mores." While not an official public holiday, the occasion is recognized by the National Confectioners Association.

Consumer data indicates that Americans purchase approximately 90 million pounds of marshmallows each year, with an estimated 50 percent of summer marshmallow sales being used for s'mores. Variations of the classic recipe include additions such as peanut butter, strawberries, or salted caramel, and some versions substitute graham crackers with chocolate chip cookies.
