National Marshmallow Day is a celebration dedicated to the sweet and fluffy confection known as marshmallows. It is observed annually and dates back to the early 1900s when marshmallows were first commercially produced in the United States. This food day honors the versatile nature of marshmallows, which can be enjoyed on their own, roasted over a campfire, or used as a key ingredient in various desserts and snacks. Marshmallows are made from a mixture of sugar, water, gelatin, corn starch, and flavorings, creating a soft and airy texture loved by many. National Marshmallow Day is a fun way to indulge in this beloved treat.
