National Cream Cheese Frosting Day is observed worldwide on December 13, celebrating the deliciousness of cream cheese frosting, a popular topping for cakes and cupcakes. The holiday is believed to have been established by Arla, a leader in clean-label cream cheese, although some sources suggest it may also be celebrated on March 31. Cream cheese, invented by American dairyman William A. Lawrence in the 1870s, is a soft cheese made from cream and milk, commonly used in various recipes and as a spread. To celebrate, people often indulge in baked goods topped with cream cheese frosting or try their hand at making it themselves, experimenting with different flavors such as chocolate or orange. The day encourages sharing photos of these treats on social media using hashtags like #NationalCreamCheeseFrostingDay.
