Caramel Cheesecake Day, observed worldwide every September 10, celebrates the creamy dessert topped with caramel sauce. The holiday highlights the evolution of cheesecake, which has been made with fresh cheese since ancient times, but the modern version emerged in the 19th century. Caramel Cheesecake Day is one of several cheesecake-themed holidays established by Patti Jewel and her team at HolidaySmart, with its inception in 2010 following the original Cheesecake Day created in 1985. To celebrate, people often enjoy slices of caramel cheesecake, either from bakeries or homemade, with many opting for no-bake recipes. A popular way to share the celebration is by posting pictures of their creations on social media using the hashtag #CaramelCheesecakeDay.
