It is not clear what the origins of National Cheesecake Day are, according to the website Holiday Insights. As for the history of cheesecake itself, the beloved dessert may have first been made in ancient Greece and eaten by athletes during the first Olympic Games, although it would have looked and tasted somewhat different from today’s cheesecake. Ingredients were more Spartan, generally including just flour, honey, and cheese, according to

The Romans subsequently modified the recipe, and cheesecake was further adapted as it made its way to European countries during the Middle Ages. It was not until 1872 that cream cheese was developed, allowing for the creation of the classic cheesecake that we know and love today.
