Chocolate Day is observed in Sweden every November 11, celebrating the beloved treat of chocolate and chocolate-based products. The holiday has been celebrated since at least 2011, providing an opportunity for Swedes to indulge in their favorite chocolate desserts, such as chocolate balls (chokladbollar) and chocolate mud cake (kladdkaka). The history of chocolate in Sweden dates back to the establishment of the first chocolate factory in 1873, a subsidiary of the Danish company Cloetta. Other notable chocolate brands, such as Marabou, originated from factories founded in the late 19th and early 20th centuries. Chocolate Day is an unofficial holiday that highlights the popularity of chocolate, which has become one of the world's most consumed foods, particularly in desserts.
