Roll Cake Day, also known as Swiss Roll Day, is observed in Sweden every August 9. This celebration honors the rolled sponge cake, known as rulltårta in Swedish, which has been a popular dessert since the 1920s. The cake, typically filled with buttercream and strawberry jam, is often served with coffee and comes in various elaborate forms, including a chocolate version called drömrulltårta. The origins of the roll cake are believed to trace back to Central Europe, with its first mentions in English and American cookbooks appearing around the mid-19th century. Since its inception in 2012, Roll Cake Day encourages people to bake and share roll cakes, making it a delightful occasion for cake lovers worldwide.
