A cake roll, also known as a Swiss roll, is a type of dessert made from a thin sponge cake that is baked in a flat sheet. Once cooled, the cake is spread with a filling, often made of jam, cream, or frosting, and then carefully rolled up into a cylindrical shape. The outer layer can be dusted with powdered sugar or coated with chocolate for added flavor. Cake rolls are popular for their versatility and can be made in various flavors, such as chocolate, vanilla, or red velvet. They are often served at celebrations, including birthdays and holidays, and can be decorated to suit different occasions.
