Swiss roll
The cake emerged in the 19th century, probably in France, before spreading to other countries. It is traditionally made from a genoise, generally baked in a large, shallow Swiss roll pan, iced, rolled to form a cylinder, and iced again on the outside. The most common combination is basic yellow sponge cake and chocolate buttercream, though many variations that include chocolate cake, ganache, and icings flavored with espresso or liqueurs exist.
