Yule log

A Yule log or bûche de Noël is a traditional Christmas cake, often served as a dessert, especially in France, Belgium, Luxembourg, Switzerland, Lebanon, Vietnam, and Quebec, Canada. Variants are also served in the United States, United Kingdom, Cambodia, Scandinavia, Portugal, Spain, and Japan. Made of sponge cake, to resemble a miniature actual Yule log, it is a form of sweet roulade. 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.
