Bûche de Noël is the French name of a traditional dessert served during the Christmas holidays in France, Belgium, Quebec, Lebanon and several other Christian-populated countries. The cake generally looks like a log ready for the fire.
The traditional bûche is rolled to form a cylinder, and filled with chocolate buttercream. Bûches often have a bark-like texture to offer further realism. This is often done by dragging a fork through the icing. These cakes are often decorated with powdered sugar to resemble snow, tree branches, fresh berries, and mushrooms made of meringue.
In Spanish this dessert is known as Tronco de Navidad. In English, it is called Yule Log. Yule is the pagan holiday from which the Christian tradition of Christmas derives.
