Classic at Christmas time, the Buche de Noel is a traditional French dessert, consisting of layers of sponge cake and cream that have been rolled in the shape of a log. The combination of moist cake, whipped cream filling, and a generous dusting of powder sugar on top are layered together by delicately folding the cake to form the jellyroll. To prevent cracks, take your time while rolling the cake, and use a towel to help the Christmas Buche take shape.
