Bûche de Noël, or Yule log, is a traditional French dessert served during the Christmas season. It is typically made from a sponge cake that is rolled and filled with cream, often flavored with chocolate or coffee. The cake is then decorated to resemble a log, complete with bark-like textures and festive embellishments. This dessert has its origins in the ancient custom of burning a log in the fireplace to celebrate the winter solstice. Over time, the practice evolved into a sweet treat, symbolizing warmth and family gatherings during the holiday season.
