A Christmas cake is a special type of cake that is traditionally made during the Christmas season. It is usually a fruit cake, which means that it is made with a variety of dried fruits and nuts. The most common fruits used in a Christmas cake include raisins, currants, and dates. The nuts can include walnuts, pecans, or almonds. Some people also add spices such as cinnamon, nutmeg, and cloves to the cake. The cake is then usually covered in a layer of marzipan, which is a sweet almond paste, and then decorated with a layer of icing.
