soni2006, if you would still like an answer, try something like this.
Bake a cake (carrot is nice with added candied fruits and golden raisins and pecans or walnuts) of your choice in either a round or rectangular pan. (I have used a spice cake or carrot cake boxed mix with the added ingredients and it is delicious.)
Cool and then level the cake top with a long serrated knife. It does help to refrigerate the cake for 15-20 minutes before trying this. Just slice the 'hump' of the top of the cake so it will be more level and sit straight for the frosting and decoration.
Frost with a cream cheese frosting, rum flavoring added. Don't put it on smoothly but rather like small indefinite circles and lifted points to the frosting.
While the icing is still wet, sprinkle the top with edible glitter for a beautiful Christmasy sparkle. (Available at hobby stores with cake supplies or online. And you can find recipes to make your own online. Do search for 'edible glitter' using gum arabic and water.)
If you have some silk holly leaves or a poinsetta top the cake with that when frosting hardens. Additionally, you could put on some tiny Christmas charms - angels, bulbs, giftbox, drums etc - around the top or bottom edge.
It will taste and look very intriguing and be as Christmasy as you wish to make it.
