Mix together ingredients for cake until well combined, and cook the cake according to the box instructions. While baking, let the cranberries thaw.

Once cool, frost the cake carefully.

Place cranberries in a large bowl and coat with sugar, stirring gently with your hands. If the sugar is having a hard time sticking, simply roll each cranberry in sugar individually. Decorate the cake with cranberries in whatever design you choose, and serve immediately! This cake goes perfectly with eggnog or hot coco!
