I've seen a lot of penguin/igloo cakes, but everyone puts their own style into theirs. This is mine.
10" base cake with 6" cake, carved into igloo. All covered with fondant. Penguins are modeled from fondant. Trees are gumpaste finished with sanding sugar, drizzled with icing which was then painted with gold dust. colored dragee tree decorations are the only thing not hand made. You can't really tell from the pic, but base cake, igloo and snowballs are all dusted with pearl dust.
