I made this for my sister. The igloo is a 6in dome, and the rest of the cake is a one layer 12in round. It is frosted in buttercream. The only fondant is the igloo's opening and the tummies of the penguins. The black and orange parts of the penguins are chocolate clay. The trees were those thick pretzel sticks, covered with buttercream frosting. Then I sprinkled clear sprinkles over the whole thing to make it sparkle like snow. This was so fun to make!!!
