This was a cake I made for our school Christmas party. The bottom tier is a humminbird cake with lemon cream cheese frosting, and the top tier is yellow cake with eggnog frosting. The cityscape enclosure is gumpaste with fondant accents, and the nativity scene is a mix of fondant and gumpaste. Inspiration for the cake came from CC member 'dittle': http://cakecentral.com/g/i/3144773/birthday-cakes/
I didn't change very much, because the original is such a great cake, but I thought it would make a perfect setting for a Christmas nativity.
