My son wanted Gotham City for his Batman 3rd birthday party. My first attempt at color flow...good thing I stated a week in advanced for the buildings to dry. The buildings were quite labor intensive, not real straight and I had alot of crackng while they dried. It was a big hit though...the kids each took home the buildings, they had enough sugar at the party. This cake was huge, I had 1/2 left over after serving 22, and some had seconds.
