That is one amazing looking AT-AT cake.  It's not entirely edible since the legs and base are wood covered in gum paste but the head and body are edible.  That said I don't know if any edible material would be strong enough to support the body and especially the head.  The details on this AT-AT cake is amazing!  Great job Jennifer Luxmore of Sin Desserts in Providence, RI.
