To dream of frosting represents preoccupation with things that only feel good. Experiencing new creativity, prolonged success, or renewed self-assurance. Enjoying new opportunities catered to you. Enjoying feeling that you can't lose. Pleasure that is all about you.
Negatively, frosting may reflect a superficial or "winner only" attitude. So concerned with winning that you don't care about other people's feelings. It may also be a sign that you need to look deeper to find the truth of a matter. Beauty with no substance.
