I am doing some cakes for my mom for her job and they want one of them to be a mousse cake but want their logo on top of it. I don't think it is possible to cover this type of cake in fondant because of the weight. I was reading online that you could use molding chocolate like fondant and cover cakes with that. Will this be to heavy as well? And if neither of these work, are there any suggestions on how I could decorate this type of cake? I am a newbie to all this so any suggestions are greatly appreciated. Thanks
