I am wanting to make a 9" round Louis Vuitton cake.  How do I make a dark brown buttercream icing b/c I don't want fondant?  Also, anyone have a printable stencil they can share for the logos?  I need to have this cake finished by 8-24 so any quick answers would be appreciated.

I have made dark brown buttercream by just adding brown gel color.  You can get LV edible images or stencils through Amazon.
