Please help me answer this question. I'm new to cake decorating, I will be transporting a cake, which will consist of a small 3-D cake on top of a sheet cake. When I go to separate the 3-D cake from the sheet cake. ( the 3-D cake will be brought home by the birthday person as we cut up and eat the sheet cake) How can I prevent the frosting from sticking to the bottom of the 3-D cake as I lift it off the sheet cake. I don't want to serve pieces of unfrosted cake to everyone. i will be transporting the cake to a large gathering at a resturant. So I don't want to bring a lot of extra stuff to fix up the sheet cake. Thanks for your help 
could treat 3-d cake as an elevated tier and use pillars to separate it from sheet ---
examples of pillars (wilton products) --
little globes (the pillars can be trimmed down)http://www.wilton.com/store/site/product.cfm?id=01BC340D-802D-F658-0CD45CAA252EAB95&fid=01BC342C-802D-F658-04F75CC3D5E68FDD
the ones from the course 3 kit:

hidden style (also the ones inside the globe set)

that way only holes in cake from pillars.
in the case of the hidden ones -- the gap could be filled w/ flowers or similar.
HTH
If you really want the 3D to sit right on top, sprinkle the icing on the sheet cake with powdered suger before placing the 3D on top. This should help some. Also, I would take a container and spatula with extra icing to spread over the ckae if the frosting does still lift. This way, guests will all get an inced piece. HTH!!
A class I took taught us to put either grated coconut or cake sprinkles between layers. I find the sprinkles to be the best (not evryone likes coconut). I works great.
Are you talking about the jimmies?
Yes.
My suggestion would be to put some icing in a zip top bag or a piping bag. Snip the corner or tip of the bag and apply where frosting was lifted.
