So...I was talking about making a chocolate cake today at work. Now...everyone wants me to bring one in on Monday. I want to make a 9x2 and and 8x2 or 7x2 and stack them. I am also thinking that I want to torte each cake.

For fillings, I wanted to do a chocolate ganache in one layer, raspberry in one layer and maybe a white chocolate in the last layer?

For frosting...I don't know what to use.

What does everyone think about this and does anyone have suggestions?

I think your co-workers are very lucky

Don't have any suggestions for frosting with that many different filling flavors....

This will give you a bump.

I the Kraft cooking magazine they made a cake I wanted to try, but haven't yet. They made a chocolate cake torted. The fillings were the frosting and they didn't frost the outside of it. Imagine this....

chocolate layer - green frosting with mint flavor
chocolate layer - yellow frosting with lemon flavor
chocolate layer - pink frosting with strawberry flavor
chocolate layer - chocolate frosting with cocoa flavor as the top

It was all done with pastel colors and it was really pretty. Maybe you can go to the kraft website and do a search for it. I can't find the book right now, sorry.
I'm not sure if this is what you were asking for

When I make a chocolate cake with ganache and raspberry I usually put the very tiny chocolate chips or sometimes i put shavings of white chocolate.

and I cover the whole cake with ganche

I was thinking about covering the whole cake in ganache, but I was curious if that would be just too much of an overload
