I have a customer who wants a white chocolate raspberry cake I make but wants chocolate frosting. My cake I use raspberry flavoring.. not real raspberries.    The flavor combo is throwing me off and I guess its because of the white cake with raspberry and chocolate frosting.  I was going to make a dark chocolate ganache icing to set off the cake.... any thoughts?? Do you think this will taste alright?

AWhite chocolate layers, raspberry filling (the real thing, not any flavoring - it's quite a stretch to call something raspberry if it doesn't even contain the real thing) and dark choc icing.

that's exactly what I was thinking of doing... thanks so much.  I find that the clients I deal with prefer this option more than when I make it with real raspberries.  They like the white cake instead of the colored cake you get using real raspberries.  My clients always have the option of the real thing or a flavoring.
