This may be a strange question, but I have never done this: I have a customer who wants a cake covered in fondant with one of the layers having Chocolate BC under it. Is this going to cause a problem? My concern is that the chocolate will show through and throw off the look of the entire wedding cake. If I am not able to cover the entire cake with it, I will just fill it with Chocolate BC and cover it with regular BC.

it wont show through, as long as your fondant is not too thin. I use ganache under mine and that is quite dark and you cant see it

great! Thank you!!!

This past week I covered a chocolate cake with white fondant. I was worried about the same thing, but it was fine. Just make sure your BC is as smooth as can be since white fondant seems to show imperfections more. Good luck!!

thanks for the advice... that is another concern I have! I have been having fondant problems, so all I can do is pray that everything comes out nice!
