Hello friends! I just love the fact that there is ap lace that we all can come to to task our questions and to help other people out. Anyway.... I am doing another wedding cake but this time the customer wants chocolate fondant. I have never made it before. Do I just replace some of my powdered sugar and use cocoa powder? Also... does anyone have a ratio for how many ounces of rolled fondant it takes to cover a cake (be it any inches). Thank you!
