This cak e is iced smooth with buttercream. Chocolate MMF loop bow and ribbon. I have been having problems with my buttercream that has butter and Crisco in it, so I added cornstarch to the recipe. It helped a lot, but I am still getting hairline cracks that appear on the sides of the cake. I posted the recipe on the thread entitled...Answer to the New Crisco Problems - New Recipe. Any help would be great!
