I'm going to be making the Orange Cake for a group of 40-50 soon, so will be making several cakes to feed the whole group. I'd like to make a thicker cake, so am considering doubling (or making 1 1/2 times) the recipe to make each cake thicker.
Has anyone tried this? Is it a straight doubling, or are any changes needed to make it work in a larger quantity?
I'm also debating the icing to use. The cake has such a wonderful, strong flavor that I don't want to cover it up with a powdered sugar icing. I'm vegan, so wouldn't be using any heavy cream to thicken the icing, so am looking for one that is thick enough to stay on the cake (and maybe even be decorated). Any suggestions would be most appreciated!
