I am making a cake to resemble an amplifier. It will be small, 12"L X 4"D X 6"H. Torted, filled, covered with fondant. To this point I have not made any cakes over 4" tall. Will I need some type of support? Cake board between layers?
I believe the "rule" is supports (cardboard circles/dowels or straws) for every 4 vertical inches.
I thouhgt I had read that at one time. So I suppose I could to 4 inches with bubble straws and then a cake board with the top tow inches on it?
A "kind" way to do it for cutting and serving is to create 2, 3 inch high layers and put supports in the bottom layer.
This makes it easier to cut, no one gets "short" pieces, and the pieces fit better on dessert plates.
