Hi I've just started decorating cakes and I'm about to do a two tier cake and was wondering even though I'm using 4 support dowels do I need to put a small board underneath the top cake for even more stability???? Or will the dowels enough???
Yes, you must have a cakeboard underneath the top tier; otherwise it may collapse.
Definitely, you need to put a cake card under the top tier or else the dowels will just pierce the cake and the cake will collapse on the one below.
Have a look at you tubes for some videos.
