I'd appreciate if you can give me an advise or two. I have to make a square wedding cake for my girlfriend in a couple of months. I've made 3-tier round birthday cakes in the past with using store bought cake boards (cardboard ones). Since the wedding cake will be at least 3-tiers and will be a lot bigger than the cakes I've made so far I don't know what I need to use for the bottom of each tier. The wedding cake will be at least 14"-16" bottom tier and will be either 3 or 4 tiers. Are these store bought cardboard cake bords strong enough to hold the weight? Or do I need to use something else? Please help!!
The boards don't have to be strong to hold the weight, it is the dowels that hold the weight. The bottom board should be the only strong board, (I use wood covered in fondant), all the other layers can just be on cake circles cut to size.
I have done several 4 tier square cakes. I use foam board under each tier and use bubble tea straws instead of dowels. I always stack on site.
