I have a 3 tier cake due tomorrow. The top two are dummy cakes 6" and 8" covered in fondant. The bottom tier is the actual cake which is 12" also covered in fondant.
Since fondant is typically heavy, i figured that I will need some support, so that the bottom layer will not be crushed. What do you suggest I use? Do I use dowels in the bottom layer only? Or will I have to go through all three layers?
Also, can I use plastic, or are the wooden ones better? Sorry for asking so many questions about this..... just want to prevent a disaster!
You won't need any supports, they won't be that heavy unles you've putthe fondant on 1" thick. If you're really worried about it just put a few wooden dowels in the real cake.
I'd say the same, I've made cakes with dummy cakes on top and I just sit them on with a dab of royal icing to keep them in place.
For safety's sake, I'd definitely put in at least 4 dowels in the bottom tier to support that set of 2 dummies.
The dummies are very lightweight, but with fondant and decoration, I'd think that they could easily wind up weighing about the same as another tier of real cake--which you would definitely support with dowels in the bottom cake.
