I have done a few fake cakes in the past and have put the layers together using dowel rods. I would stick one end in the bottom cake and one in the next one above it. But it is hard to estimate where to put the dowel. I find the cakes too light weight so I had to use something, otherwise transporting them was a nightmare. IS there a better way of doing this?
I stick them together with Royal Icing. That seems to work fine for me.
You put the royal icing over the fondant?
Yes, just a few dabs/dollaps of it to adhere it all together. Takes about 5 or 10min for it to stick together, but mine usually sit 30min or more cause I'm usually doing other stuff.
I use only BC on my dummies (never use royal for anything but cookies). I can pick up a 4-tier dummy cake by the top tier and it all holds together.
