HI

I am quite and experinced cake decorator, but have little experience in wedding cakes,
I have a 3 teir cake coming up that will be stacked, 13,11" in sponge and a 9" fruit on teh top,

my question is ..... will the sponge support the fruit cake and if not what should i do to support it?
Hope you can help thanks Jo x

As in most tiered cakes, you need a dowling support system.

Cakes don't support the weight of other cakes in stacked or tiered configurations - that's the job of the various & different styles of cake support systems.

Here's a pretty comprehensive thread on baking, assembling and decorating your first tiered/stacked/layer cake:

You would be most interested in the cake assembly portion (how to stack/tier) which has links to illustrated and fully detailed instructions on numerous common cake support systems.

Additionally, Leahs extensive info on the SPS system is also there.
