I met with a bride and groom recently and they want the top tier of their 3 tier wedding cake as fruit cake with marzipan. Middle tier - WASC and bottom tier Chocolate. Has anyone every successfully put a fruit cake as the wedding cake top tier? Cake sizes - 8",10" & 12". I am concerned about the weight of a fruit cake on top of these cakes. Any challenges you encountered doing this?
My own wedding cake had a fruit cake for a top tier, lemon for the next, and chocolate for the bottom. There's no reason you can't do this. It's not the lower tiers of cake that supportthe tiers above, but the support system you use.
Use a good support sysgtem and you should be fine.
I would like to suggest (if possible) that you bake the fruitcake 7" diameter and 2.5"-3" deep. Because you will be adding two layers to it, marzipan and fondant. It will look "right" as the top tier.
Underneath, you need to use a generous number of dowels/straws for support. That plus a rigid cake board under the top tier will spread the weight around properly.
I have tiered three fruitcakes one on top of the other and they were 8-10-12" squares baked 3" deep. No problems.
Thank you all for taking the time to help me with this. I feel better now knowing this has been done successfully before
