I am doing a wedding cake and the bride just changed her mind and wants a cake and cupcake combo. She wants the bottom tier to be a large square cake and then 3 tiers of cupcakes on square separators and then another square cake on top of that. I get how to make the square cupcake tower, but how do I start with the bottom tier as cake? If anyone has any ideas, or knows of any pictures on cc with this already done please let me know! I have 3 weeks left, she is a good friend and I could not tell her no with out doing some investigating first.[/b]

I've never seen it done before and to be honest I don't think it would look right. You're going to have to set it up with separator plates and the tall pillars, but I don't know if they'd hold hold up without the cake to grab into on the 3 center tiers, which would just hold cupcakes. You'd also have to disassemble the entire thing to cut the bottom square cake. I don't know if that set up would even work.

Well she really wants a cupcake tower, but wants a cake on the bottom so they can still cut the cake for the cake cutting part and pictures.

Why wouldn't just the cutting cake on the top tier work for that?
