I would like to make a robot cake for my son's birthday and was originally planning to just stack square cakes for the body but, after thinking about it, thought the body would look better if I put three square cakes together and then stack on end (tall rather than flat). I have never tried this and was wondering if anyone has and how to secure these cakes so that they do not separate or fall apart at the party. I am planning to cover the whole thing with fondant but not sure if this is enough to keep it together. Also, I will then be stacking the robot's head on top of these cakes which will be smaller square cakes. Help...party is this Sunday!!

I wouldn't do it... gravity will win.

You're better off cutting your square cakes and stacking the portions removed to build up the shape you want.

Yep , ditto that reply.

and dowels!!!! That will help.

agree with the above posters.

Yes, I have to say that I would not even attempt that. I'm guessing the cakes will just collapse no matter what you do. Go with the regular way of stacking cakes.

I would go there...sounds like a cake disaster waiting to happen! Just cut your squares to the size you want and stack normally with board and dowel support for every 4" in height.

I did a R2D2 for my son last year. I took 8" rounds and stacked like normal covering the whole thing in fondant. For the head I used the sports ball pan. Every 4" had a SPS plate. It was at least 12" tall. I would definitely use support or it will be a disaster!
