I'm getting ready to make a cake consisting of several instruments and I would like to have a drum that is 9" round and about 6 or 8" high. I'm a bit concerned about stability so I'm wondering if I can use dummy layers on the bottom and then 4" of cake on top of that? Will I have a problem covering the the sides with fondant? Any advice or suggestions would be very much appreciated!

Dummy cake on the bottom......I would give the dummy cake a light crumb coat before placing the real cake (which should be on a board) on top...just to keep any loose strofoam pits from getting transferred to the real cake.... put in a couple of dowels thru all layers for stability.....crumb coat the cake as a hole....ice and decorate....

Thanks! That's exactly what I was thinking but it's nice to have confirmation that it will work!
