Has anyone ever used 1/2 inch foam core for a three tier cake? 12", 9" and 6" tiers? I am trying to avoid the weight of wood, but I will use it if there is any chance the foamcore isn't strong enough.

I have used it for a three tier cake but I stacked two pieces together just in case. I taped them together along the edges with masking tape and then covered it with freezer paper. It seemed pretty sturdy. It had to be carried from my parents house to the car and then down into a church basement. I can't imagine how heavy it would have been had it been wood!

You will be fine! I have stacked 4 tier cakes on the thicker foamcore and it traveled over an hour with no problem.

Really for that size I have used the silver cake drums that wilton sells since it's not very heavy. HTH!

Why not try a mirror. That is thin light weight and you can cover it with whatever, food approved paper or fancy foil or even fondant. Trim with a nice ribbon and you are good to go. I got a round mirror at Michaels for a few dollars. Best of all wash and reuse.

Thankyou for the replies. I forgot to mention that this cake will be square. Otherwise I would have used the drums, as they seem very sturdy.

Try Masonite it's sturdy and light.
