Will a 1/2 inch foam Core base be strong enough for a 2-Layered 3 Tier Cake, or should I double it, or use something else? The cake is Cake Mix with extender and the tiers are 6", 10", & 14". Thanks
I have a 13" double layer sitting on a 1/2" thick foamcore right now, and it held the weight very well. The layers that will go on top are 9" and 5". I will be assembling it at the reception site. If you want to pre-assemble then transport, I'd double the board because of the added weight.
If you're not going to assemble on site, I would use wood or masonite. A three tier cake is very heavy and I'm not sure I would trust the foam. I've never tried it so this is just my opinion.
I wouldn't trust one layer of 1/2 inch foamcore for that size cake. What I like to do is glue a same-size piece of masonite under the foamcore and cover the whole thing as one board. The masonite adds stability and the foamcore provides an anchor for the center dowel.
Man Diane, you are a genius, I always learn something new when you post!
