Welcome to the Cake Decorators Q&A

I have to make a 12″ round sponge cake and have a 12″x3″ tin, if I make two (which makes the cake 6 ” deep, or deeper depending on the icing in the middle) how do I know how much fondant to use to cover the cake?. Would you recommend just baking one 12″ cake and splitting it?

Hi annescakes1

For a 12” round cake split into 3 and filled I usually allow 2k of sugar paste with some left over. There’s nothing worse than running short in the middle of decorating. If you intend stacking 2 lots of 12” cakes you will need to dowel the bottom cake and place the top one on it’s own card before stacking. Have a look at the vintage pearl cake tutorial where Paul decorates a double barrel cake. Look in the ingredients list for guidance on the quantity
of sugar paste he used. Bear in mind that he used the Carmass Massa fondant which he says is better for tall cakes as it doesn’t tear. If you make 1 cake and split it into 3, with filling,it will still make for a good height. I’m sure other members will contribute comment.
