I have gotten myself into a pickle as I said that I would make a cake that resembles a slot machine. My question is-should I use some sort of filler or icing inbetween the layers or should I just stack all the layers together and do the carving and fondant? Any suggestions anyone might have would geatly be appreciated. Thanks Nan
I would fill, thinner than if it was just a regular 4" cake. You should use supports and boards every 4-6" of cake.
If you don't fill, some of the middle pieces won't have any frosting on them when served.
I did a slot machine cake a while back (in my photos) and it was about 10 inches tall and served 20..
All the cakes were torted, rough cut, filled, and stacked with dowels/cardboard support halfway through (after 5 inches). I generally make sure to support every 4-6 inches.
Here's a post about carving cakes: I posted some helpful tips on the last page.
