I am curious to see what everyone else does. I use the 2" cake pans and normally only torte between the two cakes when making my tiers. So it turns out to be about 4" per tier. I noticed some do more than one torte, and I was just curious to see what everyone does? I definately like the look of more than one torte.
I cut each 2" layer in half so I end up with 4 layers, just under an 1" a piece. I use 3 layers of filling, but the entire cake only comes to 4" high when I'm finished. If I make it any higher I can't fit them in the cake boxes (party cakes). Sheet cakes I only cut in half for two 1 1/2 inch layers (total 3 inches).
I use 2" pans and I cut each in half using a thin layer of filling in between also. For a total of 4 layers cake three layers of filling. I prefer this because it makes for a pretty slice and you get a bite of filling with each bite of cake.
