So I know kitchen cakes are suppose to look just like the wedding cake, so are you suppose to make a 2 sheets cakes (each 2" tall) and stack them to make one 4" high sheet cake with icing/filling in the middle? if so, do u charge the same? i always thought they were suppose to be cheaper? help would be awesome!

Yes, that's what they are... they match the wedding cake on the inside, but they aren't typically decorated (maybe just a border) and they aren't tiered cakes with supports so usually cost less.

so instead of making 1 sheet cake (2" high) and torting it, i actually make 2?
