I have always done two layer tiers and only have seen and figured up serving sizes for two. I would like to make a three layer tier since I love how tall they look. Is there a place that gives serving sizes for that or can someone tell me how many serving to add on for an extra layer. Thanks so much!
A 10" round, 2-layer cake serves 38 per the wilton wedding chart.
A 10" round, 3-layer cake serves 38 except the pieces will be taller. The surface area is the same, so you get the same number of cuts.
Since they are getting 50% more cake, you should be charging 50% more per serving ($3/serving is the regular price for a 2-layer cake .... so it should be $4.50/serving for a 3 layer cake).
Totally agree w/Indy
