I am making a birthday cake for 80 people for this Saturday. I have a question regarding the size of the cake. The cake that the client wants is a two tier cake in a topsy turvy style. The cake she wants is not really slanted, it's just stacked normally but shaved down on the sides. My question is, what size pans do I need in order to make this cake work for that amount of people. Would a 12 inch and a 10 inch be enough, considering I am shaving down the sides?
Here is a picture of the cake she wants (InspiredbyMichelle Blog)
Here's a great little tool for calculating how much cake you need, posted on Cake Central some time ago by metria, from Austin, TX:
According to this table, a 10" round cake (which is 4" high, the industry standard) will give you 28 portions, a 12" will give you 40 and a 14" cake will give you 63. You might want to try a 10" and a 14", which should be about right for two reasons: first of all, you need to make more than 80 servings because you're going to carve the rounds down slightly to get the topsy-turvy effect and, second, because a difference in diameter of 4" between tiers looks better than a 2" difference (IMHO!). HTH!
