How do I calculate servings for a topsy turvy cake? TIA
I've never done a topsy turvy but i have a thought. Keep track of the amount of batter you use. Compare that amount with the serving chart you use for regular pans. That should give you a good idea of how much cake there is.
What we would do (and we've only made one) is calculate 1/4 more servings and charge for 1/2 as much more. For instance, a 6" round serves 12. We would say it could serve 15 and we would charge them for 18. The reason being is that the top portion is going to be almost a full layer higher than the whole cake but the lower end will make the slice about as big as if you didn't put the topsy on it. However, the reason for charging for 18 is because you still have to make a whole layer of cake.
HTH....Email if you need more help.
