i can pretty much calculate servings on anything but how in the world do you figure up the servings for a doll cake? I'll be using the wilton wondermold set.

Wilton says the wondermold serves 12.

As a rule of thumb, I figure 3-4 servings per cup of batter. For this type of cake, I'd probably use the 3 servings per cup, just because people will have more trouble cutting it than a square cake.
