What are the similarities of a butter cake and a sponge cake?

Does caster sugar help make sponge cakes fluffier?
The higher the proportion of sugar in a cake, the lighter it will be (up to a point). However, the downside is that as the proportion of sugar increases, so does the stickiness of the crumb, and as the crumb gets stickier, the cake will be inclined to rise less.
Using caster sugar instead of granulated sugar will result in a comparatively fluffier cake.

you probably wont, so i would suggest finding just a normal sponge cake recipe, get a calculator if you're no good at math, and then just work out how much of the other ingredients you would need if you use 24 eggs (it would probably be 12 times everything, wouldn't it??)
