Mine are all different. I do find my dense ones are the ones I usually term as southern. Carrot, pumpkin, red velvet, hummingbird, banana. But these are also dense cakes. That strawberrry cake I have been giving out with changes on another thread is dense because of the moisture. But none of these are as dense as pound cake, just heavier.
Lighter are chocolate, vanilla, Key lime, lemon, coconut.
Maybe you like heavier cupcakes. I do. If I had to give ratios, I think my sales are 50/50. I think it depends on flavor and not too light or too dense.
I cannot convert my beaten egg white cakes into cupcakes. They are too light.
