In layer cakes, you want the top to be even but in cupcake it's much more pleasing to the eye to have the top round and puffy (at least to me).
So I tried filling the muffin cups more than 2/3 full, in fact I think I went 4/5 full. All that did was make them over flow :P
I see the ones in supermarket to be puffy, yet the ones from Citizen Cake does not.
How does one achieve puffiness without sacrificing taste?
