Of yes, have you ever think of what is the difference between a muffin and a cupcake?
If I were to choose, I prefer a muffin (any flavour) rather than those icy-colourful cupcakes. But, it doesn't mean I don't eat them at all. Kalau ada depan mata, of course I'll eat it =)
I've found this from this great site,
The quick-and-dirty answer on this is that cupcakes have frosting, whereas muffins do not. However, in researching, I found an excellent formulaic definition of the difference courtesy of Diana's Desserts: 'A basic formula for muffins is 2 cups flour, 2-4 tablespoons sugar, 2½ teaspoons baking powder, ½ teaspoon salt, 1 egg, ¼ cup oil, shortening or butter and 1 cup milk. When the fat, sugar and egg ratio in a recipe reaches double or more than this, you have reached the cake level.
As for me, I would say muffin's texture is very much airy and softer rather than cupcakes. And it normally uses vegetable oil instead of butter in cupcakes.
