Question: muffins are better than cupcakes?
Answer: Cupcakes are a lot lighter than muffins when it comes to the bread base, but just the bread. The lightness is a result of the way butter gets creamed with sugar, and the cupcake batter is beaten for a longer time than that of a muffin to achieve a fluffier texture. The frosting added gives it a bit of top-heavy heft.
