If you put icing on a muffin would that make it cupcake?

Putting frosting on a muffin does not make it a cupcake. Cupcakes are a type of sweet cake that is typically made from a wet batter and then baked in individual cups or molds. Muffins, on the other hand, are a type of quick bread that is made from a dry batter and can be baked in a muffin tin, bread loaf, or even in a coffee mug.

While both cupcakes and muffins are often topped with frosting or icing, the main difference between the two lies in their batters. Cupcake batter is typically made with a creaming method, which involves creaming together butter and sugar until light and fluffy, before adding the eggs, flour, and other ingredients. Muffin batter, on the other hand, is usually made with a mixing method, which involves simply mixing together all of the ingredients until just combined.

In terms of texture, cupcakes are generally lighter and airier than muffins due to the creaming method and the incorporation of air during the mixing process. Muffins, on the other hand, tend to be denser and more moist due to the use of a mixing method and the presence of less air in the batter.

Lastly, cupcakes are often more elaborately decorated than muffins. They may be topped with various types of frosting, sprinkles, candies, or other decorations, while muffins are often left plain or topped with a simple streusel or crumb topping.
