What's the difference between a cupcake and a muffin in terms of their ingredients and preparation?

The main difference between a cupcake and a muffin is that cupcakes are typically sweeter and richer, with more sugar and butter in the batter. Cupcakes are also usually topped with frosting. Muffins, on the other hand, are less sweet and often include ingredients like fruits, nuts, or oats. Muffins are usually mixed using the "muffin method," where wet and dry ingredients are mixed separately and then combined.
