Cupcake batter is a mixture used to make cupcakes, a popular baked treat. It typically consists of flour, sugar, eggs, butter, milk, and baking powder. These ingredients are combined to create a smooth, thick mixture that can be flavored with vanilla, chocolate, or other ingredients. Once the batter is prepared, it is poured into cupcake liners placed in a muffin tin. The batter rises and bakes in the oven, transforming into fluffy, sweet cupcakes. After baking, they can be decorated with frosting, sprinkles, or other toppings to enhance their appearance and flavor.
