A cupcake is a small individual cake that is baked in a cup-shaped container, typically made from paper or aluminum. It consists of a light and fluffy cake base, often flavored with vanilla or chocolate, and can include various add-ins like fruits, nuts, or chocolate chips. Cupcakes are topped with frosting, which can be buttercream, cream cheese, or fondant, and decorated with sprinkles, edible glitter, or other embellishments. They are enjoyed as a sweet treat for birthdays, parties, and special occasions, and their single-serving size makes them convenient and popular for dessert or a small indulgence.
