A cupcake is a single-serving cake that is typically baked in a small paper or aluminum cup. It is a delightful and portable treat that can be enjoyed by one person. Cupcakes come in a variety of flavors, including chocolate, vanilla, and red velvet, and can be topped with frosting, sprinkles, or other decorations. They are perfect for birthdays, parties, or as a sweet indulgence any time of the day.
