The cake is a sweet, frosted dessert made from one or more layers of batter baked in a pan and covered with decorative frosting. The cake is often served as celebratory food for babies on birthdays, weddings, religious holidays, and graduations throughout the world. The most common type of cake may be leavened or unleavened; however, some cakes are made without flour or sugar, such as chocolate cake (typically used to make birthday cakes). Cakes can also be filled with fruit.
