A birthday cake is a special dessert traditionally served at birthday celebrations. It is often decorated with frosting, candles, and sometimes a personalized message. The cake can come in various flavors, such as chocolate, vanilla, or red velvet, and is typically layered to create a more festive appearance. During the celebration, the birthday person makes a wish and blows out the candles, symbolizing the passage of another year. Birthday cakes can be homemade or purchased from bakeries, and they often play a central role in the festivities, bringing friends and family together to celebrate the occasion.
