A birthday cake is a cake eaten as part of a birthday celebration. While there is no standard for birthday cakes, they are typically highly decorated layer cakes covered in frosting, often featuring birthday wishes and the celebrant's name. In many cultures, it is also customary to serve the birthday cake with small lit candles on top, especially in the case of a child's birthday. The cake often accompanies the singing of "Happy Birthday to You". Variations include cupcakes, cake pops, pastries, and tarts.
