The birthday cake is often decorated with small candles, secured with special holders or simply pressed down into the cake. The cake can also be served with other sweets such as ice cream. In the UK, North America and Australia, the number of candles is equal to the age of the individual whose birthday it is, sometimes with one extra for luck. Traditionally, the person whose birthday it is makes a wish, which is thought to come true if all the candles are extinguished in a single breath.
