When did adding candles to a birthday cake originate?

As with the marketing of birthday cakes, the addition of candles is also attributed to the Germans around the 1700’s when Kinderfesten, birthday celebrations for children, became more common. The custom was to place a candle for each year of their life as well as extra candles to represent years to come.
