When my daughter was one (many moons ago), I bought a swiss roll, spread a little jam over it, so icing would stick. Made fondant icing and iced the whole thing. I then stood it up, stuck a matchmaker down the centre and shaped a flame out of marzipan. A tiny amount of red food colouring made the flame look authentic and a few drips of royal icing placed strategically to look like wax. Voila.....a candle!!
You can buy the swiss roll and the now ready made icing in any Tesco or Superquinn. Will literally take you 10 minutes.
