These kits are a wonderful idea for children.
Place the cupcake liners in a baking tray.
Pour the cake mixture into a bowl,
then add one medium egg and two tablespoons of water. Mix well.
Spoon the mixture into the cupcake liners.
Not much is needed in each as the mixture does rise.
Bake for 12-15 minutes on Gas Mark 7.
Whilst waiting, add some water to the coloured icing mix to the consistency you like.
Once the cupcakes are cool, add the icing and edible decorations.
