A quick and simple icing that is great if you want a thin layer of icing that's easy to apply to your cakes, this type of icing is also good for lemon drizzle cake but instead of water you use lemon juice!
125g Icing sugar
15ml warm water
Heat up the water until warm, not hot.
Put the icing sugar into a small or medium bowl and add water.
Mix together until the icing becomes thick enough to coat with a back of a spoon.
If necessary, add more water (a drop at a time) until it is thick/ thin enough to use.
