What each ingredient does

Butter
Adds richness and a smooth, creamy body to the frosting.
Icing sugar
Sweetens the frosting and thickens it as it is beaten into the butter.
Coffee essence
Gives the frosting its coffee flavour.

The step that matters

Spread over the cake using a knife dipped in warm water. Warm water slightly softens the frosting's surface so the knife glides smoothly without dragging or tearing the layer, giving an even finish.
