What each ingredient does
- Icing sugar
- Provides sweetness and bulk, dissolving to form a smooth, pourable icing.
- Cocoa powder
- Supplies the chocolate flavour and deep colour of the icing.
The step that matters
Pour the icing while warm. Warm icing stays fluid and spreads smoothly over the cake. As it cools it thickens and sets, so pouring after it cools can leave it lumpy or too stiff to coat evenly.
