What each ingredient does
- Icing sugar
- Provides the sweetness and body that thickens the icing as it sets.
- Cocoa powder
- Provides the chocolate flavor and dark color.
The step that matters
Pour the icing over the cake while warm. Warm icing flows smoothly and spreads evenly. As it cools it thickens, so if it cools too far it may become hard to spread and set unevenly.
