  2. Cool the mixture until it is warm to the touch, then beat in the vanilla.

  3. If the icing is too stiff, add a little more cream.

What each ingredient does

Brown sugar
Provides sweetness and caramel flavour, and sets the icing's body as it cools.
Sweet cream
Adds moisture and softness, loosening the icing so it spreads smoothly.
Butter
Adds fat for richness and a smooth, creamy texture in the finished icing.

The step that matters

Cool before beating in the vanilla. Beating the icing while it is still too hot can make it grainy or cause it to set unevenly. Letting it cool until warm to the touch lets the sugar crystals form a smooth, creamy texture.
