What each ingredient does
- Brown sugar
- Provides caramel sweetness and, as it cooks, the firm body of the frosting.
- Thin cream
- Adds moisture and dairy richness, helping the sugar dissolve and cook evenly.
- Butter
- Adds fat for a softer, smoother texture and a rounded dairy flavor.
The step that matters
Cook to the soft-ball stage. Sugar concentration sets the final firmness. Stopping too early leaves the frosting runny, while cooking too long makes it hard. Beating off the heat encourages small sugar crystals, giving a smooth, spreadable texture.
