Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Brown sugar
- Provides the sweetness and the caramel flavour of the frosting.
- Butter
- Adds fat for richness and a smooth, creamy mouthfeel.
- Powdered sugar
- Sweetens and thickens the frosting so it holds a spreadable body.
- Milk
- Adds liquid that loosens the mixture and controls how thick it gets.
The step that matters
Cool to room temperature before adding the powdered sugar. Warm caramel melts the powdered sugar and turns the frosting thin and greasy. Cooling it first lets the sugar blend in and thicken into a smooth, spreadable texture.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
