Chocolate Frosting

Ingredients

Directions

Make the frosting

  1. In a saucepan, combine sugar, cream, scraped chocolate, salt, and cinnamon bark if using.

  2. Cook without stirring until the mixture can form a fine thread when tested.

  3. Remove from heat and let cool.

Beat and finish

  1. Once cool, beat the mixture until it reaches a thick cream consistency.

  2. If you did not use cinnamon, add vanilla extract for flavor.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Granulated sugar
Provides sweetness and, as it cooks, the syrup that sets into a firm, smooth frosting.
Cream
Adds moisture and fat, giving the frosting a smooth, creamy texture.
Chocolate
Provides the chocolate flavor and fat that help the frosting set and thicken.

The step that matters

Cook without stirring until a fine thread forms. Stirring during cooking can trigger sugar crystallization, making the frosting grainy. The thread test shows the sugar has reached the concentration needed for a smooth, thick set after cooling and beating.
