What each ingredient does

Coffee sugar: Provides the sweetness and the firm, chewy body that sets the caramel.
Butter: Adds fat for richness and a soft, smooth texture.
Cream: Adds moisture and helps the sugar dissolve into a smooth, soft mixture.
Baker's chocolate: Supplies the chocolate flavor and extra fat for a rich, smooth finish.
