Chocolate sour-cream icing is an icing or frosting with a bit of tang to take the edge off the sugar overload. It can be icing or frosting depending on what you want.
Time and difficulty are editorial estimates; allow extra time for your equipment and experience.
Tap an ingredient as you get it ready.
Melt the chocolate and butter together in a double boiler.
Remove mixture from the heat, then stir in the sour cream, vanilla extract, and salt.
Slowly beat or stir in the icing sugar until the mixture has the desired consistency. An icing will be thinner and require less icing sugar than a thicker frosting.
Spread mixture on the cake of your choice.
