Chocolate Sour Cream Icing

Introduction

Chocolate Sour Cream Icing uses melted chocolate chips, butter, and sour cream to make a frosting with a smooth texture and a slightly tangy finish. The double-boiler method keeps the chocolate from scorching, and the icing sugar lets you choose between a thinner icing and a thicker frosting. You can use it for a quick layer cake, a sheet cake, or cupcakes when you want a chocolate topping that comes together fast.

Recipe Details

• Prep Time: 10 minutes
• Cook Time: 8 minutes
• Total Time: 18 minutes
• Servings: 12

Ingredients

• 1 cup (240 g) chocolate chips
• ¼ cup (60 g) butter
• ½ cup (120 g) sour cream
• 1 tsp vanilla powder (use half this amount if you prefer less rich vanilla flavor)
• ¼ tsp salt
• 1-3 cup (240-700 g) icing sugar

Instructions

1. Melt the chocolate and butter together in a double boiler.
2. Remove mixture from the heat, then stir in the sour cream, vanilla powder (use half this amount if you prefer less rich vanilla flavor), and salt.
3. 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.
4. Spread mixture on the cake of your choice.

Variations

• Use dark chocolate chips instead of chocolate chips for a less sweet icing with a deeper chocolate flavor and a slightly firmer set.
• Use milk chocolate chips instead of chocolate chips for a sweeter, softer frosting that pairs well with plain vanilla or yellow cake.
• Replace the sour cream with full-fat Greek yogurt for a tangier icing with a slightly lighter texture.
• Change the final step by stopping earlier on the icing sugar for a pourable glaze, or beating in more for a thicker spreadable frosting.

Tips for Success

• Keep the double boiler at a gentle simmer so the chocolate chips melt smoothly instead of overheating.
• Let the melted chocolate and butter sit briefly off the heat before adding the sour cream to reduce the chance of splitting.
• Add the icing sugar gradually, because the texture changes quickly and thickens more as the icing cools.
• Spread the icing while it is still soft and workable; once fully cooled, it firms up and is harder to move cleanly.

Storage and Reheating

Store the icing in an airtight container in the fridge for up to 5 days. Press plastic wrap directly onto the surface if you want to limit drying.

Freeze it in a freezer-safe container for up to 2 months. Thaw it overnight in the fridge before using.

To reuse, let the icing come to room temperature and stir until smooth. If it is too firm to spread, microwave it in 5-second bursts or set the bowl over barely warm water until loosened.

FAQ

Can you use this as a glaze instead of a frosting?

Yes. Stop adding the icing sugar sooner and spread or pour it while the mixture is still warm.

Why did the icing turn grainy?

The chocolate usually got too hot, or the sour cream was added when the chocolate was still very hot. Use gentle heat and let the melted mixture cool slightly before stirring in the dairy.

Do you need a double boiler for this recipe?

You need gentle indirect heat, but it does not have to be a dedicated double boiler. A heatproof bowl set over a pot of simmering water works the same way.

Can you replace the sour cream?

Yes, full-fat Greek yogurt is the closest substitute. The icing will be a little tangier and slightly less rich.
