In a large mixing bowl, beat the unsalted butter using an electric mixer on medium speed until smooth and creamy, about 2 minutes.
Gradually sift in the powdered sugar, about 1/3 at a time, mixing on low speed after each addition. This helps prevent powdered sugar from puffing out of the bowl.
Once all the powdered sugar is incorporated, increase the mixer speed to medium and beat for another 2 minutes until fluffy.
Add the sour cream, vanilla extract, and a pinch of salt to the mixture. Continue beating on medium speed until fully combined and the icing is smooth and creamy, about 1-2 minutes.
Taste the icing and adjust as desired. For a slightly tangier flavor, add an additional 1-2 tablespoons of sour cream; for sweeter icing, sift in more powdered sugar as needed.
Use immediately to frost cakes, cupcakes, or other baked goods. Alternatively, store in an airtight container in the refrigerator for up to 3 days. Allow the icing to come to room temperature and stir before using.
