Sour Cream Buttercream

Sour Cream Buttercream


  • 2 sticks unsalted butter, softened
  • ½ cup sour cream
  • 2 teaspoons pure vanilla extract
  • 6 cups confectioners’ sugar, sifted if lumpy
  • 1-2 tablespoons of milk if needed to thin frosting


  • In the bowl of an electric mixer, using the paddle attachment, cream the butter, sour cream, and vanilla on medium speed until well blended.
  • On low speed, slowly add confectioners’ sugar and blend well. Scrape down sides of the bowl as needed with a rubber spatula.
  • If the frosting is too thick, add 1 tablespoon of milk if needed, and up to 2 to your desired consistency.


Makes enough to frost a 3 layer, 9-inch cake
