Sour Cream Frosting

Sour Cream Frosting is a creamy spreadable topping for cakes, cupcakes and cookies! Sour cream adds tangy flavor and a velvety texture to this sweet vanilla frosting recipe.


  • ½ cup unsalted butter, softened
  • 1 Tablespoon vanilla extract
  • ¾ cup full fat sour cream
  • 4 cups powdered sugar
  • ⅛ teaspoon kosher salt


  1. In a large mixing bowl, beat butter for 2 minutes. Add in vanilla and sour cream, beat an additional minute.
  2. Add powdered sugar and salt. Beat just until combined on low, then turn mixer to high and beat an additional 3-5 minutes, scraping down the sides of the bowl as needed. Frosting will be smooth.


  • If you want a thicker frosting to pipe on a cupcake, reduce sour cream to ½ cup.
  • Recipe makes enough frosting to frost 24 cupcakes or a double layer cake.
