Adding just a touch of sour cream into frosting can make a world of difference!

Tips for Making Sour Cream Icing

You can take a few steps to make sure that your sour cream frosting recipe comes out great every time:

  • Make sure that all ingredients are at room temperature. The butter needs to be soft but not melting, and the sour cream should have been sitting out of the refrigerator for a few hours before you begin.
Adding sour cream to frosting
Sour cream icing will have a similar consistency to a classic buttercream but with a slightly tangy flavor that adds interest to your favorite baked goods!
  • Beat the butter on high speed with an electric mixer for three minutes. Beating the butter this long is necessary to incorporate air; if you beat it for too short of a time, the frosting will be heavy instead of light and airy.
  • You can use vanilla extract, but try using vanilla bean paste for a stronger vanilla flavor. It’s made with actual vanilla beans and the flavor is sensational.

Best Ways to Use Sour Cream Icing

  • Lemon Cupcakes (Use instead of lemon frosting with lemon cupcakes if you don’t want too intense of a lemon flavor.)
  • Cherry cupcakes (You’ve heard of sour cherries, but sour cream paired with cherries is just as good!)
  • Banana cupcakes (Bananas go really well with the tart flavor of sour cream.)
  • Vanilla cake (This sour cream frosting goes perfectly with any vanilla cake recipe.)
  • NY Cheesecake (Pipe the frosting on top of cheesecake instead of whipped cream to make it even more decadent!)

Use full-fat sour cream for the richest frosting flavor. However, low-fat sour cream and even Greek yogurt will also work.

You can also use cream cheese and it will be great – but I like to use a higher ratio of cream cheese to butter than I do sour cream to butter. See my cream cheese frosting recipe for the exact recipe.
