Sour cream frosting adds a delicious tangy note to the classic sweetness of buttercream frosting. This sour cream frosting won’t taste like sour cream, but people will notice its wonderful bright flavor when paired with all manner of cakes and cupcakes.

Tips for Making Sour Cream Frosting

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

  • 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 Frosting

  • 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!)

Substitutions

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.
