Sour Cream Frosting

Sour cream frosting is the obvious choice for sour cream cupcakes. This sour cream frosting is based on a basic vanilla bean buttercream frosting. However, instead of using milk in the frosting, the sour cream frosting uses sour cream.

Even if you are not a fan of sour cream, you still may enioy the sour cream frosting. The sour cream flavor is subtle. It adds a pleasant tang which helps to counteract the sweetness of the buttercream. Try it and let me know what you think!

Sour Cream Frosting

Sour Cream Frosting


  • 1 1/2 C confectioners' sugar (add more until it reaches your preferred consistency)

  • 2 T sour cream


  1. Mix together sugar and butter until they are blended and creamy.
  2. Add vanilla bean paste and sour cream and continue to beat for another minute.
  3. If desired, add more vanilla bean paste to taste, or more confectioners' sugar to make it stiffer.

    My friend’s dad makes the most AWESOME chocolate cake with chocolate sour cream frosting. He makes it whenever we go there for dinner. I haven’t had vanilla sour cream frosting though. Definitely need to give this one a try.

    Could I substitute vanilla yogurt for the sour cream?
