Start by measuring out all of your ingredients so everything is ready to go.
In a glass mixing bowl, beat together the softened cream cheese, butter at room temperature, sour cream, and vanilla extract using a hand mixer until the mixture becomes light and fluffy.
Gradually add the powdered sugar in thirds, mixing well after each addition to keep the texture smooth.
Once all the sugar is fully incorporated and the frosting looks smooth and creamy, it is ready to use.To decorate: Use a cake spatula, silicone spatula, or piping bag to apply the frosting.To pipe the frosting: Spoon it into a pastry bag fitted with a metal tip, twist the top, and trim any extra bag length before piping.
