Add the softened butter and cream cheese to the mixing bowl and beat until light and fluffy, followed by the vanilla extract.
Add the powdered sugar and beat until smooth and thick.
Drizzle the heavy cream into the cream cheese frosting mixture while beating to create a spreadable consistency.
Add the frosting to a piping bag and snip the corner off to decorate cakes and cupcakes. You could also use a decorator’s bag with a star-shaped tip.
