In a large bowl, whip the butter until creamy. Add in the vanilla extract and then mix again until well incorporated.
Alternate between additions of powdered sugar and whipping cream, mixing well between each addition.
Once all the sugar is added, turn mixer to high and beat for several minutes until the frosting is fluffy and smooth. Add more whipping cream 1 tsp at a time as needed until at desired consistency
Use frosting immediately or cover the bowl with a damp paper power until ready to bag or spread.
