Using the whisk beater of your mixer, cream together the butter and cream cheese.
Beat in the vanilla bean scrapings and salt.
Add the sugar, one cup at a time, beating very very well after each addition. [start out at a low speed each time to prevent the sugar ending up all over the place]
Add the cream, one tablespoon at a time, until it is of spreadable consistency. Beat another minute or so for maximum fluffiness.
Can be used right away, but if allowed to sit at room temperature for a couple hours, the vanilla flavor will become more pronounced.
Should be stored refrigerated.
Notes
Will frost about 4 dozen sugar cookies, or a 2 layer cake
