2 x 8 ounce packages cream cheese, cut into cubes, cold  

2 lbs (about 7 1/4 cups icing sugar (confectioners)  

2 teaspoons pure vanilla extract  

Method:  

Using electric mixer, combine butter and icing sugar until just combined. Add cold cream cheese, all at once, and beat on medium speed for about 4 minutes. Turn up to high speed for another 1 minute. Should be fluffy. Don't overbeat, or the icing will start to lose thickness.
