How to Make It
With an electric mixer on medium, beat the cream cheese until softened. Slowly add the sugar, zest, and juice and beat until creamy, about 3 minutes.
Tip: For lump-free frosting, you will need room-temperature cream cheese. To hurry the process up, place an unwrapped block of cream cheese on a plate and microwave it at 50 percent power for 10-second intervals.
