  Amount  Measure       Ingredient -- Preparation Method
--------  ------------  --------------------------------
12        ounces        cream cheese
12        tablespoons   unsalted butter
1 1/2     teaspoons     vanilla
6         cups          powdered sugar, sifted
                        Grated lemon or orange zest, ground cinnamon, or liqueur of choice

Preparation:

Have the cream cheese cold and the butter at room temperature. In a medium bowl, beat cream cheese, butter, and vanilla until blended. Add sugar one-third at a time and beat just until smooth and the desired consistency. If frosting is too stiff, beat for few seconds longer. Do not overbeat. If desired, stir in additional flavoring to taste.
