Cream Cheese Frosting

4 ounces cream cheese, softened to room temperature
3 Tablespoons unsalted butter, softened to room temperature
1 teaspoon pure vanilla extract
1 1/4 cups confectioners' sugar
1 Tablespoon fresh lemon zest (optional)

Beat the cream cheese and butter together until smooth. Add the vanilla and continue mixing until well blended. Measure and sift the confectioners' sugar directly into the bowl and mix until smooth. Stir in the lemon zest, if desired. Spread on cool brownies, bars or cookies and refrigerate to set the frosting before cutting. Keep refrigerated until ready to serve.

Makes 1 cup.
