Cool to room temperature.

For frosting, beat together the cream cheese, butter, and 2 teaspoons vanilla until light and fluffy. Gradually add 2 cups sifted powdered sugar and cocoa powder, beating well. Gradually beat in remaining powdered sugar until smooth. Beat in milk if needed, to reach spreading consistency.
