1 small package instant pudding (any flavor)
1/4 cup confectioners sugar
1 cup cold milk (I use skim)
1 80z. container cool whip (thawed) - I used cool whip lite
Combine pudding mix, sugar, and milk in small bowl.  Beat slowly with
rotary beater until well blended, about 1 minute.  Fold in whipped
topping.  Spread on cake that is completely cooled.
