1 pack instant pudding (your choice of flavor)
1/4 c. confectioners' sugar
1 c. very cold milk
1 (8 oz.) container Cool Whip

Combine pudding mix, sugar and milk in small bowl. Beat slowly at lowest speed about 1 minute until blended. Fold in Cool Whip. Spread on cooled cake. Store frosted cake in refrigerator. For best results always chill beaters before blending.
