1 c. cold milk
1 (4 oz.) pkg. Jello instant pudding, any flavor
1 (8 oz.) container Cool Whip, thawed

Pour milk into bowl. Add pudding. Mix with mixer, about 2 minutes. Blend in Cool Whip. Frost cake, cupcakes, etc. Keep refrigerated. My family loves this frosting. It's not real sweet. (You can also add 1/4 cup of powdered sugar after pudding mixture.)
