I found this elsewhere

+The original recipe calls for:

°1 can of condensed milk
°1 jar of Cool Whip.
°1 package of koolaid.
°I believe the jello mix would work well too
°I would imagine something like this because that's how I make my cheesecake:
°Graham cracker crust
°1 jar of Cool Whip
°1 packet of cream cheese
°1 cup of sugar
°1 packet of kool-aid

If you just want a plain cheesecake, then instead of a packet of koolaid, make a teaspoon of vanilla.
Combine ingredients and pour into crust. Cool in the refrigerator. 

Enjoy !
