1. Combine the whip cream, cream cheese, sweetened condensed milk, lemon juice, and vanilla extract in a large bowl. Mix on high speed until SMOOTH. Taste and add more lemon juice to your liking.
2. Pour into crust and refrigerate overnight.
3. NOTE: Keebler is the only brand I have seen that serves the large graham cracker crust. It will have the note '2 extra servings' on the label.
4. NOTE: If you do not have enough time to let the cream cheese get to room temperature, I sometimes will microwave it 10 seconds at a time until it is fairly soft.
