Crush graham crackers. This can be done in a food processor or blender, or even place the graham crackers in a bag and crush them with a rolling pin. After crushing the graham crackers, combine the crumbs, butter, and sugar and mix. Press into a 9x13-inch pan.
Mix the two packages of Dream Whip according to the package instructions. This is easiest to do with a kitchen aid mixer or hand-held mixer. Make sure to whip until it thickens and forms soft peaks. Move to a separate bowl to save for later.
Cream the cream cheese, sugar, and vanilla until smooth.
Combine Dream Whip and cream cheese mixture and fold together.
Fill the graham cracker crust with the mixture.
Place into the refrigerator to keep cool while making the fruit mixture.
In a saucepan, heat the frozen fruit over medium heat. Warm the fruit and use an immersion blender to blend the chunky fruit. (BE CAREFUL IF HOT!)
Bring the fruit to a boil.
Add the cornstarch (or jello), lemon juice, and sugar and whisk together.
Allow fruit mixture to cool and pour over cheesecake.
Chill dessert and serve cold. Enjoy!
