Prepare the Crust: In a mixing bowl, combine the graham cracker crumbs and melted butter. Press the mixture into the bottom of a 9-inch pie dish to form the crust. Set aside.
Dissolve the Jello: In a separate bowl, dissolve the lemon jello in 1 cup of boiling water. Stir until completely combined, and set aside to cool slightly.
Mix the Cream Cheese: In another mixing bowl, beat the softened cream cheese and sugar until smooth and creamy.
Combine: Slowly add the cooled jello mixture to the cream cheese blend, mixing until well combined.
Fold in Cool Whip: Gently fold in the cool whip until everything is silky and evenly mixed.
Assemble: Pour the jello and cream cheese mixture over the graham cracker crust in your pie dish. Smooth the top with a spatula.
Chill: Refrigerate for at least 4 hours, or until set.
Serve: Slice and serve, garnishing with your favorite toppings!
