Preparing Lemon Lush can be a seamless process if you follow these simple steps:

1. Preheat the Oven: Begin by preheating your oven to 350°F (175°C).
2. Prepare the Crust: In a bowl, mix the flour, powdered sugar, and melted butter until crumbly. Press the mixture into the bottom of a 9×13 inch baking dish.
3. Bake the Crust: Place the dish in the preheated oven and bake for about 15 minutes or until lightly golden. Let it cool completely.
4. Make the Cream Cheese Layer: In a mixing bowl, combine the softened cream cheese and granulated sugar. Beat until smooth and fluffy, then fold in 1 cup of whipped topping.
5. Spread Cream Cheese Mixture: Once the crust has cooled, spread the cream cheese mixture evenly over the crust.
6. Prepare Lemon Pudding: In another bowl, whisk together the instant lemon pudding mix and cold milk until thickened.
7. Layer the Lemon Pudding: Pour the lemon pudding over the cream cheese layer, spreading it evenly to avoid mixing.
8. Top with Whipped Topping: Spread the remaining whipped topping over the lemon pudding layer.
9. Chill: Cover the dessert with plastic wrap and refrigerate for at least 4 hours, or overnight for best flavor.
10. Garnish and Serve: Once chilled, you may choose to sprinkle lemon zest on top for an added touch before serving.

Each step is crafted to ensure that you produce a luscious, lemony delight that everyone will appreciate!
