Creating these Pistachio Lush Dessert Bars is a straightforward process. Follow these steps to achieve perfect results:

1. Prepare the Crust: In a medium bowl, mix the melted butter and graham cracker crumbs until well combined. Press the mixture firmly into the bottom of a greased 9×13-inch baking dish to form a crust.

2. Make the Cream Cheese Layer: In another bowl, beat the softened cream cheese and 1 cup of powdered sugar until smooth and creamy. Fold in 1 cup of whipped topping.

3. Spread the Cream Cheese Mixture: Evenly spread the cream cheese mixture over the graham cracker crust, smoothing it out with a spatula.

4. Prepare the Pudding Layer: In a separate bowl, whisk together the pistachio pudding mix and milk for about 2 minutes until thickened.

5. Layer the Pudding: Pour the pistachio pudding mixture over the cream cheese layer, spreading it evenly.

6. Add Toppings: Sprinkle the chopped pistachios over the pudding layer for added texture and flavor.

7. Chill: Cover the dish with plastic wrap and refrigerate for at least 2 hours to allow the bars to set properly.

8. Finish with Whipped Topping: Before serving, top with the remaining whipped topping and dust with powdered sugar, if desired.

9. Slice and Serve: Cut into squares and serve chilled.
