Preheat the oven to 350 degrees. Prepare a 9 by 13 inch baking pan with cooking spray and set aside.

In a medium bowl, cream the butter until smooth. Add flour, white sugar, salt, and chopped nuts. Mix until well combined. Press into the prepared baking pan.

Bake for 8-12 minutes, until the crust is lightly browned. Allow to cool.

Once the crust has cooled, Add the cream cheese to a large bowl and cream with a hand mixer. Add powdered sugar and 4 ounces of the cool whip. Spread on top of the cooled crust.

Combine the pudding with the milk and mix according to package directions. Spread the pudding on top of the cream cheese layer. Allow to set just a few minutes.

Spread the remaining cool whip on top of the pudding and top with additional nuts if you care to. Serve up immediately or this dessert is a great one that can be prepped a few days ahead.
