Preheat oven to 350F and butter the 9x13 inch pan.

To make the crust, in a large bowl mix together the butter and all purpose flour, next add the pecans. Add the crust to the pan, press down, and bake in the oven at 350F for 15-20 minutes. Remove from the oven and allow to cool completely.

In another bowl, add the cream cheese, whipped topping, powdered sugar and mix together then set the bowl aside.

In another bowl, add the pudding, 3 cups of milk and mix until it forms a custard.

To layer, first add the cream cheese mixture (not all of it, because you will need some later), then add the all the custard, then finish with the rest of the cream cheese mixture. Garnish with pecans.

Place in the freezer overnight if you would like a frozen treat or place in the refrigerator for a couple of hours until chilled. Serve immediately.
