I've heard this recipe called "The Next Best Thing To Robert Redford Dessert", "The Next Best Thing To Sex Dessert", "Better Than Sex Dessert" & I'm sure it has many other names. Personally, being better than Robert Redford in my opinion doesn't take much...now if it was "The Next Best Thing To Ian Somerhalder (or Adam Levine)"...well, anyway, the point is this is a fairly simple dessert that tastes INCREDIBLE!! I got the recipe from the wife of an old boss.
I know you won't be surprised to hear I've modified it a bit. I've increased the powdered sugar, cream cheese & cool whip so that that layer would be thicker in a 9 x 13 pan. You could cut the amounts of these 3 ingredients in 1/2 if you want a thinner layer. I also came across a picture of this dessert made with BOTH a layer of chocolate & a layer of lemon pudding. I'm not a big fan of lemon pudding, but it might be interesting to put double pudding layers in. I don't see any reason you couldn't use other flavors of pudding as well.
Robert Redford Dessert
1 cup flour
1/3 cup nuts, optional
1 stick of margarine, melted
2 cups powdered sugar
16 oz of cream cheese
2 cups of cool whip

2 3/4 cups milk
cool whip to top with (the recipe uses a total of 2 tubs of cool whip)
Mix flour, nuts & margarine & press into bottom of a 9 x 13 pan. Bake at 350 for 10-12 minutes. Cool. Mix powdered sugar, cream cheese & cool whip. Place over cooled crust. Beat pudding & milk til smooth & thick. Place over previous layer. Top with whipped cream.
Refrigerate for several hours or over night.
