In a bowl, cut butter into flour until crumbly. Press into ungreased 13x9 pan. Bake at 350 for 18-22 min. or until set. Cool. In a mixing bowl, beat cream cheese and sugar until smooth. Fold in 1 cup cool whip. Spread over crust. In a mixing bowl, beat milk and pudding mixes on low speed for 2 min. Carefully spread over the cream cheese layer. Top with remaining cool whip (I don't like to put on this last layer of cool whip). I offer it if any one wants it, but it seems like too much and takes away from the other layers.
