Cut cookie dough in half.  For crust, press half of dough into the bottom of a greased 8 inch square baking pan.  In a mixing bowl, beat cream cheese, sugar and egg until smooth and spread over crust.  Crumble  the  remaining  dough over top.  Bake at 350 for 35 minutes, or until a toothpick inserted in the middle comes out clean.  Cool on a wire rack.  Cut into bars and serve.

2 cups of your favorite  home-make chocolate chip  cookie dough can be substituted for the tube refrigerated dough.  This makes a yummy bar with soft cream cheese filling.
