PREHEAT oven to 325° F.
BEAT eggs in large mixer bowl on high speed until foamy. Beat in flour, granulated sugar and brown sugar. Beat in butter. Stir in morsels and nuts. Spoon into pie shell.
BAKE for 55 to 60 minutes or until knife inserted halfway between edge and center comes out clean. Cool on wire rack. Serve warm with whipped cream, if desired.
* If using frozen pie shell, use deep-dish style, thawed completely. Bake on baking sheet; increase baking time slightly.
