1/2 cup flour
1/2 cup sugar
1/2 cup brown sugar
1 cup butter, melted and cooled
1 1/2 cup semisweet chocolate chips
1 cup chopped nuts (or use 2 1/2 cups chips instead of the nuts)

Preheat oven to 325 degrees F. Beat eggs well in large bowl. Add flour and sugars and mix until well blended. Stir in the melted butter. Add chips and nuts if using. Pour into unbaked pie shell, and bake at 325 for 55-65 minutes or until puffy and golden brown. Let cool at least 2 hours before serving.
