In a large mixing bowl, combine the softened cream cheese, the remaining 1 cup granulated sugar, the carton of sour cream, and the 2 tablespoons flour. Beat mixture with an electric mixer on low to medium speed until combined. Add eggs all at once. Beat until just combined (dont overbeat). Stir in the whipping cream, orange peel, the 1 tablespoon juice, and the 1 teaspoon vanilla (filling will be slightly thin).
