Meanwhile, make pecan pie filling and spiced-cream frosting: In 2-quart saucepan, combine granulated sugar, brown sugar and cornstarch. Stir in corn syrup, melted butter, salt and eggs. Cook over medium heat, stirring constantly, just until mixture begins to boil; remove from heat. Stir in toasted pecans and vanilla. Let stand 10 minutes; refrigerate 1 hour or until thickened.
