Preheat oven to 350°.
Combine first 4 ingredients; set aside.
Combine milk, egg substitute, and margarine in a large bowl. Gradually add flour mixture, stirring until smooth. Stir in corn. Pour mixture into a 13- x 9-inch baking dish coated with cooking spray.
Bake, uncovered, at 350° for 40 to 45 minutes or until deep golden and set. Let stand 5 minutes before serving.
Tip: If fresh corn is out of season, you can use thawed and drained frozen whole-kernel corn.
