How to Make It
Coat a 6-inch square pan with cooking spray; dust pan with 1 teaspoon flour, and set aside.
Beat margarine at medium speed of an electric mixer until creamy; gradually add 1/4 cup plus 2 tablespoons sugar, beating well.
Combine milk and egg substitute, stirring well. Combine 3/4 cup flour, baking powder, and salt; add to margarine mixture alternately with milk mixture, beginning and ending with flour mixture. Mix after each addition. Stir in vanilla, and set aside.
