Apple Harvest Cake

In a large mixing bowl, beat 2 cups sugar, oil, eggs, orange juice and vanilla until well blended. Combine the flour, baking powder and salt; gradually beat into sugar mixture until blended. Stir in apples. Spread half of the batter into a greased 13-in. x 9-in. baking dish. Combine cinnamon and remaining sugar; sprinkle over batter. Carefully spread remaining batter over the top. Bake at 350° for 40-50 minutes or until a toothpick inserted near the center comes out clean. Cool on a wire rack. Garnish with whipped cream and additional cinnamon if desired. Yiel
