Pineapple Angel Food Cake Recipe

Preheat oven to 350 degrees. Combine cake mix and pineapple, with juice, in large bowl and stir with a spoon until well combined. Spoon into an ungreased 9 x 13-inch baking pan. Bake 35 minutes. Let cool completely in pan. Run a thin, sharp knife around edges of cake before cutting. (I serve from the pan.) If desired, dust cooled cake with powdered sugar. Serve plain or with fat-free Cool Whip.
