One box of Angel Food cake mix.
One can crushed pineapple (approx 2 cups)
Mix together and put in 9 x 13 glass pan. Bake at 350 degrees for 30 minutes
DO NOT GREASE PAN. Don't worry, it won't stick.
Serve with LOADS of fresh whipped cream. (I add 1/4 cup powdered sugar to each 1/2 pint of whipping cream, plus 1/2 tsp vanilla extract, Beat on high until stiff.)
WARNING: Do not decide that the batter looks so minimal you could really bake it in a 9 x 9 pan. Your oven will never be the same.
