1 pkg. yellow cake mix
1/2 c. butter
1 c. firmly packed brown sugar
1 can pineapple slices
Maraschino cherry halves
Whipped cream, if desired

Melt butter in a 9 x 13 inch pan. Sprinkle brown sugar evenly in pan. Drain pineapple; save the juice. Arrange pineapple and maraschino cherry halves on the sugar mixture. Add water to pineapple juice to make the amount of liquid needed for cake mix; mix as directed on box. Pour batter over pineapple.

Bake at 350 degrees for about 50 minutes, until cake pulls away from side of pan. Let stand for 5 minutes for topping to set. Then turn upside down onto a large platter. Serve warm, topped with whipped cream.
