Step 1

Preheat oven to 350 degrees. Very lightly spray a 13x9x2-inch pan with nonstick cooking spray. Put butter in a pan and put the pan in the oven just until butter is melted (maybe 5 minutes).

Step 2

Remove pan from oven and evenly sprinkle brown sugar over melted butter. Arrange pineapple slices and maraschino cherries on top of brown sugar.

Step 3

Prepare cake mix (adding eggs, water and oil) as directed on package and pour batter evenly over fruit.

Step 4

Bake 50 minutes or until toothpick in center comes out clean.

Step 5

Let stand for 5 minutes (if you wait too much longer than that the cake will stick in the pan), then carefully invert onto a large serving plate.
