Posted: 11/13/2007 - Sprinkle the brown sugar evenly over the bottom of two 8-inch round cake pans and pour the butter evenly over the sugar. In each pan, arrange the pineapple slices in a single layer over the sugar and place a cherry in the center of each slice. In a large bowl, combine the cake mix, water, oil, and eggs; beat until well combined. Evenly divide the batter between the two pans and bake for 30 to 33 minutes, or until a wooden toothpick inserted in the center of each comes out clean. Let the cakes stand for 5 minutes.
