For JenK and anyone else who has never made one, it's SOOOO easy.
1 box Yellow Cake Mix
2 cans Crushed Pineapple
2 sticks Butter
1/2 cup Brown Sugar
Mix the brown sugar into the crushed pineapple. Dump mixture into a baking dish (7x11 or 9x13, dependent on how thick you prefer your cake). Dump the cake mix over the pineapple mixture completely covering it. You'll only use about half of the cake mix. Melt the butter and then pour over the cake mixture until it's completely covered. Bake in a 400°F oven for approximately 30 minutes or until the top of the cake is golden brown.
I prefer pineapple, but this recipe could be used with any fresh fruit, compote, or chutney. This is an incredibly quick dessert and is super rich, so a healthy spoonful over a scoop of vanilla ice cream is more than plenty to satisfy your sweet tooth.
