Preheat the oven to 350℉.
In the baking pan, empty the crushed pineapples and the juice. Next, place dollops of the cherries across the pineapples.
Sprinkle the cake mix across the top of the cherries and pineapple. Pour the melted butter as even as possible across the top of the cake.
Place in the oven and bake for 40 minutes or until the top is golden. Allow to cool about 15-20 minutes then serve and enjoy!
