Empty peaches with the juice in the bottom of 9X13 pan. Sprinkle dry cake mix over top of peaches. Pour melted butter over the cake mix. It may not seem like enough liquid but the peach juice works its way up.
To "Dress it Up" before adding the butter sprinkle cake mix with coconut, nuts, brown sugar, any of all of them. Then pour the butter over it.
Bake at 375 degrees for 35-45 min. Add a small dollop of Cool Whip when serving. This could be made early in the day or even the night before.
