Rhubarb Dump Cake

"Rhubarb Dump Cake is a delicious way to use up any rhubarb you have in your freezer. Dump cakes are so easy to make. There is no mixing needed hence the name. The scrumptious dessert only requires five ingredients. All you need is the fruit, sugar, dry cake mix, water and melted butter. The end result is something like a crisp or cobbler. Very cool! If you don't have any frozen rhubarb you can use fresh instead. Enjoy!"
