Rhubarb Dump Cake

"Rhubarb Dump Cake without jello is the one-pan dessert that uses either fresh rhubarb or frozen rhubarb, yellow cake mix, melted butter and a sprinkle of cinnamon & nutmeg. Serve with your favorite ice cream or scoop on freshly whipped cream. A great way to use up extra frozen rhubarb you have stored in the freezer. Made in one pan so minimal dished to wash! Crunchy, sweet cobbler-like topping over sweetened rhubarb is a delicious dessert. An easy recipe to get your kids to eat rhubarb."
