Rhubarb Almost Dump Cake

From Kraft. An "almost" dump cake, as most call for just dumping the cake mix over the rhubarb, then drizzling over the butter and water (instead of mixing them together first). This is also good served cold: bake ahead of time then cool completely - refrigerate until ready to serve.

Ingredients

• 1  lb fresh rhubarb, chopped (about 4 cups)
