Roughly 2-3 cups of chopped rhubarb, enough to layer the bottom of a 9x13
1 boxed white cake mix
1 stick butter, melted
1 cup hot water
Heat oven to 350 degrees. I buttered my 9x13 pan and layered the chopped rhubarb on the bottom. Sprinkle the white cake mix over the top of the rhubarb.
(this is a pic from underneath)Drizzle melted butter then water over the top of rhubarb and cake mix.
Bake at 350 degrees for 45-50 minutes. Check the center of the cake by inserting a toothpick until it comes out clean.
* Next time I will stir in those little peaks of dry cake mix that didn't get hit with the melted butter and water, they left a bit of dry cake mix after it was baked.
Unfortunately I didn't get a picture before we dug in.
