Hubby says he would eat it again. Extremely easy to make. I followed the recipe except for I only had 3 cups of rhubarb. Worked out okay but I would mix the cake mix with the water and then dump it over the rhubarb mixture so that there wouldn't be dry lumps. Turns out more like a cobbler than a cake. Thanks.
