Recipe by Bonnie Young

Simple easy recipe using a cake mix. It is very moist. Now another recipe to use up that wonderful rhubarb. You can use fresh or frozen rhubarb.

Too sweet and recipe doesn't say where to add the butter.... I added in little pieces on top of the rhubarb sugar mix - probably not the place because it just seems greasy in addition to being overly sweet. The next day the whole cake was a soggy mess. Was I supposed to keep it in the fridge? Might be better if I knew where/how to add the butter and how to keep the cake from becoming soggy....
