I made this and brought it to work. Everyone loved it and it was all gone in no time. It may have been just a little too lemony for me so I may try it again and just use a regular yellow cake mix instead of the lemon cake mix. All in all though it was very good. Thanks for sharing the recipe.

Wonderful! A great way to use up an "oversupply" of summer rhubarb! My husband and son ate it and they usually won't touch rhubarb. I have also made it with different flavors of jello and cake mixes. (ex: strawberry cake mix and strawberry jello)
