Awesome! I did let the rhubarb sit in the sugar, jello and tapioca for a half hour and it had started to get nice and gooey by that time. Tasted fantastic, and easy to make. The crowd at work raved about it!

This was a hit!! I love that it uses 4 cups of rhubarb. I will be making this again and when I do, I will make it a more generous (heaping) 4 cups. It also does not need an hour to bake the cake. Following the baking instructions on the box will be adequate. I cut the time down to 45 minutes because the top of the cake was getting brown. Probably 40 minutes is enough.

Growing up my mom would make Strawberry & Rhubarb crisp and it was always my favourite dessert; this one is definitely its competition!! OMG this was amazing! The changes I made was adding a teaspoon of lemon extract to the wet ingredients for the cake mix, substituting 2 cups rhubarb with strawberries and mixing 1/2 the sugar in with the fruit because I like the tartness of rhubarb; and it was a hit!
