Blessed with an over abundance of never ending rhubarb, I have tried many different ways to prepare it. Pie, bread, muffins, dessert sauce, Victoria Sauce and more, but this my friends, is Nirvana! So far this month I have baked two of these cakes and both were devoured by family and friends who gave them rave reviews. I looked for rhubarb cake recipes on the internet and found numerous variations of this upside down cake, but none of them contained fresh strawberries! They all had strawberry gelatin but no actual strawberries. I fixed that little problem by cutting back on the rhubarb and including two cups of fresh sliced strawberries. Using a cake mix cuts down the prep time with no loss of flavor. I was requested to make a third cake if time allows, so yes, this was a hit out of the ball park success!
