Rhubarb Custard Upside-Down Cake - Ratings & Reviews

"If there was a cake called HEAVEN this would be it. I am not huge rhubarb fan but now I am because of this. I used a lemon flavored cake mix by mistake and it was great. It reminded me of lemon custard with that creamy addition and oh the cake too. It's easy and tastes like it took hours to make!!"
