This recipe is wonderful. Very fast and easy to mix up can also use frozen rhubarb. Serve it nice and warm with some ice-cream or cool whip. The marshmallows give the cake a nice golden brown. Preparation time does not include time to clean and dice rhubarb. I put 12 for serving size according to the box, but I am sure you can get more out of a 9x13 inch pan. The recipe is sweet so a smaller piece may be better. Enjoy!

This was excellent and quick to whip up with some rhubarb I needed to use up. I told my mom about it and she said she had the recipe and it was called "My Man's Rhubarb Cake"

This is a very kid friendly desert to make in the kitchen. My family thought this desert was great. I have also given this recipe out, and so far everyone has loved it.

I wanted to try one of Canbesweet's recipes and chose this one. Rhubarb is hard to find in our town, but I had strawberries! I made the cake according to the recipe, but had the oil measured out but in time saw DO NOT add oil in capital letters. I served it with vanilla ice cream and it was a cross between strawberry shortcake and a strawberry sundae. Quite yummy and good for summer!
