This is one of my go-to recipes for rhubarb. Even my youngest son, who doesn’t like rhubarb, likes this cake. This dessert can be made with fresh or frozen rhubarb. If using frozen rhubarb, you will need to thaw and drain it prior to baking with it.

If you line the pan with parchment paper or aluminum foil before greasing or spraying with non-stick spray, it will make this cake easier to turn upside down

It’s so easy to make. You just mix chopped rhubarb with a package of dry jello and sugar. I used raspberry jello this time, but strawberry, cherry, and watermelon are also good. This recipe works well with regular or sugar-free jello. If you don’t want to use jello, you can leave it out and increase the amount of sugar to 1 cup. Cover the rhubarb layer with mini marshmallows (approximately 3 cups). I have cut up and used large marshmallows on occasion when I was out of mini marshmallows.

Prepare a yellow or white cake mix according to the package directions. I used a French vanilla cake mix this time. If you don’t want to use a pre-boxed mix, feel free to use your favorite homemade cake recipe. Pour the cake batter on top of the rhubarb and marshmallow layers.

This fills a 9″x 13″ pan pretty full. Be careful when putting it in the oven.
