Springtime means rhubarb season, and even though it’s a vegetable, rhubarb is generally sweetened and served in desserts. Most of us are too busy to spend a lot of time in the kitchen, so it’s nice to have some quick and easy rhubarb desserts in our repertoire. The following Slow Cooker Rhubarb Dump Cake is perfect, since it takes only about 10 minutes to dice the rhubarb and less than five minutes to assemble. Once cooking, you can forget about it until dinnertime.

While dump desserts like this can be baked in the oven, this one doesn’t heat up the kitchen and this one doesn’t require any supervision while cooking. And it’s sooo good. Even rhubarb haters will like it. You can serve it with good vanilla ice cream or sweetened whipped cream.

12 Servings


1 pound fresh rhubarb, cut into 1/4" dice (4 cups)
3/4 cup sugar
1 3 oz. package raspberry or strawberry gelatin
1/2 cup water
15 1/4 ounces yellow cake Mix
1/4 cup melted butter

Sweetened whipped cream, or ice cream for serving

1. Dump the rhubarb into the bottom of a 3-4 quart slow cooker (preferably with a larger footprint rather than being tall).
2. Sprinkle the sugar over the rhubarb, then the gelatin over the sugar; pour the water over the gelatin.
3. Sprinkle the cake mix evenly over the mixture.
4. Pour the butter over the cake mix.
5. Cover the slow cooker, set to low, and let cook 4-6 hours or until the rhubarb is tender and the top portion is cooked through.
6. Tilt the lid slightly for about 15 minutes to evaporate any extra liquid that may have accumulated.
7. Serve with sweetened whipped cream or vanilla ice cream.
