Why You Will Love This Recipe
It’s amazing how a simple box of cake mix can easily turn into a dessert with a streusel topping with just the help of some butter. Trust me this works, and all you do is place the butter over the top of the dry cake mix.
Rhubarb isn't the only fruit you can do this with. Add some strawberries to the rhubarb for a more sweet and tart taste.
Is it bad to eat cake for dinner? No??? Then good, because that is what I did for supper tonight.
Ingredients Needed
Chopped rhubarb - Pick it straight from the garden if you’re one of those lucky people with rhubarb. Don’t like rhubarb? Use your favorite fruit. Cherry pie filling or apple pie filling would work great.
Sugar - Regular granulated sugar. I do not use sugar substitutes in any of my recipes but if you know the conversions feel free to do so.
Yellow cake Mix - can sub sugar free cake mix if you like
Butter, melted - The best butter to use for baking is unsalted butter so you can control the amount of salt that goes into the recipe. For some dump cakes online they just call for pats of butter over the dry cake mix. That also works as well if you don’t want to melt it.
See recipe card below for a full list of ingredients and measurements.

Dollop some fresh whipped cream on top, Cool Whip, or serve it with Vanilla Bean Ice Cream Recipe
Make a pot of coffee or some Brown Sugar Shaken Espresso to drink while eating the cake.
Recipe FAQs
Dump cake is just a box of any store bought cake mix and some cold butter that has been layered on the top of the cake mix. You do not need to follow the back of the cake mix box for this type of recipe.
No you do not need to, I've seen people use canned fruit toppings or other types of frozen fruit like strawberries.
If the cake pan you have comes with a lid for the top use that or wrap the cake pan tightly in saran wrap.
The butter can make the cake a little gooey right as you take it out of the oven. It is best to let the cake sit out for awhile to set to prevent that from happening.

Abigail Baker says
Getting ready to mate this now but I've already cooked down my rhubarb so I'm going to lay the rhubarb in the pan and sprinkle just a tiny bit of sugar over top of it because it's a bit tart then do the cake mix and then do the butter I'm hoping that it will turn out right I will let you know

Jenna says
Of course, check their website for correct measurements though. Not really sure how much splenda you use.
Nancy says
Can you use Splenda instead of sugar for less points!
Mary says
I thought there would be a recipe for rhubarb dump cake and here I found it. I will be making it for work tomorrow. I am looking forward to making it in for my employees to try it!
Jenna says
Yes. White will work too.
Barb says
I'm assuming you could use a white cake mix as well. (That's what I have on hand)
Jenna says
Yes to both. Updated recipe. Thanks.
Lou Ann says
This recipe is in the oven now, but ingredient list says 1/2 sugar. I am assuming you mean 1/2 cup. Also, the ingredients says 1 and 1/2 stick melted butter, but direction says to pour 1 stick melted butter over cake mix. Just needs a little clarification. Hope it tastes as yummy as it smells. Thanks.
