This Rhubarb Dump Cake is so easy, it literally requires no mixing! Just dump all the ingredients in the cake pan by layers and watch the cake/crisp do it's magic in the oven

Rhubarb Dump Cake

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 melted butter. Trust me this works, and all you do is place the butter over the top of the dry cake mix. You can also do this with pretty much any fruit you desire.

Is it bad to eat cake for dinner? No??? Then good, because that is what I did for supper tonight. The only thing I have growing in my garden right now is rhubarb. I've been dying to plant some herbs and tomatoes, but it has got to below freezing here the last couple of weeks. I'm afraid to plant anything else besides rhubarb.

What to Serve with Rhubarb Dump Cake? 

Dollop some fresh whipped cream on top, Cool Whip, or serve some vanilla ice cream with it. 

What Ingredients do I need for Rhubarb Dump Cake?  

In this section, you can find substitutes or suggestions for certain ingredients here. 

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.

    The only two I can see that would work are spice cake or white cake mix.

    I specifically don’t like yellow cake mix, can you suggest me something else as yellow cake mix's replacement?
