Dump Cake Ingredients:
Most of these ingredients are simple and ones that are good to have in the pantry. Rhubarb is the only one that’s a little different. As always I’m going to give you substation suggestions just in case you don’t have everything and don’t want to run to the grocery store.
- Rhubarb: Fresh or frozen will both work great. If you’re using frozen rhubarb be sure to let it thaw first.
- Boxed Cake Mix: A yellow cake mix is a popular option, but I really love using a white cake mix too. And if you want to get really creative you can use a chocolate cake mix!
- Jell-o: Any red Jell-o will work. Strawberry and raspberry are my favorites. Cherry is also fantastic.
- Fruit Pie Filling: Blueberry is my go-to. Cherry, raspberry, or mixed berry are great options too. If you really don’t want to use pie filling, you can leave it out, but I think it’s much better!
- Lemon Lime Soda: I really like using soda pop in my Dutch oven cobblers and dump cakes. Lemon-lime is the best variety, or you can use ginger ale. If you don’t have pop on hand, you can always use water or pineapple juice.
How to Make Rhubarb Dump Cake:
Dump cake recipes are so easy to make! They are called dump cakes for a good reason. You literally “dump” everything in the pan and bake it. There is no need to stir the layers together. Magic happens while they bake!
How do you prepare rhubarb? The stalk is the part of the rhubarb you’ll eat. The leaves are poisonous (at a very low level) so you’ll want to discard them. Trim about two inches below the leaves and about an inch of the root end of the stalk. Wash the rhubarb using a vegetable scrubber.
How to dice rhubarb? Once the stalks are clean pull any strings off the stalks. Use a knife to dice the stalks into about 1/2 inch pieces for making pies, dump cakes, and most other desserts. If you are cooking or stewing the rhubarb it can be left in bigger chunks.
Step 1: Layer diced rhubarb in the bottom of a greased 9 x 13-inch baking dish. Evenly pour pie filling over the sliced rhubarb. Sprinkle dry Jell-o powder over the fruit pie filling. No stirring!
Step 2: Pour lemon-lime soda over the fruit. Don’t stir.
Step 3: Evenly sprinkle a boxed cake mix over the top of the fruit and Jell-O layers.
Step 4: Drizzle melted butter over the cake mix. You want to make sure it’s as evenly drizzled as possible because the butter is going to give it nice crisp pieces. They’re my favorite!
Step 5: Bake the dump cake. The cake mix will get a little bit crisp on top and the cobbler on the bottom will poke through that cake mix layer on the top! You can let the dessert cool a little bit and then serve it, or refrigerate it and let it completely cool before serving it. Either way, it’s best with a big spoonful of freshly whipped cream or vanilla ice cream!
Yes! Rhubarb freezes beautifully! Clean rhubarb and dice. Spread it on a baking sheet and freeze until firm. Remove from the baking sheet and freeze it for up to a year in an airtight container. Fresh or frozen rhubarb will work for this recipe. Allow the rhubarb to thaw before making the
Yes. Since it has fruit filling in it you’ll need to keep it in the fridge. It will keep up to four days.
Yes. Freeze leftovers for up to three months. Thaw dump the cake and reheat it in the microwave when you’re ready to serve it. Honestly, making a dump cake is so easy that I recommend making it and serving it fresh.
