- 1 pound fresh rhubarb, sliced into little ¼-inch pieces (trust me, fresh is best here for that perfect tart bite)

- 1 (3 ounce) box of strawberry Jell-O – this is the secret weapon for that amazing fruity flavor
- 1 box of yellow cake mix – the standard 15.25 ounce size is perfect

How to Make 5 Ingredient Rhubarb Dump Cake
Alright, here’s where the magic happens! This cake practically makes itself, but follow these steps carefully for perfect results every time. The key? No stirring – I promise it’ll work!
Step 1: Prep the Rhubarb and Pan
First things first – preheat that oven to 350°F (175°C). While it’s heating up, grab your 9×13-inch baking dish and give it a good buttering. Don’t be shy with it – this prevents sticking and adds flavor! Now spread your sliced rhubarb evenly across the bottom. I like to pretend I’m making a little rhubarb carpet – just one single layer covering every inch.
Step 2: Layer the Ingredients
Here comes the fun part – the dumping! Sprinkle the sugar evenly over the rhubarb. Next comes the strawberry Jell-O (oh, that smell takes me back to childhood!). Finally, pour the entire box of cake mix right on top. Now here’s the crucial part – don’t stir! I know it’s tempting, but resist! The layers will work their magic in the oven.
Step 3: Add Liquids and Bake
Mix together your water and melted butter (I just do this right in the measuring cup), then slowly pour it all over the top. Again – no stirring! Pop it in the oven and let it bake for about 45 minutes. You’ll know it’s done when the top is golden and the rhubarb is tender when poked with a fork. Your kitchen will smell absolutely heavenly!

Tips for the Best 5 Ingredient Rhubarb Dump Cake
After making this rhubarb dump cake more times than I can count, I’ve picked up some tricks that’ll guarantee perfect results every time. First – if fresh rhubarb’s out of season, frozen works great! Just thaw and drain it well first. That powdery cake mix layer? Totally normal – just gently press those dry spots down with a fork when it comes out of the oven.
The biggest mistake I see? People stirring the layers! Resist that urge – the magic happens when you let everything bake undisturbed. And if you want extra crispy edges (my favorite part!), bake it in a metal pan rather than glass. These little tweaks make all the difference!
Common Questions About 5 Ingredient Rhubarb Dump Cake
I get so many questions about this recipe, so let’s tackle the big ones! First up – yes, you can absolutely use frozen rhubarb. Just thaw it completely and give it a good squeeze to get rid of that extra liquid. If you see powdery spots after baking, don’t panic! That’s totally normal. Just press those areas down gently with a fork – the steam from the cake will help moisten it up.
Not a fan of strawberry Jell-O? No problem! Raspberry or even cherry work beautifully. And to prevent a soggy cake, the number one rule is: don’t stir! Let the layers do their thing in the oven. Trust me, it works every time.
Serving and Storing 5 Ingredient Rhubarb Dump Cake
Oh, you have to serve this warm! It’s an absolute dream with a big scoop of vanilla ice cream melting over the top – that hot-and-cold combo is just perfection. Any leftovers? Just cover the pan and pop it in the fridge. It’ll stay delicious for about 3 days, though I doubt it’ll last that long!
