Rhubarb dump cake with jello is one of those old-school desserts I keep coming back to every spring.
Tart rhubarb. Sweet strawberry jello. Zero stress.
If you’ve ever made Rhubarb Dump Cake Recipes before, this one feels familiar but also a little more playful.
Why complicate dessert when a dump-and-bake cake does the job so well, right?
This is the kind of cake I make when guests are coming and I still want time to drink my tea.
Spring and early summer is peak rhubarb season here, and honestly this recipe screams potlucks, Sunday lunches, and last-minute family dinners.
What Makes This Rhubarb Dump Cake With Jello Special?
First thing first.
This is not a fancy bakery cake.
It’s cozy. Messy. A little rustic.
The strawberry jello melts into the rhubarb and creates this jammy layer that reminds me of Strawberry Rhubarb Recipes without all the chopping and stirring.
Some people compare it to Rhubarb Magic Cake or even Rhubarb Upside Down Cake With Cake Mix, but this one stays simple. And simple food always wins.
Ingredients Needed To Make Jello Centric Rhubarb Dump Cake
Here’s what I use every single time.
- 4 cups fresh rhubarb, chopped into ½-inch pieces
- 1 cup granulated sugar (adjust if your rhubarb is very tart)
- 1 packet (3 oz) strawberry jello
- 1 box yellow cake mix (plain works best)
- ¾ cup unsalted butter, melted
- 1 teaspoon vanilla extract (optional but nice)
- A pinch of salt
That’s it.
No eggs. No mixing bowls full of batter.
This is why Rhubarb Dump Cake With Jello shows up on my table more than Rhubarb Custard Bars or layered Jello Cake Recipes.
Instructions To Make Rhubarb Dump Cake With Jello
Step 1: Prep the pan
Preheat your oven to 350°F (180°C).
Grab a 9×13 baking dish.
Lightly grease it. Don’t skip this or you’ll regret it later, trust me.
Step 2: Build the rhubarb layer
Evenly distribute the chopped rhubarb across the dish’s bottom.
Sprinkle the sugar over it.
Now pour the dry strawberry jello powder evenly on top.
Do not mix.
I know you want to.
Just don’t.
This layer is what makes this Rhubarb Cake With Strawberry Jello taste like summer in a spoon.
Step 3: Add the cake mix
Open the box and sprinkle the dry cake mix evenly over the rhubarb and jello layer.
Use your hands if needed.
Clumps are okay. Life isn’t perfect and neither is cake.
This step feels very similar to other Rhubarb And Cake Mix Recipes, and that’s why it works.
Step 4: Butter time
Drizzle the melted butter slowly over the entire surface.
Try to cover as much cake mix as possible.
Some dry spots will remain and that’s fine.
Add vanilla extract over the top if using.
A tiny pinch of salt too. It wakes everything up.
Step 5: Bake
Bake uncovered for 45 to 50 minutes.
The top should be golden brown and the edges bubbly.
Your kitchen will smell unreal right now.
Let it rest for at least 15 minutes before serving.
If you cut it too early it will be sloppy, but honestly sloppy is part of the charm.
How This Rhubarb Dump Cake Tastes (And Why People Love It)
The bottom is soft and tangy.
The middle turns into a jam-like strawberry rhubarb layer.
The top is buttery, crisp, and cake-like.
It’s not dry.
It’s not soggy either.
Its somewhere in between, in a good way.
This is why Rhubarb Dump Cake keeps beating more complicated Strawberry Rhubarb Cake Recipes in real homes.
Variations You Can Try
Want to play around? I do sometimes.
- Swap strawberry jello for raspberry jello for deeper flavor
- Use white cake mix for a sweeter finish

Just saying.
Is This Rhubarb Dump Cake A Healthy Dessert?
Let’s be honest.
This is not one of those Healthy Rhubarb Recipes you eat every day.
But rhubarb itself is high in fiber and naturally low in calories.
Balance matters.
Cake happens.

Cover leftovers tightly.
Store in the fridge for up to 4 days.
