Ingredients
Gather ’round, here’s what you’ll need for this magical concoction:
- 3 cups diced rhubarb: The star of the show! Fresh is wonderful, but see the FAQ for frozen options. Gives that perfect tart counterpoint to the sweet.
- 1 box vanilla cake mix (standard size, about 15.25 oz): You don’t even open it until it’s dump time! This is the base that turns everything into cakey goodness.
- ½ cup melted butter (that’s one stick!): Gotta have that butter to bind everything and create that lovely crisp topping.
- 1 cup sugar: Rhubarb is tart, so this sweetness balances it out beautifully. Adjust slightly if your rhubarb is super sweet or super tart.
How to Make It
Okay, deep breaths. Are you ready for this unbelievably simple process? It’s almost too easy.
Step 1: Prep Your Dish & Combine
Grab a standard 9×13 inch baking dish. You don’t even really need to grease it because of all that wonderful butter, but a quick spray won’t hurt if you’re worried about sticking. Now, here’s the fun part: literally just dump the diced rhubarb right into the bottom of the dish. Sprinkle the cup of sugar evenly over the rhubarb. Next, sprinkle the dry cake mix right on top of the sugar and rhubarb. Last but not least, drizzle that ½ cup of melted butter as evenly as you can over the top of the dry cake mix. No stirring needed! The magic happens in the oven.
Step 2: Bake Until Golden & Bubbly
Pop that dish into a preheated oven at 350°F (175°C). Let it bake for about 40 minutes. You’ll know it’s ready when the top is golden brown and the rhubarb underneath is bubbly and tender. The butter and cake mix will transform into a delicious cakey-cobbler-like topping.
Substitutions & Additions
Want to get a little creative? Here are some ideas:
- Cake Mix Swap: Try a yellow cake mix, white cake mix, or even a strawberry cake mix for a fun twist.
- Add Berries: Toss in a cup of fresh or frozen strawberries, raspberries, or blueberries along with the rhubarb for a classic pairing.
- Spices: Sprinkle a little cinnamon or nutmeg over the rhubarb before adding the dry mix.
- Nuts: Sprinkle some chopped nuts (like walnuts or pecans) over the butter layer for added crunch.
- Lemon Zest: A little lemon zest added with the rhubarb can really brighten the flavor.
Tips for Success
This recipe is pretty foolproof, but here are a couple of things to keep in mind:
- Even Butter Drizzle: Try to drizzle the melted butter as evenly as possible over the dry cake mix. This helps the cake mix absorb the fat and get that lovely texture. Don’t worry about covering every single bit, but aim for good coverage.
- Rhubarb Size: Dice the rhubarb into roughly ½ to 1-inch pieces. This helps ensure it cooks through nicely in the baking time.
- Don’t Stir! I know it’s tempting, but seriously, resist the urge to stir everything together before baking. The magic happens when the ingredients layer and cook together as designed.
- Serving: While delicious warm from the oven, letting it sit for 10-15 minutes helps it set up slightly before serving.
Storage Instructions
If you miraculously have leftovers (which is a big IF in my house!), you can store Rhubarb Dump Cake.
Simply cover the baking dish tightly with plastic wrap or aluminum foil, or transfer leftovers to an airtight container. Store it in the refrigerator for 3-4 days. You can gently reheat individual portions in the microwave.
FAQ
- Can I use frozen rhubarb? Yes! Thaw the frozen rhubarb completely and drain off any excess liquid before adding it to the baking dish.
- What size baking dish should I use? A standard 9×13 inch baking dish works perfectly for this amount.
- Should I serve it warm or cold? It’s delicious both ways, but serving it warm with a scoop of vanilla ice cream or a dollop of whipped cream is pure heaven!
- Can I reduce the sugar? Rhubarb is quite tart. While you can slightly reduce the sugar (maybe down to ¾ cup), I wouldn’t recommend cutting too much, or the dessert might be overly sour.
