The Easiest 4-Ingredient Strawberry Rhubarb Dump Cake Recipe
Prepare for a delightful treat that’s as simple as it is delicious! This 4-Ingredient Rhubarb Dump Cake is a culinary marvel, striking the perfect balance between vibrant sweetness and a pleasant tang. It’s the ultimate hassle-free dessert, delivering big flavors with minimal effort, making it ideal for busy weeknights or impromptu gatherings.
At its heart, tart rhubarb mingles beautifully with sweet strawberry jelly, creating a rich, jammy fruit layer that bubbles up invitingly during baking. This fruity foundation is then crowned with a buttery, golden cake mix topping that transforms into a soft, crumbly crust. As it bakes, the rhubarb softens to perfection, offering a tender counterpoint to the rich, crunchy topping.
The texture of this dessert is truly special—it’s more akin to a rustic cobbler or fruit crumble than a traditional fluffy cake. You’ll find a luscious, jammy fruit base enveloped by a golden, buttery topping that provides a delightful textural contrast. If you’re envisioning a light and airy sheet cake, this isn’t it, and that’s precisely what makes this dump cake recipe so uniquely charming and satisfying.
For the ultimate cozy treat, serve this dump cake warm, ideally with a generous scoop of creamy vanilla ice cream or a dollop of fresh whipped cream. The contrast of warm, tangy fruit and cool, sweet dairy is simply irresistible!

Essential Ingredient Notes & Substitution Tips
This section provides detailed notes on each ingredient and offers valuable substitution options to help you tailor this incredible rhubarb dump cake to your pantry and preferences. For precise measurements, the complete list of ingredients, and step-by-step instructions, please refer to the printable recipe card located at the end of this post.
- Rhubarb: Fresh rhubarb is highly recommended for its vibrant flavor and firm texture. Remember to always remove and discard any leaves, as they are poisonous. Wash the stalks thoroughly and slice them into uniform 1-inch chunks to ensure even cooking. If fresh rhubarb isn’t available, you can use frozen rhubarb without thawing; simply add about 5-10 minutes to the baking time. If using canned rhubarb, check the label carefully; if it already contains strawberry or is sweetened, you might need to reduce the amount of strawberry jelly or adjust the overall sweetness. Reduce baking time for canned rhubarb to around 30 minutes, or until the cake mix topping is lightly browned.
- Strawberry Jelly: Opt for strawberry jelly over jam or preserves for this recipe. Jelly provides a smoother, sweeter, and more consistent filling that perfectly coats the tart rhubarb, creating that classic jammy texture. If you only have jam or preserves on hand, you can still use them, but be aware that the final filling might have a slightly different texture and color, and possibly less sweetness due to less added sugar in some preserves.
- Yellow Cake Mix: I typically use Betty Crocker yellow cake mix, but any favorite brand will work perfectly. The key here is to use only the dry cake mix powder; disregard any additional ingredients listed on the box for preparing a traditional cake. A white cake mix can be easily swapped in for a similar result, and even a vanilla or butter pecan cake mix could add interesting flavor nuances.
- Butter: For the best crumbly topping, it’s crucial to use cold butter, cut into small cubes. Cold butter, when mixed with the dry cake mix, creates those wonderful pockets of butter that melt slowly during baking, resulting in a light, crisp, and golden crumb. If you’re using unsalted butter, a small pinch of salt (about ¼ teaspoon) added to the cake mix will help balance the sweetness and enhance the overall flavor of the topping.
How to Make Rhubarb Dump Cake: Step-by-Step Instructions

Step 1: Prep the Oven and Dish. Begin by preheating your oven to 350°F (175°C). Lightly coat a 9×13-inch baking dish with nonstick cooking spray to prevent sticking and ensure easy cleanup.
Step 2: Create the Buttery Topping. In a medium-sized bowl, combine the dry yellow cake mix with the cold, cubed butter. Use a fork, a pastry blender, or even your clean hands (which I find works best!) to thoroughly mix the butter into the cake mix until the mixture resembles coarse, sandy crumbs. This ensures a perfectly distributed, golden topping.
Step 3: Prepare the Fruity Filling. Spread the chopped rhubarb evenly across the bottom of your prepared baking dish. Next, pour the strawberry jelly over the rhubarb. Use a spoon to gently stir and coat all the rhubarb pieces thoroughly with the jelly. This creates a vibrant and flavorful base.
Step 4: Top and Bake. Evenly sprinkle the butter-cake mix crumble over the entire surface of the rhubarb and jelly mixture. Bake the dump cake uncovered in the preheated oven for 45 minutes, or until the topping is beautifully golden brown and the fruit filling is visibly bubbly around the edges.
Step 5: Serve and Enjoy. Allow the rhubarb dump cake to cool for a few minutes before serving. It’s best enjoyed warm, ideally complemented by a generous scoop of vanilla ice cream or a dollop of fresh whipped cream for an extra touch of indulgence. Enjoy this incredibly easy and flavorful dessert!
Why Mix the Butter Into the Cake Mix (Instead of Layering)?
You might notice that this strawberry rhubarb dump cake recipe deviates slightly from some traditional dump cake methods, which often suggest simply layering slices of cold butter on top of the dry cake mix or pouring melted butter over it. While those methods can work, I’ve found that mixing cold, cubed butter directly into the dry cake mix until it forms a coarse crumble yields vastly superior results.
This “crumbly” approach, though requiring a touch more effort, ensures significantly better coverage. You won’t find any dry, powdery patches of cake mix after baking. Instead, every bite delivers a consistently golden, buttery, and perfectly crisp topping. Furthermore, this method prevents sogginess; when melted butter is poured or slices melt unevenly, it can pool in certain areas, leading to a greasy or heavy texture. By creating a uniform crumble, the butter bakes up evenly across the entire surface, resulting in a delightful, airy crunch that perfectly complements the tender, jammy fruit filling beneath. It’s a small step that makes a big difference in the final texture and taste of your dump cake.
Storage & Reheating Tips for Your Rhubarb Dump Cake
Properly storing your rhubarb dump cake ensures you can enjoy its deliciousness for days to come. Always allow the cake to cool completely to room temperature before storing.
- Fridge: Store any leftover dump cake in an airtight container in the refrigerator for up to 4 days. Be aware that the crumbly topping will naturally soften slightly over time due to moisture from the fruit. To reheat individual servings, simply microwave for about 30-60 seconds, or until warmed through. You can also warm it in a preheated oven at 300°F (150°C) for 10-15 minutes for a slightly crisper topping.
- Freezing: For longer storage, bake the rhubarb dump cake as directed and let it cool fully. You can then freeze it directly in the foil baking pan (if using a disposable one) or transfer it to a freezer-safe container. Wrap it tightly first with plastic wrap, then with aluminum foil, to prevent freezer burn. It will keep well in the freezer for up to 3 months. When ready to enjoy, thaw overnight in the refrigerator and then reheat as desired.
Expert Tips for Dump Cake Success
Achieve perfection with your rhubarb dump cake every time by following these simple, yet crucial, tips:
- Use Cold Butter: This is a non-negotiable step for the best topping texture. Cold butter creates pockets within the cake mix, leading to a flakier, crispier crumble rather than a dense or greasy one.
- Don’t Skip Greasing the Dish: Rhubarb and jelly can become quite sticky as they bake and bubble. A good coating of nonstick spray will save you a lot of scrubbing later and ensure your dump cake comes out cleanly.
- Chop Rhubarb Evenly: Uniformly sized rhubarb chunks are essential for even cooking. This prevents some pieces from being too tough while others are overly soft, ensuring every bite has the perfect texture.
- Monitor for Doneness: While 45 minutes is a good guideline, ovens can vary. Keep an eye on your dump cake towards the end of baking. The top should be golden brown, and the fruit filling should be visibly bubbly around the edges, indicating the rhubarb is tender and the jelly is set.
- Allow to Cool Slightly: While tempting to dive in immediately, letting the dump cake cool for 10-15 minutes allows the fruit filling to set a bit more, making for cleaner slices and a less runny experience.
Delicious Additions and Flavor Variations
This 4-ingredient rhubarb dump cake is fantastic as is, but it also serves as an excellent canvas for customization. Get creative with these delicious additions and variations to put your own spin on this classic dessert:
- Warm Spiced Flavor: Introduce a hint of warmth by adding 1 teaspoon of ground cardamom or a ½ teaspoon of ground ginger to the rhubarb and jelly mixture. Cinnamon or a pinch of nutmeg would also be lovely.
- Extra Crunch: For added texture, mix about ½ cup of chopped walnuts, pecans, or almonds into the cake mix topping before sprinkling it over the fruit. Toasted coconut flakes could also add a tropical twist.
- Deepen the Flavor: Stir 1 teaspoon of pure vanilla extract into the strawberry jelly and rhubarb mixture to enhance the overall aroma and depth of flavor of the filling. Almond extract could also provide an interesting twist.
- Fruit Jelly Swaps: While strawberry jelly is classic, experiment with other fruit jellies or jams! Raspberry jelly would offer a delightful tart-sweet contrast, while cherry or mixed berry jam could introduce new flavor dimensions.
- Citrus Zest: Add the zest of one lemon or orange to the rhubarb mixture for a bright, fresh note that perfectly complements the fruit.
- Serve with Different Toppings: Beyond vanilla ice cream, consider serving with a scoop of lemon sorbet, a drizzle of caramel sauce, a sprinkle of powdered sugar, or even a dollop of crème fraîche for a sophisticated touch.
