Blueberry Dump Cake has become my most requested pudding at the little weekend club I run here in Bath. I’m Mary—most know me as “The Pudding Lady.” My passion for baking started in a humble pantry where golden syrup clung to every tin and flour seemed to settle in every crack. I learned early that a good dessert fixes more than you think, and that no custard can save a bad bake. From licking the spoon as a child to now serving polished treacle puddings and jam-soaked Victoria sponges, I’ve spent a lifetime exploring the joys of old-fashioned desserts.
This Blueberry Dump Cake recipe is the epitome of easy baking—juicy blueberries, yellow cake mix, and melted butter transform into a bubbling, golden dessert with little effort. Whether you serve it warm with ice cream or chilled from the fridge, this dump cake never fails to delight. If you’re after a dish that’s fuss-free, family-friendly, and just a little bit magical, this one’s for you.

What is a Blueberry Dump Cake?
What Makes It a “Dump” Cake?
A dump cake earns its name from its simple prep method—you just pour or “dump” all the ingredients straight into the baking dish. There’s no need for mixing, kneading, or creaming butter and sugar. The magic happens in the oven as the butter melts into the cake mix and mingles with the fruit, creating a golden, crisp topping over gooey blueberry filling.
Unlike traditional cakes that require precision, a blueberry dump cake embraces the rustic, effortless style. That’s exactly what makes it perfect for beginner bakers and busy households.

The Origins and Popularity of Dump Cakes
Dump cakes rose to fame in the 1960s, a time when boxed cake mixes became a pantry essential in many homes. These recipes were a way to whip up a dessert quickly with pantry items on hand. Over time, variations exploded—cherry, apple, peach, and yes, blueberry dump cake became beloved versions.
Today, this version is especially favored in the summer months when blueberries are in season. Still, thanks to canned and frozen options, it’s a year-round go-to. And if you’re after a simple, nostalgic dessert, a warm blueberry dump cake straight from the oven hits the spot.
Why Blueberry Is a Favorite Dump Cake Flavor
There’s something irresistible about blueberries. Their bright, sweet-tart flavor contrasts perfectly with the rich, buttery cake topping. Plus, they bring a vibrant color to the dessert table. Whether you’re using fresh, frozen, or canned blueberry pie filling, the result is always rich, fruity, and comforting.
This is why blueberry dump cake continues to be one of the most popular variations—it’s easy, tasty, and looks like you tried way harder than you did.

Ingredients
Core Ingredients (Blueberries, Cake Mix, Butter)
What makes a blueberry dump cake so special is its effortless simplicity. You only need three essential ingredients to create a warm, bubbly masterpiece:
| Ingredient | Purpose |
|---|---|
| Blueberries (fresh, frozen, or canned) | The fruity foundation of the cake |
| Yellow or white boxed cake mix | Creates the crisp, buttery topping |
| Unsalted butter (melted or sliced) | Binds and crisps the dry mix |
These pantry-friendly staples are why this dessert is often dubbed the lazy cake or no-mix cake—all you do is layer and bake.
If you’re using canned blueberry pie filling, it brings sweetness and a thick texture. Fresh or frozen blueberries give a more tart, juicy flavor, but you might want to add a bit of sugar or cornstarch to adjust consistency.

Canned vs. Fresh vs. Frozen Blueberries: What Works Best?
Each blueberry option can work in this recipe—but they do have some differences:
| Type | Pros | Considerations |
|---|---|---|
| Canned | Already sweetened and thick | Can be overly sweet for some preferences |
| Fresh | Bright flavor, in-season freshness | May need added sugar and thickener |
| Frozen | Available year-round, budget-friendly | Can release extra moisture—thaw first |
Tip: If you’re using frozen blueberries, toss them in a tablespoon of flour to prevent them from sinking too deeply in the dish—just like we do in other bakes like muffins or pancakes.
Optional Add-ins for Flavor and Texture (Lemon Zest, Vanilla, Nuts)
Want to take your blueberry dump cake to the next level? Add a few flavor boosters:
- Lemon zest or juice: Brightens the blueberries
- Vanilla extract: Adds warmth and depth
- Cinnamon or nutmeg: Adds a cozy, fall-inspired twist
- Chopped pecans or walnuts: Give a delightful crunch to the topping
You can also drizzle sweetened condensed milk before baking for extra richness. Don’t be afraid to customize—dump cake is all about ease and creativity.

Step-by-Step Guide to Making Blueberry Dump Cake
Preparing Your Baking Dish the Right Way
Before you start dumping ingredients, you’ll want to prep your baking dish properly to avoid sticking and uneven baking. Here’s what to do:
- Use a 9×13-inch glass or ceramic baking dish.
- Lightly coat the pan with butter or non-stick spray to keep the edges from burning.
- If using fresh blueberries, spread them evenly at the bottom and sprinkle with a bit of sugar and lemon juice to enhance the flavor.
This setup ensures your blueberry dump cake bakes evenly and releases easily once cooled.

Layering Technique: What Goes in First?
This isn’t your average cake batter. The order of layers in a dump cake recipe is important:
- Blueberries or pie filling: Spread this layer across the bottom. If using fresh berries, add 1-2 tablespoons of sugar and 1 tablespoon of cornstarch to help thicken the juice as it bakes.
- Cake mix: Sprinkle the dry mix evenly over the fruit—do not stir!
- Butter: Either slice and lay over the top or drizzle melted butter across the dry cake mix to moisten it.
Pro Tip: Use cold butter slices for a crumbly topping, or melted butter for a smoother, golden crust.
The secret to the perfect blueberry dump cake texture is resisting the urge to mix. Just layer and bake.
Tips for Perfect Baking Every Time
To get that signature golden top and bubbling berry bottom, follow these baking tips:
- Bake at 350°F (175°C) for 40–50 minutes.
- Check that the edges are crisp and the blueberries are bubbling.
- If using frozen fruit, add 10 extra minutes to your bake time.
- For an even bake, rotate your pan halfway through.
If the top starts to brown too fast, tent it loosely with foil for the last 10–15 minutes of baking.

Tips to Customize Your Blueberry Dump Cake
Gluten-Free, Vegan, and Dairy-Free Versions
One of the greatest perks of blueberry dump cake is its versatility—you can easily switch up the ingredients to suit your taste or what’s in your pantry. Whether you’re gluten-sensitive, vegan, or dairy-free, you can still indulge in this easy dessert.
Here’s how:
| Dietary Need | Simple Swap | Notes |
|---|---|---|
| Gluten-Free | Use a certified gluten-free cake mix | Brands like King Arthur or Betty Crocker have options |
| Dairy-Free | Replace butter with plant-based margarine or coconut oil | Use one with high fat content for crispiness |
| Vegan | Combine dairy-free butter + vegan cake mix | Check labels to avoid egg powder or milk solids |
And don’t worry—none of these swaps compromise the texture or flavor. You’ll still get the gooey blueberry center with that golden, crisp topping.
Check out Blueberry Crumble Cheesecake—it’s another great recipe to modify for plant-based diets.
Swapping the Cake Mix: Vanilla, Lemon, or Spice?
While classic yellow cake mix is the go-to choice, that doesn’t mean you’re limited. You can easily change the flavor profile of your blueberry dump cake by swapping out the mix:
- Lemon cake mix: Adds brightness and pairs well with tart blueberries
- Vanilla or white cake mix: More neutral, allows the fruit to shine
- Spice cake mix: Great for fall—think cinnamon, nutmeg, and cozy flavors
Want more texture? Add a handful of oats, graham cracker crumbs, or crushed shortbread cookies on top of the cake mix before baking.
Topping Options: Whipped Cream, Ice Cream, or Crumble
What you serve on top makes a big difference in the experience. Here are some popular toppings for blueberry dump cake:
- Whipped cream: Light and airy, great for warm servings
- Vanilla ice cream: Melts into the cake for extra richness
- Greek yogurt: A tangy twist that balances the sweetness
- Brown sugar crumble: Mix brown sugar, butter, and flour, then sprinkle on top before baking for a crunchy bite
You can even drizzle with honey, maple syrup, or blueberry glaze for a decorative finish.

Common Mistakes to Avoid When Making Dump Cake
Overbaking or Undercooking: Spotting the Signs
Getting the timing just right is critical to a perfect blueberry dump cake. Overbake it, and you’ll have a dry, crumbly top. Undercook it, and it stays gooey in a bad way.
How to tell it’s ready:
- The edges are deep golden brown and slightly crisp.
- The blueberry filling is bubbling around the edges.
- A few dry cake spots on top are fine—they’ll still be soft and buttery.
Tip: If your oven runs hot, start checking at the 35-minute mark. Every oven is different, so trust your eyes more than the clock.

Using Too Much or Too Little Butter
Butter is a make-or-break element for blueberry dump cake. Use too much and you’ll drown the top—too little and the cake mix will remain powdery.
How much is just right?
Stick with 1 cup (2 sticks) of unsalted butter per standard 9×13 pan. If you’re slicing it into pats instead of melting it, space them evenly over the cake mix so every inch gets some buttery coverage.
Warning: Don’t try to “healthify” the recipe by cutting the butter. This cake relies on fat to achieve its texture.
Mixing When You Shouldn’t: Why It’s Called a Dump Cake
Many first-timers think they’re supposed to mix the ingredients—don’t do it.
Mixing changes the entire texture. Instead of a layered dessert with a crisp top and juicy base, you’ll end up with a gummy mess. The magic of blueberry dump cake lies in the layering technique—dump and bake, no whisking required.
If you’re looking for a more traditional mixed batter cake, you might enjoy options like coffee cake or muffins instead.
Storing and Reheating Your Blueberry Dump Cake
Does Blueberry Dump Cake Need to Be Refrigerated?
Yes, it does—especially if you plan to keep it for more than a few hours. Because this dessert contains fruit, it’s prone to spoilage if left at room temperature too long. After cooling completely, store your blueberry dump cake in the refrigerator using one of the following methods:
- Cover the baking dish tightly with foil or plastic wrap to keep the cake fresh
- Transfer to an airtight container if you’ve sliced it into portions
It can be stored in the refrigerator for up to 4 days while staying fresh and flavorful. After that, the texture starts to break down, and the berries may get overly soft.
Tip: Always let it cool completely before refrigerating to prevent condensation buildup, which can lead to a soggy top.
How Long Can Dump Cake Sit Out?
You can safely leave your blueberry dump cake out for about 2 hours at room temperature. If you’re serving it at a party or cookout, keep an eye on the time—especially during warmer months.
If it’s been out for over 4 hours in a warm kitchen, it’s best to toss any leftovers to avoid food safety risks.

Best Ways to Reheat Without Drying It Out
When you’re ready for a second helping, you’ll want your blueberry dump cake to taste just as good as when it first came out of the oven. Here’s how to reheat it properly:
Oven Method (best for preserving texture):
- Preheat to 325°F (163°C)
- Cover the baking dish loosely with foil
- Heat for 10–15 minutes or until warm
Microwave (for individual portions):
- Place one slice in a microwave-safe dish
- Cover with a damp paper towel
- Heat on medium for 30–45 seconds
Avoid overheating, especially in the microwave, which can dry out the cake or make the filling rubbery.

Blueberry Dump Cake Troubleshooting FAQs
How Do You Know When a Dump Cake Is Done?
A perfectly baked blueberry dump cake has a golden top and bubbling fruit underneath. Still not sure? Here are a few clear signs:
- The edges should be deeply golden and just starting to pull away from the sides of the pan.
- The blueberry filling is bubbling, especially around the edges.
- A few dry patches of cake mix are okay—but most should be moist and crisp.
Use a spoon to gently lift a portion—the texture should be moist and cake-like, not raw or overly runny. If in doubt, bake it an extra 5–7 minutes and keep an eye on the top.
How Do I Keep My Blueberries From Sinking to the Bottom of a Cake?
This is a common question when using fresh blueberries in baked goods. In a blueberry dump cake, you typically layer fruit on the bottom, but if you want a more even distribution, here’s how to stop the sinking:
- Toss the blueberries with 1 tablespoon of flour before layering.
- Gently press some blueberries into the cake mix mid-layer.
- Use a thicker base (like pie filling) to suspend the berries better.
These techniques help suspend berries within the cake as it bakes instead of sinking and pooling.
Does Blueberry Dump Cake Need to Be Refrigerated?
Absolutely—especially if you’re not eating it the same day. Refrigeration helps prevent mold, spoilage, and mushy texture.
- Cool completely before refrigerating
- Wrap tightly with plastic wrap or transfer to an airtight container for optimal freshness
- Keeps fresh in the fridge for up to 4 days
Pro Tip: Refrigeration also helps the flavors meld, making the second-day slice even better.
How Long Can Dump Cake Sit Out?
Your blueberry dump cake can stay at room temperature for up to 2 hours. After that, bacteria can start to grow—especially in warmer weather. If you’re outdoors, try to serve it within one hour and store any leftovers promptly.
For safe storage:
- Avoid keeping it near heat sources
- Cover with foil if serving buffet-style
- Refrigerate leftovers immediately after the meal
