Blueberry Dump Cake Recipe: A dump cake is one of those magical desserts that feels almost too easy to be real. Picture this: a buttery, crumbly topping paired with juicy fruit filling underneath—no mixing bowls, no complicated prep, just dump, bake, and enjoy. That’s the beauty of a dump cake.
The term “dump cake” might not sound glamorous, but the results definitely are. It’s named for the method—dump everything into a baking dish and let the oven do the rest. No need to mix. No fuss. Just delicious layers of flavor. Most recipes use canned pie filling and a boxed cake mix, making it a shortcut dessert that’s still full of homemade charm.
This dessert bridges the gap between cobblers and cakes. It’s crisp on top like a cobbler, moist in the middle like a cake, and filled with that sticky-sweet fruit layer you can’t resist. The best part? You don’t need to be an experienced baker. It’s practically fail-proof.

Ingredients You’ll Need
Core Ingredients
You won’t need to raid the grocery store for this one. The classic blueberry dump cake uses just four main ingredients:
- Blueberry Pie Filling (2 cans, 21 oz each): This is the heart of the dessert. It gives you that jammy, rich fruit layer. You can use homemade pie filling too if you’re up for it.
- Yellow Cake Mix (1 box, about 15.25 oz): This gives the dessert its golden, crisp topping. White cake mix works too, but yellow gives a buttery richness.
- Unsalted Butter (1 cup, sliced into thin pads): Butter is the magic that crisps the top. Don’t substitute with oil—it won’t give the same texture.
- Optional: Fresh Blueberries (1/2 cup): Sprinkle these on top of the pie filling for bursts of real fruit flavor and texture.
That’s it. Four simple ingredients that come together into something way more delicious than the sum of its parts.
Optional Add-ins for Enhanced Flavor
Want to jazz it up a bit? Here are a few optional ingredients to take it to the next level:
- Lemon zest (1 tsp): Adds brightness and cuts through the sweetness.
- Chopped nuts (like pecans or walnuts): For a crunchy contrast.
- Cinnamon (1/2 tsp): Gives it a cozy, spiced flavor.
- Vanilla extract (1 tsp): Deepens the flavor subtly.
- Cream cheese dollops (about 4 oz, cubed): Add this on top of the pie filling for a cheesecake twist.
The beauty of a dump cake is how easy it is to customize. Don’t be afraid to experiment based on what you have.
Kitchen Tools You’ll Need
You really don’t need a lot to make a blueberry dump cake. Just a few basics:
- 9×13-inch Baking Dish: This size works perfectly for spreading the layers evenly.
- Butter Knife or Mandoline: For slicing butter into thin pads.
- Spatula or Spoon: Just for spreading out the filling.
- Oven Mitts: Safety first!
You’ll also want some parchment paper or non-stick spray if your baking dish isn’t non-stick. That’ll make serving and cleaning up even easier.
Step-by-Step Guide to Making Blueberry Dump Cake
Step 1: Preheat Your Oven and Prepare Baking Dish
Before you do anything else, get your oven preheating to 350°F (175°C). You want it fully heated before your cake goes in so it bakes evenly.
While the oven heats, grab your 9×13-inch baking dish. If it’s not non-stick, give it a quick spray with non-stick cooking spray or line it with parchment paper. This helps with easy serving later—and avoids any baked-on mess.
Prepping your dish is important even if it seems like a small step. The butter and fruit will get bubbly as they bake, and you want to make sure everything lifts out cleanly when it’s time to serve. Trust me, scraping a delicious cake out of a sticky dish is no fun.
Step 2: Spread the Blueberry Pie Filling
Now, crack open those two cans of blueberry pie filling and pour them directly into the prepared baking dish. Use a spatula or spoon to spread it out evenly so every bite has a bit of that sweet, jammy fruit.
If you’re using fresh blueberries, now’s the time to sprinkle them on top. This adds a burst of texture and natural fruitiness to balance the syrupy filling. Feel free to add lemon zest here too—it brightens the flavor and cuts through the sweetness.
Don’t overthink this part. Just spread and go. The oven will take care of the magic later.
Step 3: Sprinkle the Cake Mix Evenly
This is the step that gives the dump cake its signature topping. Open your box of yellow cake mix and evenly sprinkle the dry mix over the blueberry layer. Don’t mix it in—just shake it out and use your hands or a spoon to smooth it across the top.
Think of it like a blanket of flavor covering the berries. You want an even layer, but it doesn’t need to be perfect. A few gaps or clumps won’t hurt. What’s important is to avoid large mounds of cake mix, as they might not bake through fully.
Pro tip: if you want the topping to be a bit crispier and golden, you can lightly pat the mix down without pressing too hard. Just enough to get it level and even.
At this point, your dessert is really starting to take shape. And the best part? You still haven’t had to mix a thing.
Step 4: Add Butter Slices for Perfect Crispiness
Here’s where the magic happens.
Take your cold, unsalted butter and slice it into thin pats—around 1/8 to 1/4 inch thick. You’ll need about 1 cup (2 sticks) total. Place the slices over the top of the cake mix, spacing them as evenly as possible. The goal is to cover most of the cake mix surface so the butter melts and soaks through the mix as it bakes.
Some people melt the butter and pour it on instead—but that often leads to uneven coverage and dry spots. Sliced butter melts slowly and evenly, giving you that rich, buttery top layer that’s crisp in all the right places.
Make sure you cover the corners too. That’s where dryness can sneak in.
Once the butter is in place, your cake is ready for the oven!
Step 5: Bake to Golden Perfection
Now the fun part: baking.
Slide your baking dish into the preheated oven at 350°F (175°C) and bake for 45 to 50 minutes. You’ll know it’s ready when:
- The top is golden brown and bubbly
- The edges are crisp
- You can see blueberry filling bubbling up around the sides
Resist the urge to stir or poke at it while it bakes. Let it do its thing undisturbed. The top will turn into a crunchy, buttery crust, while the filling underneath stays gooey and rich.
If you notice that one side is browning faster, rotate the dish halfway through baking. Every oven has its quirks, so this helps ensure even cooking.
Once done, take it out and let it cool for about 10–15 minutes. This allows the filling to set a little, making it easier to serve.
You can serve it warm right out of the dish, or let it cool completely for a firmer texture. Either way, it’s absolutely delicious.
Tips for the Perfect Dump Cake
How to Avoid Dry Spots
One of the most common mistakes people make with dump cake is ending up with dry patches of cake mix on the top. You know, those floury-looking spots that didn’t quite bake through? Don’t worry—it’s fixable.
Here’s how to avoid them:
- Slice butter instead of pouring melted butter – as mentioned earlier, sliced butter ensures even melting and better coverage.
- Cover all corners – dry spots tend to show up in the edges, so make sure you place butter slices there too.
- Add a touch of moisture if needed – a light drizzle of milk or cream over especially dry spots before baking can help.
Another sneaky trick? Use a spoon to lightly press down the cake mix once you’ve added the butter. Don’t mix it, just tamp it down so there are no big mounds of dry mix.
Should You Stir a Dump Cake?
Absolutely not. In fact, stirring ruins the magic of a dump cake. The whole idea is to let the layers stay separate—fruit on the bottom, cake mix and butter on top.
When you stir, you end up with a weird, soggy cake that doesn’t have the crisp topping or gooey center. If you’re tempted to mix because you see dry cake mix, just adjust the butter coverage instead.
Let the oven do the work. Trust the process. The beauty of dump cake is in its simplicity—and that means no stirring allowed.
How to Make it More Moist and Flavorful
Want your dump cake to be extra gooey and rich? Here are a few flavor-boosting tips:
- Add a splash of milk or cream over the top before baking—just a few tablespoons will soak into the cake and make it more tender.
- Use a mix of pie filling and fresh berries. The fresh fruit adds moisture and texture.
- Add a touch of flavor extract. A teaspoon of vanilla or almond extract stirred into the pie filling layer adds complexity.
- Incorporate cream cheese. Dollops of cream cheese over the fruit layer make it tangy, rich, and almost like a cheesecake-layered dessert.
Remember, this dessert is super forgiving. You can play around with it and tweak it until you find your perfect version.
Variations You’ll Want to Try
Mixed Berry Dump Cake
If you’re the kind of person who loves a little bit of everything, a mixed berry dump cake is your dream come true. Simply swap out the blueberry pie filling with a mixed berry pie filling—or make your own blend using canned or fresh raspberries, blackberries, and strawberries.
You’ll get a more complex flavor that’s both tart and sweet, with juicy pops of fruit in every bite. This version is especially good during the summer when fresh berries are in season. Add a hint of cinnamon or nutmeg to the cake mix for a warm, cozy twist.
And the color? Absolutely stunning. The mix of red, blue, and purple makes it a show-stopper for guests, potlucks, or family dinners. Don’t forget the scoop of vanilla ice cream on top—chef’s kiss!
Blueberry Lemon Zest Cake
Want to brighten up the rich sweetness of blueberries? Add lemon zest and a splash of lemon juice to the pie filling before you layer it into the dish. Lemon pairs beautifully with blueberries and gives the dessert a refreshing tang.
For extra flair, use a lemon cake mix instead of yellow. The result is a zesty, fruity dessert that’s light, sweet, and full of citrusy sunshine. Great for spring gatherings, baby showers, or when you’re just craving something with a little zing.
A drizzle of lemon glaze over the top after baking will take it to bakery-level good. And it’s still just as easy to make—dump, bake, and enjoy.
Gluten-Free or Vegan Options
The beauty of dump cake is its flexibility—even those with dietary restrictions can enjoy it. Here’s how:
For a gluten-free version:
- Use a certified gluten-free cake mix (like King Arthur or Betty Crocker).
- Make sure your pie filling is also gluten-free (most are, but double-check the label).
For a vegan version:
- Use a vegan-friendly cake mix (check for no dairy or eggs in the ingredients).
- Substitute the butter with plant-based margarine or vegan butter slices.
- Make sure the pie filling doesn’t contain animal-derived products like gelatin (again, most don’t, but always check).
You’ll still get all the flavor and texture, with none of the ingredients you’re avoiding. It’s that kind of inclusive dessert that can bring everyone to the table.
Serving Suggestions
Best Ways to Serve It
You’ve made your dump cake. It smells amazing. Now what?
Well, dump cake is best served warm—not piping hot, but just enough that the filling is gooey and the top is crisp. Spoon it straight from the baking dish into individual bowls.
Here are a few top ways to serve it:
- Warm with vanilla ice cream – The cold ice cream melts into the hot cake… pure magic.
- With whipped cream – A dollop on top adds lightness and elegance.
- With a dusting of powdered sugar – Simple but pretty if you’re serving guests.
Want to get fancy? Add a few fresh blueberries or mint leaves on top. That little garnish makes it look like you spent way more time than you did.
Ice Cream or Whipped Cream Topping?
Can’t decide between ice cream or whipped cream? Why not both?
Here’s how they stack up:
| Topping | Pros | Best For |
|---|---|---|
| Vanilla Ice Cream | Creamy, cool, melts into warm cake | Classic pairing, dessert lovers |
| Whipped Cream | Light, airy, balances richness | Lighter dessert fans |
| Both | Ultimate indulgence | When you’re going all out |
Ice cream adds decadence, while whipped cream adds elegance. No matter which you choose, you can’t go wrong. Blueberry dump cake is a versatile base for all your dessert toppings.
Storage and Reheating Tips
How to Store Leftovers Properly
If you somehow manage to have leftovers (a rare thing!), storing your dump cake is easy.
- Let it cool completely before covering.
- Store it in the baking dish with plastic wrap or foil, or transfer to an airtight container.
- Keep it in the refrigerator for up to 4-5 days.
You can also store it room temperature for a day, but only if your kitchen isn’t too warm. The fruit and butter can go bad quickly if not kept cool.
Pro tip: Keep the topping crisp by storing it uncovered for the first few hours. Then cover once fully cool.
Best Ways to Reheat without Drying It Out
When you’re ready for round two (or three), here’s how to reheat it:
In the oven:
- Preheat oven to 325°F (160°C)
- Cover the dish with foil to prevent over-browning
- Bake for 10–15 minutes until warmed through
In the microwave:
- Scoop a serving into a microwave-safe bowl
- Heat on medium power for 30–45 seconds
- Be careful not to overdo it—microwaves can make the cake rubbery
To bring back the fresh-baked feel, add a tiny drizzle of butter or milk before reheating. This keeps the cake moist and flavorful.
