Easy Blueberry Dump Cake Recipe (Just 5 Ingredients!) is my go to trick for the nights when I want something sweet but I do not want a sink full of dishes. You know those days when dinner is done, everyone is still a little snacky, and you need dessert to feel like a win? This is that recipe. It is cozy, buttery, and bursting with blueberry flavor, but it is also almost impossible to mess up. If you can open a couple of packages and turn on the oven, you are in business. 
What Exactly is a Dump Cake Anyway?
A dump cake is exactly what it sounds like. You dump the ingredients into a baking dish, layer by layer, and bake. No mixing bowl, no hand mixer, no complicated steps. It is not quite a cake like you would frost, and it is not quite a cobbler either. It lands somewhere in the best possible middle, with a jammy fruit base and a golden topping that gets crisp on the edges and soft in the center.
I started making dump cakes years ago when I needed a last minute dessert for unexpected guests. I was honestly skeptical. But when I pulled it out of the oven and saw that bubbly blueberry layer peeking through the buttery cake topping, I was sold. Now it is one of those recipes I keep in my back pocket for potlucks, movie nights, or when I just want a warm bowl of something sweet.
If you love easy bakes like this, you might also like this cozy twist on the same idea: caramel apple mascarpone dump cake. It has that same low effort vibe but feels extra special.
What ingredients do I need to make a blueberry dump cake?
This is the part everyone loves because it is truly a short list. For this Delicious Easy Blueberry Dump Cake Recipe with Just 5 Ingredients! you need only five things, and they are all easy to find.
My 5 ingredient shopping list
- Blueberry pie filling (usually 2 cans, or enough to cover the bottom of your baking dish)
- Crushed pineapple (1 can, drained just a little, more on that later)
- Yellow cake mix (1 box)
- Butter (1 stick, melted, or sliced thin if you prefer)
- Optional but counts as part of the five: fresh blueberries (I like a handful for extra pop) or swap this slot for chopped nuts if you want crunch
Quick note on the pineapple: I know it sounds a little random, but it adds a gentle tang and keeps the fruit layer from tasting too one note sweet. The blueberries still star, the pineapple just makes them brighter. If you are totally not into pineapple, you can skip it and use a second can of blueberry filling instead, but I really think the combo is worth trying once.
“I made this for a family dinner and everyone thought I spent way more time on it than I did. The blueberry layer was gooey, the top was buttery, and it was gone in ten minutes.”
And if you are in a blueberry mood in general, this one is a little more breakfasty but still dessert friendly: blueberry ricotta coffee cake. So good with coffee.
How to make a blueberry dump cake
This is where the magic happens, and it is honestly more like layering than baking. I make this when I want something warm and comforting without thinking too hard.
Step by step directions
- Preheat your oven to 350 F.
- Grab a 9×13 baking dish and lightly butter it or spray it.
- Spread the blueberry pie filling evenly across the bottom.
- Spoon the crushed pineapple over the blueberries. If your pineapple is super juicy, drain just a little so it is not soupy.
- If you are using that handful of fresh blueberries, scatter them over the top now.
- Sprinkle the dry cake mix evenly over everything. Do not stir. Just try to cover the fruit layer.
- Pour the melted butter evenly over the cake mix. I go slow and try to hit as much surface area as possible.
- Bake for 45 to 55 minutes, until the top looks golden and you can see the fruit bubbling around the edges.
- Let it cool for at least 15 minutes before scooping. It thickens as it sits.
Serving is my favorite part. I usually do a big spoonful in a bowl with vanilla ice cream. Whipped cream works too, and if you want to be a little fancy, a pinch of lemon zest over the top wakes up the blueberry flavor.

Pro Tips for Making the Best Blueberry Dump Cake
I have made this enough times to learn a few little things that make it turn out great every time. These are simple tweaks, not fussy chef stuff.
Small tweaks that make a big difference
Try to cover the cake mix with butter. Dry patches happen if the butter does not reach certain spots. If you notice a couple of dry areas halfway through baking, you can carefully drizzle a tiny bit more melted butter over those places.
Do not stir. I know it is tempting, but the layers matter. Stirring turns it gummy, and you lose that classic dump cake texture.
Let it rest. Straight out of the oven it is super hot and loose. After 15 to 20 minutes, it scoops like a dream and the flavors settle.
Watch the edges. When the fruit is bubbling around the sides, that is a good sign it is done. If the top is browning too fast, loosely cover with foil for the last 10 minutes.
Want more crunch? Sprinkle chopped pecans or sliced almonds over the buttered cake mix layer. That is optional, but it is really nice if you like texture.
Can I Use Frozen Blueberries In This Dump Cake Recipe?
Yes, you can, and it is a great move when fresh blueberries are expensive or not in season. But there is one catch: frozen blueberries add extra moisture as they bake.
Here is how I do it. If I am using frozen blueberries, I still like to use at least one can of blueberry pie filling for that thick, jammy base. Then I add 1 to 2 cups frozen blueberries on top. Do not thaw them first. Thawing makes them release even more juice and can make the bottom runny.
If you go heavy on frozen blueberries, consider skipping the pineapple or draining it really well. You want that bottom layer bubbly and saucy, not watery. And if it looks a little loose when it first comes out, do not panic. This cake firms up as it cools, especially after 20 to 30 minutes on the counter.
So yes, frozen works, and it still fits the spirit of a Delicious Easy Blueberry Dump Cake Recipe with Just 5 Ingredients! because you are not adding complicated steps. You are just making a smart swap.
Common Questions
Do I have to use yellow cake mix?
Nope. Yellow is classic, but white cake mix works too. Lemon cake mix is also amazing with blueberries if you like a brighter flavor.
How do I store leftovers?
Cover the dish and keep it in the fridge for up to 4 days. Reheat in the microwave or warm it in the oven until it is cozy again.
Can I make blueberry dump cake ahead of time?
Yes. You can bake it earlier in the day and rewarm it before serving. It is actually easier to slice after it has cooled for a bit.
Why is my topping still powdery?
Usually it is uneven butter coverage. Next time drizzle more slowly and try to coat the surface. If it happens mid bake, add a little more melted butter on the dry spots.
What do you serve with it?
Vanilla ice cream is the classic. Whipped cream is easy. Greek yogurt is surprisingly good if you want something less sweet.
