Pineapple Dump Cake is my go to dessert for those nights when you want something sweet but you absolutely do not want a big mess in the kitchen. Maybe you had a long day, the sink is already full, or guests are on the way and you need a quick win. This is the kind of recipe that feels almost too easy, yet it comes out warm, buttery, and a little crispy on top. You do not need a mixer, fancy tools, or even much patience. If you can open a couple cans and sprinkle cake mix, you are good.
Why is it called a dump cake?
The name makes people laugh the first time they hear it, and honestly, that is part of the charm. A dump cake is called a dump cake because you basically dump the ingredients into the pan in layers and bake. No creaming butter and sugar. No beating eggs. No careful folding. You just layer, bake, and scoop.
With Pineapple Dump Cake, the whole idea is that the fruit and its juices create the base, the dry cake mix becomes the topping, and the butter melts through it all while baking. The oven does the heavy lifting, and you end up with something that tastes like a cobbler and a cake had a very happy vacation together.
One little tip from my own trial and error: do not stir the layers. It is tempting, I know. But if you stir, the cake mix can clump weirdly and you lose that golden, buttery topping everyone fights over.
And if you love pineapple desserts in general, you might also like this cozy tropical bake I make when I want something more classic: Hawaiian carrot pineapple cake. 
Why You Will Love this Easy Pineapple Dump Cake Recipe
I have made this for potlucks, lazy Sundays, and one time for a last minute “we are coming over in 30 minutes” text. It always works. Here is why I keep coming back to it.
What you will need
- Canned pineapple (crushed, tidbits, or chunks all work)
- Boxed yellow cake mix (or butter cake mix if you want it richer)
- Butter (melted or sliced thin)
- Optional extras like brown sugar, shredded coconut, or chopped nuts
I like crushed pineapple when I want more even sweetness in every bite, but pineapple chunks give you those juicy pockets that feel extra special. If you only have one can, you can still do it, but the dessert is best when there is enough fruit to keep the bottom nice and saucy.
How I make it at home
Preheat your oven to 350 F. Grab a 9 by 13 baking dish. Pour in your pineapple with the juice. Spread it out so it is nice and even.
Next, sprinkle the dry cake mix over the pineapple. Do not mix it in. Just make a smooth, even layer. Then add butter across the top. If you are using melted butter, drizzle it slowly so you cover as much of the surface as possible. If you are using sliced butter, lay the slices close together. This is the part that makes the top turn golden and crisp.
Bake for about 45 to 55 minutes, until the top looks deeply golden and you see bubbling around the edges. Let it cool for at least 15 minutes before scooping. It is molten right out of the oven, and the texture gets better after it settles.
This is one of those desserts where the serving matters. Warm Pineapple Dump Cake with vanilla ice cream is a full experience. The cold ice cream melts into the buttery topping and the pineapple sauce and it is just perfect.
I once brought this to a neighbor’s cookout and somebody actually wrote me the next day asking for the recipe. That is always my favorite kind of compliment.
“I made this last night with ice cream and my family kept going back for seconds. It was the easiest dessert I have baked in ages.”
Also, quick heads up for anyone who likes dump desserts in general: if you want to switch up the flavor sometime, this one is fun too: strawberry cheesecake dump dessert.
Recipe Variations
The classic Pineapple Dump Cake is already super easy, but you can tweak it depending on what you have in the pantry or what your crowd likes. I do this all the time, especially when I am trying to use up random baking bits.
Here are a few simple variations that actually work, not the fussy kind that sound good but fall apart.
Cherry pineapple: Add a can of cherry pie filling under the cake mix along with the pineapple. It turns into that retro cherry pineapple vibe in the best way.
Coconut pineapple: Sprinkle sweetened shredded coconut on top of the cake mix before adding butter. It gets lightly toasted and smells amazing.
Nutty crunch: Add chopped pecans or walnuts. I like pecans because they toast up buttery and rich.
Brown sugar boost: Sprinkle 2 to 3 tablespoons of brown sugar over the pineapple before the cake mix. It deepens the flavor and makes the edges extra caramel like.
Spiced version: A little cinnamon and a tiny pinch of salt on top of the cake mix can make the whole dessert taste more bakery style.
And if you are in a pineapple mood but want something totally different for breakfast or brunch, I have been loving this refreshing drink too: cucumber parsley pineapple and lemon smoothie.
How to Store
This is the part people always ask because Pineapple Dump Cake is so good warm, but it is also pretty nice the next day. The trick is keeping the topping from getting too soggy.
At room temp: If your house is cool and you plan to finish it the same day, you can cover the pan and leave it out for a few hours.
In the fridge: For anything beyond that, refrigerate it. Cover the baking dish tightly or move portions into a sealed container. It will keep well for about 4 days.
To reheat: My favorite way is the oven or toaster oven at 300 F for about 10 to 15 minutes. The microwave works, but the topping softens more.
Can you freeze it? Yes, you can freeze it, but I will be honest: the topping loses some of that crisp texture. If you do freeze it, wrap tightly and freeze up to 2 months. Thaw in the fridge overnight, then reheat in the oven to bring back some crunch.
One more small tip: if you know you will have leftovers, try not to add ice cream directly onto the whole pan. Scoop the cake into bowls first, then add ice cream. It helps keep the topping nicer for later.
For another make ahead friendly treat that stores well, these are fun if you want individual portions: apple crisp mini cheesecakes.

Common Questions
Do I drain the pineapple?
Nope. Keep the juice. The liquid is what helps create that saucy fruit layer under the cake mix.
Why is my cake mix still powdery on top?
Usually it means the butter did not cover enough of the surface. Next time, drizzle melted butter more evenly or use thinner slices placed closer together.
Can I use a different cake mix flavor?
Yes. Yellow is classic, but butter cake mix is richer. Pineapple Dump Cake also tastes great with vanilla, white cake mix, or even spice cake mix if you like a warmer flavor.
Do I have to use a 9 by 13 pan?
That size works best for even baking, but a similar sized casserole dish is fine. If you use a smaller dish, it will be thicker and may need a few extra minutes.
What should I serve with it?
Vanilla ice cream is the classic move. Whipped cream works too. If you want something extra, a sprinkle of toasted coconut on top looks cute and tastes great.
