Pineapple Dump Sheet Cake is my kind of low-effort dessert: a juicy pineapple base with a buttery cake-mix topping that bakes up golden and a little crisp in spots. It’s sweet, simple, and very much in that old-school American potluck dessert lane.
I like this version because the pineapple layer stays soft and spoonable, almost like a warm fruit cobbler underneath. The topping gets toasty and rich, and you can keep it plain or add coconut and nuts when you want a little more texture.
This is one I make when I need a 9×13 dessert that feeds a group and doesn’t require frosting or fussy steps. For me, it’s best served warm with vanilla ice cream, especially for casual weekends and holiday tables.
Why You’ll Love This Recipe
Fast and easy: It’s a true dump-and-bake style dessert, with no mixer and no complicated prep.
That buttery topping: The cake mix and butter bake into a rich, golden top that’s crisp on the edges and tender where it meets the fruit.
Big-pan friendly: A 9×13 pan means neat slices, easy serving, and it travels well for gatherings.
Pineapple forward: Using both crushed pineapple and tidbits gives you a saucy base with little bites of fruit throughout.
Easy to tweak: Coconut, nuts, cherries, and even swapping the cake mix are all simple changes that work without reworking the recipe.
Ingredients You’ll Need
Pineapple Base
- Crushed pineapple in juice: I use the canned kind in juice (not syrup) and keep the juice in the pan. That liquid is what makes the base thick and spoonable as it bakes.
- Pineapple tidbits: These add little chunks so the fruit layer isn’t just smooth. Drain them well so the base doesn’t get too loose.
- Light brown sugar: This sweetens the fruit and gives it that caramel-ish flavor that tastes right with pineapple.
- Cornstarch (optional): If you like a thicker fruit layer, use it. I’ll add it if my pineapple seems extra juicy or I just want cleaner slices.
- Vanilla extract: It rounds out the canned pineapple flavor and makes it taste more “dessert” to me.
- Ground cinnamon (optional): Just a little is nice here, especially if you’re adding nuts. You can skip it if you want a straight pineapple flavor.
- Kosher salt: Don’t skip the salt. It keeps the base from tasting flat and helps the topping taste more buttery.
Cake Topping
- Yellow cake mix: I stick with yellow cake mix for the classic dump cake taste. Butter cake mix or vanilla cake mix both work too.
- Unsalted butter: This is what turns dry cake mix into that golden, crumbly topping. Unsalted lets you control the salt level.
- Sweetened shredded coconut (optional): If you like a little chew and a toasty top, add it. It also leans into that pineapple-coconut combo.
- Chopped pecans or walnuts (optional): Nuts add crunch and keep the topping from feeling too soft. Pecans are my favorite here, but walnuts work fine.
For Serving
- Vanilla ice cream: This is the simplest, most reliable way to serve it. The cold ice cream against the warm cake is hard to beat.
- Whipped cream: Great if you want something lighter than ice cream. I like it best with a slightly warm slice.
Recipe Instructions
- Preheat the oven: Heat the oven to 350°F. Grease a 9×13-inch baking pan.
- Mix the fruit: Add the crushed pineapple (with its juice) and the drained tidbits to the pan. Stir in the brown sugar, cornstarch if using, vanilla, cinnamon if using, and salt.
- Spread the base: Spread the pineapple mixture into an even layer so it bakes up consistently.
- Add the cake mix: Sprinkle the dry cake mix evenly over the fruit. Don’t mix it into the pineapple layer.
- Add the toppings: Sprinkle coconut and chopped nuts over the cake mix if you’re using them.
- Add the butter: Drizzle the melted butter evenly over the top, moistening as much of the cake mix as you can. Aim for an even coverage so you don’t end up with big dry patches.
- Bake: Bake for 45 to 50 minutes, until the top is deeply golden and the edges are bubbling.
- Cool: Cool for 15 to 20 minutes so the fruit layer thickens up a bit before slicing.
- Serve: Serve warm with vanilla ice cream or whipped cream.
Some of my tips!
This is the part that really makes a difference. If you only read one section, make it this one because this is where I share the little trick that helps the recipe turn out so well.
Recipe Tips & Tricks
Drain the tidbits well. The crushed pineapple brings plenty of liquid on its own. If the tidbits are watery, the base can end up looser than you want.
Spread the cake mix evenly. Take a few extra seconds to get it into the corners. Thin spots can get too dark, and thicker spots can stay powdery.
Try cold butter if you want a crisper top. Melted butter is easy, but cold butter sliced thin tends to bake up more crumbly and crisp. Either way works.
Use cornstarch if you want cleaner slices. It’s optional, but it helps the pineapple layer set up more like a pie filling. I usually use it when I know I’ll be serving this in neat squares.
Let it cool a bit before serving. Right out of the oven, the fruit layer is very loose. Give it 15 to 20 minutes and it thickens up noticeably.
Make some touches!
There are plenty of easy ways to serve this depending on the occasion. Keep it simple, or add a few small touches to make it feel a little more special.
Serving Suggestions
- Ice cream: Serve it warm with vanilla ice cream. I like a generous scoop because the pineapple layer is pretty saucy.
- Whipped cream: A big spoonful of whipped cream is great if you want something lighter. It also looks nice if you’re serving this on a platter.
- Toasted coconut: If you skipped coconut in the topping, sprinkle a little toasted coconut over each slice. It adds flavor and a little crunch.
- Cherries: Add a few drained maraschino cherries on the side (or in the slice) for a pineapple upside-down cake feel. It’s especially nice for holiday dessert tables.
Save it for later
This section covers how to store leftovers and what parts of the recipe you can prepare ahead of time.
Storage and Make Ahead
Store leftovers covered in the fridge for up to 3 days. The topping softens a bit as it sits, but the flavor stays great.
To rewarm, heat individual portions in the microwave, or warm the whole pan in a 300°F oven until heated through. If you want the top a little crisper again, the oven works better than the microwave.
You can also bake it earlier in the day and serve it warm later. Just let it cool, cover it, then rewarm before serving.
If you want to freeze it, freeze portions in an airtight container, then thaw in the fridge overnight. Rewarm gently so the fruit layer doesn’t get too hot before the center warms through.
A few quick answers
This section covers a few extra details that may help before you head to the recipe card.
Recipe FAQs
Do I really not mix the cake mix into the fruit?
Right, don’t mix it in. The dry cake mix sits on top and bakes into the topping as the butter soaks through.
Can I use pineapple chunks instead of tidbits?
Yes. Chunks work the same way, just with bigger pieces of fruit. I’d still drain them well.
What cake mix works best?
Yellow cake mix is the classic choice and what I usually use. Butter cake mix or vanilla cake mix both work if that’s what you have.
How do I know it’s done?
Look for a deeply golden top and bubbling around the edges. If you see big dry patches of cake mix, it usually just needs a few more minutes (or those spots didn’t get enough butter).
Can I add cherries for a pineapple upside-down style?
Yes, add about 1/2 cup drained maraschino cherries to the pineapple layer. It gives you that pineapple-upside-down vibe without changing anything else.
