This fruity dump cake takes the ice cream parlor favorite and turns it into a cozy, baked treat with soft caramelized bananas, tangy pineapple, and juicy strawberries under a crispy, golden top. What makes it special is how it builds up in layers—fruit juices soaking the bottom, crunchy cake on top, and all your favorite sundae add-ons to finish. Unlike fancier desserts that need exact measurements, this one's super forgiving and still packs amazing flavor in every bite.
The first time I whipped this up was for a backyard get-together when I needed something quick but impressive. My kitchen smelled absolutely amazing with the scent of fruit bubbling away under buttery cake. What really got me was watching everyone take their first bite—that awesome moment when they recognized those childhood flavors in a totally different package. Even my brother-in-law, who usually skips dessert completely, asked for another helping and wanted to know how to make it.
Delicious Ingredients
- Spotted bananas: They get super sweet when baked and develop rich caramel flavors throughout. Go for ones with dark spots for maximum sweetness.
- Ripe strawberries: They bring beautiful color and a hint of tang that cuts through the sweetness. Pick completely red berries for the best taste.
- Crushed pineapple with juice: Adds a tropical zip and needed moisture to the base. Its tartness balances the sweeter components perfectly.
- Yellow cake mix: Forms that amazing buttery top crust without any extra work. The powder transforms like magic in the oven.
- Butter: Turns the dry mix into a crunchy, melt-in-your-mouth topping. Go with unsalted so you can control the flavor better.
- Heavy whipping cream: Adds airy softness to the dense cake and gentle milky sweetness. It makes a nice texture contrast with the fruit bottom.
Simple Assembly
- Fruit Foundation:
- Cut ripe bananas into thin circles and put them in one layer across your buttered baking dish. They'll turn sweet and gooey as they bake, making little pockets of deliciousness throughout. Pour the whole can of crushed pineapple with all its juice right on top, making sure it's spread out evenly so every bite has that tropical tang.
- Berry Brilliance:
- Clean and slice your strawberries, then scatter them all over the pineapple. They'll get soft in the oven but still keep their shape, adding bright spots of color and jammy sweetness. Their slight sourness works perfectly with the super-sweet stuff around them.
- Cake Creation:
- Gently dust the dry cake mix over everything, making a nice even layer. Don't stir it in—keeping everything separate is key to getting those amazing texture differences that make dump cakes so good. The powder will soak up all the fruit juices from below as it bakes.
- Butter Blessing:
- Drizzle melted butter all over the cake mix, trying to cover as much as you can. Any dry patches will stay powdery instead of turning into that yummy crispy top. Take your time here—this step creates that magical contrast between the soft fruit base and the crunchy topping.
- Golden Perfection:
- Stick your creation in the hot oven and bake until the top turns golden and you see fruit juices bubbling around the edges. When you spot this, you'll know the cake mix has soaked up the butter and made a proper crust while all the fruits underneath have gotten nice and jammy together.

I've always loved anything banana split flavored because my grandpa would buy me ice cream every Sunday after we went to church. He always got the traditional banana split and let me steal bites from each section. When I made this dump cake version for the first time, I called him right away to share how it turned out. At 92 years old, he tried making it himself and told me it was "even better than the real thing"—which is huge coming from someone who knows his banana splits!
Tasty Companions
This flexible dessert works in all kinds of settings from casual to fancy. For family night, serve it slightly warm with a scoop of vanilla ice cream that slowly melts into the cake. When you have guests over, dish it up in pretty individual bowls topped with fresh whipped cream and some chocolate sauce drizzled on top for a fancier look. At summer parties, set it out next to a coffee station with different flavored creamers that complement all that fruity sweetness.
Fun Variations
Switch things up by trying different fruit combos based on what's in season. You can swap the strawberries for blueberries or blackberries to get deeper flavors and gorgeous purple-blue colors. If you're into coconut, throw some shredded coconut over the cake mix before adding the butter to give everything a tropical feel. Make a chocolate lover's version by using chocolate cake mix instead of yellow and sprinkle chocolate chips between the fruit and cake for pockets of melty goodness throughout.
Smart Storage
Keep any leftovers in the fridge, covered, where they'll stay good for about four days, though the texture changes a bit when chilled. The cake part gets more pudding-like while the fruit flavors get stronger, making it different but just as tasty. Warm up single portions in the microwave for 20-30 seconds if you want that just-baked feel, or eat it cold right from the fridge for a refreshing summer treat. If you need to plan ahead, you can put everything together except the whipped cream a day early, keep it in the fridge, then bake it just before you need it.
After making dump cakes for years now, I really appreciate how flexible and foolproof they are. This banana split version has become my go-to dish for group gatherings, and friends and family always ask me to bring it. There's something special about turning simple ingredients into a dessert that brings back such happy memories. The mix of warm, fruity bottom and cool, creamy toppings hits that perfect balance of temperatures and textures that makes everyone reach for just a little bit more.

Frequently Asked Questions
- → Can I substitute frozen fruit instead of fresh?
- For the strawberry layer, you can go with thawed, frozen ones if needed, but fresh bananas stay firm best. Frozen bananas might get too mushy, so stick to fresh. Fresh fruit for the topping will also keep it looking great.
- → What should I do if some fruits are missing?
- No worries! You can tweak it. Skip a fruit or swap it out. For example, leave out strawberries or use cherries or raspberries instead. The result will still be yummy, no matter what combo you choose.
- → Could I prepare this dessert in advance?
- Sure! Bake the base and cover it up for a day beforehand. But hold off on adding the whipped cream and fruit on top until right before serving—it’ll look fresher and the bananas won’t turn brown.
- → How do I know the cake is ready to come out of the oven?
- Keep an eye on the color. Once the top turns golden brown and doesn’t look wet or doughy, it’s good to go! You’ll also notice the edges bubbling gently from the fruit. If it browns too fast, loosely cover it with foil until fully baked.
- → Is there a way to make it without dairy?
- Definitely! Use a dairy-free cake mix, switch butter for coconut oil or plant-based butter, and top it with coconut whipped cream instead of regular. Just check the labels on the cake mix for hidden milk products.
