This easy Banana Split Dump Cake turns a beloved ice cream treat into a cozy, baked delight featuring caramelized bananas, sweet pineapple, and juicy strawberries under a crisp, buttery topping. What makes it amazing is how everything works together—fruit juices soaking upward, crunchy cake on top, and fabulous toppings just like the ice cream shop favorite. Unlike fussy desserts that need perfect technique, this one's super forgiving while still packing incredible taste in every bite.
I whipped this cake up for a backyard cookout when I needed something quick but impressive. My kitchen smelled absolutely amazing with sweet fruit and buttery cake baking together. What really got me was watching everyone take their first bite—that awesome moment when they recognized those childhood flavors in a totally different way. Even my brother-in-law, who usually skips dessert completely, came back for another helping and asked how to make it.
Juicy Foundation
- Very ripe bananas: They get super sweet while baking and add wonderful caramel flavors throughout. Go for ones with dark spots for the best sweetness.
- Fresh strawberries: They bring bright pops of color and just enough tang to balance the sweetness. Pick completely red berries without any white parts for maximum flavor.
- Crushed pineapple with juice: Adds a tropical kick and needed moisture to the base. Its natural acidity helps cut through the richness around it.
- Yellow cake mix: Creates that perfect golden, buttery top without any fuss or measuring. The powder works its magic during baking.
- Butter: Turns the dry mix into a delicious crunchy layer with amazing flavor. Go with unsalted to keep control of the saltiness.
- Heavy whipping cream: Adds a soft, fluffy quality to the dense cake with mild milky sweetness. Its light texture works beautifully against the fruity bottom.
Assembly Wonder
- Fruit Foundation:
- Cut ripe bananas into coin-shaped pieces and lay them across your buttered baking dish in one layer. They'll turn extra sweet while baking, making little pockets of deliciousness throughout. Dump the whole can of pineapple with all its juice right on top and spread it around so every spoonful gets that tropical tang that makes this dessert so good.
- Berry Brilliance:
- Remove the tops from fresh strawberries, slice them up, and toss them all over the pineapple. They'll get softer in the oven but still keep their shape, adding bright red spots and jammy goodness all through the cake. Their slight sourness perfectly balances out the sweeter stuff in the dessert.
- Cake Creation:
- Gently scatter the dry cake mix across all the fruit, making an even layer of powder. Don't stir it in – keeping everything separate is key to getting those amazing texture differences that make dump cakes so special. The powder will change completely during baking as it soaks up juice from the fruit below.
- Butter Blessing:
- Drizzle melted butter all across the cake mix, working carefully to hit as much of it as possible. Any spots you miss will stay powdery instead of turning into that yummy crispy top. Take your time here – this step creates that magical contrast between the soft, juicy fruit and the crunchy, buttery topping.
- Golden Perfection:
- Slide your cake into the hot oven and bake until the top turns a beautiful golden color and the edges bubble with fruit juices. When you see this happening, you'll know the cake mix has soaked up all the butter and formed a crust while the fruits below have released their sweet juices and merged 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 picked the traditional banana split, and he'd share little bits of each section with me. When I made this dump cake version for the first time, I called him right away to tell him about it. Even at 92 years old, he tried making it himself and told me it was "better than the original" – which was huge coming from someone who really knows his banana splits!
Tasty Combinations
This flexible dessert works great in all kinds of settings from casual to fancy. For family dinners, serve it a little warm with some vanilla ice cream on top 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 over for a more elegant look. During summer get-togethers, set it out next to a coffee station with different flavored creamers that go well with the sweet fruitiness.
Fun Variations
Switch up this simple recipe by trying different fruit mixtures based on what's in season. Try swapping the strawberries for blueberries or blackberries to get deeper flavors and beautiful color changes. If you're into coconut, sprinkle some shredded coconut over the cake mix before adding the butter to add tropical hints throughout. Make a chocolate lover's version by using chocolate cake mix instead of yellow and throwing in some chocolate chips between the fruit and cake for amazing melty spots.
Storage Tips
Keep any leftover cake in the fridge with a cover on it where it'll stay good for about four days, though it changes a bit as it gets cold. The cake part becomes more like pudding while the fruit flavors get stronger, making it just as tasty but a little different. Warm up single servings in the microwave for 20-30 seconds if you want that just-baked texture back, or eat it cold straight from the fridge for a cool summer treat. If you need to plan ahead, put everything together except the whipped cream up to a day early, stick it in the fridge, then bake it right before you're ready to serve.
After making dump cakes for years, I've learned how incredibly flexible and mistake-proof they really are. This banana split version has become my go-to dish for potlucks, with friends and family requesting it at every gathering. There's something truly special about turning simple ingredients into a dessert that brings so much happiness and nostalgia. The mix of warm, fruity bottom with cool, creamy toppings hits that perfect sweet spot of temperatures and textures that keeps everyone sneaking back for just one more helping.

Frequently Asked Questions
- → Can I use frozen fruits for this dish?
- Sure! Thawed and drained frozen strawberries work well. But stick with fresh bananas since frozen ones get too mushy. Fresh toppings give the best results too.
- → What if I'm missing some fruit?
- No worries—this dish is flexible! Try adjusting with what you have. For instance, you can skip strawberries or swap them with blueberries, raspberries, or cherries.
- → Can I prepare this dessert ahead?
- Bake the base a day in advance and leave it sealed at room temperature. Add whipped cream and toppings close to serving time so the dish looks great and bananas stay fresh.
- → How will I know when it's fully baked?
- Look for a golden top with bubbling edges from the fruit below. If the top browns too soon but isn't done, cover it loosely with foil to balance baking.
- → Is there a way to make it dairy-free?
- Absolutely! Go for a plant-based butter or coconut oil, use a non-dairy cake mix, and top things off with coconut whipped cream instead.
