This Banana Split Dump Cake turns that famous ice cream treat into a warm, cozy dessert featuring sweet caramelized bananas, tangy pineapple, and plump strawberries under a crisp, golden topping. What makes it special is how it all comes together - fruit juices soak upward, the top gets wonderfully crunchy, and those classic sundae flavors shine through. Unlike fancier desserts that demand perfection, this easy creation welcomes a casual approach while still delivering amazing taste with every bite.
The first time I whipped this up was for a backyard get-together when I needed something fast but unforgettable. My kitchen smelled absolutely amazing with sweet fruit and buttery cake scents floating through the air. The best part was watching everyone take their first bites - that wonderful 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 me how to make it.
Juicy Foundation
- Extra ripe bananas: They get even sweeter when baked, adding caramel-like flavor throughout. Go for ones with dark spots for the best sweetness.
- Ripe strawberries: They add pretty color and a bit of tartness to balance the sweetness. Pick completely red berries for the tastiest results.
- Canned pineapple with juice: Brings a hint of the tropics and needed moisture to the bottom layer. Its zesty flavor cuts through the richness of everything else.
- Box of yellow cake mix: Forms that perfect buttery, golden top without any fuss or measuring. The powder transforms like magic as it bakes.
- Butter: Turns the cake mix into a delicious crumbly crust with rich taste. Go with unsalted so you can control the flavor.
- Heavy cream: Adds a soft, fluffy element to the dense cake and a gentle milky sweetness. Its light texture works beautifully against the fruit bottom.
Building Bliss
- Bottom Layer:
- Cut your ripe bananas into equal-sized coins and spread them across your buttered baking dish. They'll turn deliciously sweet and soft during cooking, creating little pockets of caramelized goodness throughout. Dump the whole can of pineapple with all its juice right on top, spreading it out so every mouthful gets that tropical zip that makes this dessert so special.
- Strawberry Splash:
- Trim and slice your strawberries before scattering them over the pineapple. They'll get tender but keep their shape while baking, adding bright pops of color and jammy sweetness. Their slight tanginess perfectly balances the other sweeter ingredients.
- Mix Layer:
- Gently scatter the dry cake mix powder over all the fruit, making sure it forms an even layer. Don't stir it in - keeping everything separate is what creates those amazing texture differences that make dump cakes so good. The powder will work its magic during baking as it soaks up the bubbling fruit juices.
- Butter Topping:
- Drizzle melted butter all over the cake mix, taking care to cover as much as possible. Any dry spots won't turn into that yummy crispy top. Take your time here - this step creates that wonderful contrast between the soft, juicy fruit and the crisp, buttery crust.
- Bake to Beauty:
- Slide your creation into the hot oven and bake until the top turns a lovely golden color and fruit juices bubble around the edges. These visual clues tell you the cake mix has soaked up the butter and formed a crust while the fruits below have released their juices and merged together.

I've always loved anything with banana split flavors because my grandpa would buy me ice cream every weekend after we went to church. He always picked the traditional banana split and let me steal little bites from each section. When I first baked this dump cake version, I immediately phoned him with the recipe. At 92 years old, he made it by himself and told me it was "better than the original sundae" - which was huge coming from someone who knew his banana splits!
Tasty Combos
This flexible dessert works great in all kinds of settings. For family night, serve it a bit warm with a scoop of vanilla ice cream that slowly melts into all the nooks and crannies. When you've got company, dish it into pretty individual bowls topped with fresh whipped cream and a thin stream of chocolate sauce for extra wow factor. During summer parties, put it next to a coffee station with different flavored creamers that play off the sweet fruity notes.
Fun Variations
Switch up this basic recipe by trying different fruit mixtures based on what's in season. Try swapping strawberries for blueberries or blackberries to get deeper flavors and stunning color changes. If you're into coconut, toss some shredded flakes over the cake mix before adding butter for a tropical twist throughout. Make a chocolate lover's dream by using chocolate cake mix instead of yellow and tucking some chocolate chips between the fruit and cake layers for amazing melty surprises.
Storage Smarts
Keep any leftover dump cake in the fridge with a cover on it for up to four days, though you'll notice the texture changes a bit as it sits. The cake part gets more pudding-like while the fruit flavors grow stronger, making it different but just as tasty. Warm up single servings in the microwave for about half a minute if you want that just-baked feel, or eat it cold from the fridge for a cool summer treat. If you need to plan ahead, put everything together except the cream up to 24 hours early, keep it in the fridge, then bake it right before you need it.
After countless dump cakes over the years, I've learned to love how flexible and mistake-proof they really are. This banana split version has become my go-to dish that friends and family ask for at every gathering. There's something truly special about taking simple ingredients and creating a dessert that brings so much happiness and memories. The mix of warm, fruity bottom with cool, creamy toppings hits that perfect sweet spot of temperatures and textures that has everyone reaching for just a little bit more.

Frequently Asked Questions
- → Can frozen fruits work here?
- Definitely! You’ll want to thaw and drain frozen strawberries first. Fresh bananas are best since frozen ones can get too mushy. Use fresh toppings for a vibrant look and better texture.
- → What if I’m missing some fruits?
- No sweat! This dish is adaptable. Try replacing strawberries with cherries or raspberries, or go with just bananas and pineapple. You’ll still end up with a tasty dessert!
- → Can I prep this ahead of time?
- Sure can! Bake the base the day before and keep it covered on the counter. Add whipped cream and fruit toppings just before serving so the bananas stay looking fresh.
- → How do I know it’s cooked?
- It’s ready when the top looks golden and no longer wet. You might see some bubbly fruit edges. If it’s browning too fast, loosely cover the dish with foil to avoid overdoing the crust.
- → How do I make it dairy-free?
- Easy switch-ups! Opt for dairy-free cake mix, coconut oil instead of butter, and swap regular whipped cream for coconut whipped cream. Just double-check the cake mix ingredients.
