Turn a banana split into a cozy, crowd-pleasing treat you can scoop straight from the pan. Layers of juicy fruit, soft cake, and fun toppings mean every bite tastes like pure joy, minus the race to finish before the ice cream melts.
The first time I tried this was for my niece, who couldn't decide between cake and banana splits for her birthday. When everyone realized they got both at once, the excitement was real. We've made it for just about every celebration since.
Effortless Ingredients
- Yellow cake mix: This gives you that classic, sunny cake layer without any fuss
- Unsalted butter: Melt some to pour on top — it's what makes the crumbly, golden pieces
- Chopped nuts: That bit of crunch keeps each scoop interesting
- Heavy whipping cream: Whip it up for a cloud-like topping you just can't get from a tub
- Chocolate syrup: Drizzle at the end for that nostalgic sundae vibe
- Fresh strawberries: They brighten the whole dish and add a hint of tartness
- Crushed pineapple: This keeps the bottom nice and juicy with hints of the tropics
- Ripe bananas: Make sure they're spotted and sweet for that real banana flavor
Playful Step-by-Step Guide
- Pile on the Showy Finish:
- Spoon on clouds of whipped cream, a handful of fresh fruit slices, and a rain of nuts. Have fun arranging extra banana slices and some strawberry halves on top. Finish with a generous chocolate drizzle so it really looks just like a banana split in cake form.
- Let It Cool, Then Whip Up the Toppings:
- Set the pan aside for a bit to cool, then whip your cream until it holds soft peaks. As it sits, the fruit underneath will thicken up, making a sweet, jammy layer no one can resist.
- Bake Until Dreamy:
- Tuck it into the oven and bake until the top gets that deep golden brown and the fruit juices start bubbling up around the edges. You'll smell just how amazing it's getting as soon as you open the oven door.
- Butter Goes Last:
- Slowly pour melted butter over the whole thing, trying to cover all the cake mix. Take your time so you don't miss any dry spots—otherwise, there could be powdery patches.
- Cake Mix Magic:
- Dust the entire surface with dry cake mix, making sure everything below gets hidden. Don’t stir! Let the oven do its thing and create a tender cake topping.
- Add the Juicy Layer:
- Scoop those pineapple and strawberry slices on top of the bananas. Be sure you’ve drained the pineapple really well to keep things from getting soggy. The fresh fruit gives you that tangy burst and makes the layers sing.
- The Banana Blanket:
- Lay banana rounds across the bottom of your baking dish—try not to leave any gaps. The bananas turn extra sweet and golden once baked, forming a gooey base.

Pineapple isn’t just a background player here — it keeps everything moist and brings bright, tropical flavors, the kind you don’t expect but love after the first bite. My grandma always put in extra, swearing that’s why hers was always the hit at the church get-togethers.
Make Ahead Tips
You can bake this whole thing ahead and stash it in the fridge overnight if you want to get ahead. Just don’t add the whipped cream or nuts until the last minute so everything stays fresh. Letting the fruit and cake sit together only makes it tastier and easier for busy folks who need to plan ahead.

Tasty Variations
Banana and pineapple work year-round, but feel free to switch it up! Swap in peaches or blueberries in summer for a fresh twist. In the fall, apple slices and a dash of cinnamon taste amazing. Around the holidays, toss in cranberries and some orange zest for something festive and bright—you can really play with it any time of year.
Flexible Options
Easy to tweak for allergies or preferences. Use gluten-free cake mix for gluten-free needs, or sub in a plant-based butter and coconut cream for a dairy-free treat. It’s the kind of dessert everyone can enjoy, even if you need a few swaps.
Serving Ideas
Honestly, this shines on its own, but if you want to go all out, serve it warm with a scoop of ice cream on top. That mix of warm and cold recreates the classic banana split vibes in each bite. For brunch, just serve at room temp with strong coffee. If you want to impress, serve it up in slices with a little mint and a big chocolate swirl for that extra wow.
Common Questions
- → Can I use frozen bananas here?
Yep! Frozen bananas totally work. Just make sure you let them thaw and then drain off any extra liquid before tossing them in.
- → Could I swap out the cake mix for something else?
You sure can! Try vanilla, white, or go all in with chocolate cake mix—just use whatever you like best.
- → How's the best way to keep leftover dump cake?
Just pop leftovers in a sealed container and tuck it in the fridge for up to three days. Warm up a slice in the microwave if you want it toasty again.
- → Can I toss extra toppings on top?
Absolutely, add caramel, colorful sprinkles, or go big with a scoop of ice cream to make it extra awesome.
