This upside-down banana split cake brings your favorite ice cream shop treat into a cozy, shareable baked dessert that turns everyday moments into celebrations. The buildup of fresh fruits, cake layers, and garnishes creates a taste explosion that captures the fun of a banana split without worrying about melting ice cream.
I whipped this up for the first time at my niece's party when she couldn't decide between banana splits and birthday cake. Seeing everyone's surprised faces when they realized they got two treats in one dish instantly turned this into a must-have at family get-togethers.
Ingredients
- Ripe bananas: Go for ones with dark spots for biggest flavor punch and natural sweetness
- Crushed pineapple: Delivers juicy sweetness and keeps everything moist throughout
- Fresh strawberries: Add gorgeous red pops and tangy flavor against the sweet backdrop
- Yellow cake mix: Forms that soft, buttery golden topping everyone loves
- Unsalted butter: Transforms the cake powder into a delicious crumbly crust
- Heavy whipping cream: Beating it yourself gives airiness that nothing from a can will match
- Chopped nuts: Bring that much-needed crunch against all the soft textures
- Chocolate syrup: Completes the nostalgic banana split experience we remember from our younger days
Step-by-Step Instructions
- Create the Fruit Foundation:
- Spread sliced bananas across the bottom of your baking dish. They'll get slightly caramelized during cooking and create a sweet base layer. Try to cover every inch of the pan bottom for the best taste in each serving.
- Layer the Tropical Elements:
- Add well-drained pineapple chunks over bananas then put strawberry slices on top. Make sure you've gotten rid of excess pineapple juice or you'll end up with soggy cake. These fruits work together to cut through sweetness with their natural tang.
- Apply the Dry Cake Layer:
- Dust cake mix powder all over the fruit in an even coating. Don't stir it in. The dump cake magic happens when this dry stuff cooks into a cake top while fruit underneath bubbles into its own sauce.
- Add the Butter Bath:
- Slowly drizzle melted butter all over, trying to hit every bit of dry mix. Any spots missed will stay powdery after baking, so take your time covering everything. The butter helps create that golden, crispy top crust.
- Bake to Golden Perfection:
- Stick it in the oven until the surface turns deep gold and you see fruit juices bubbling at the edges. You might notice fruit peeking through in spots and that's totally fine. Your kitchen will smell amazing with vanilla and sweet fruit scents.
- Cool and Prepare Toppings:
- Let it cool a bit while you whip cream until it forms soft peaks. This cooling time allows the bubbling fruit to settle and thicken into that perfect jammy texture under the cake part.
- Create the Showstopping Finish:
- Pile on fluffy whipped cream, arrange fresh fruit slices, and scatter nuts across the top. Get creative with how you place banana slices and strawberry halves. The final chocolate drizzle lets everyone know right away this is a banana split in cake form.

The crushed pineapple really works magic in this dish. While everyone notices the banana flavor first, it's the pineapple that brings extra moisture and that special tropical twist that makes this more than just another dump cake. My grandma always threw in extra pineapple and claimed that was why her version always disappeared first at church gatherings.
Make Ahead Options
You can put this whole cake together and bake it a full day before you need it. Just keep it in the fridge with a cover, but don't add the whipped cream and final toppings until you're ready to serve. The cake and fruit layers actually taste better after sitting overnight as the flavors mix together, making this perfect for busy people who need to get dessert done early.

Seasonal Variations
You can find bananas and pineapple all year, but you can switch up this cake with whatever fruits are in season. During summer, swap some strawberries for fresh blueberries or peaches. In fall, try thin apple slices with a bit of cinnamon mixed into the cake powder. Winter versions taste great with cranberries and orange zest for holiday meals, so you've got a flexible dessert for any time of year.
Dietary Adaptations
You can easily change this recipe to fit different diet needs. Got gluten concerns? Just grab a gluten-free cake mix instead. Can't do dairy? Use plant butter and whipped coconut cream on top. It's so flexible that you can serve it at parties where guests might have different food restrictions but everyone still gets to enjoy that banana split experience.
Serving Suggestions
This cake tastes amazing by itself but goes to a whole new level when served warm with a scoop of vanilla ice cream on top. The hot-cold combo brings that true banana split feeling to every bite. For morning gatherings, serve it at room temp with coffee. For fancy dinner parties, dish up individual portions with mint leaves and extra chocolate drizzles to make it look restaurant-worthy.
