Turn your favorite banana split treat into a cozy, crowd-pleasing dessert you can enjoy anytime. With layers of cake, fruit, and tasty toppings, this sweet bake lets you skip the usual race against melting ice cream and just dig in.
I whipped this up for my niece’s birthday because she wanted both cake and a banana split. When everyone saw you could have both in one dish, it became a family must-have from that day on.
Irresistible Ingredients
- Chopped nuts: Sprinkle for crunch so you’ve got some bite amid the soft fruit and fluffy cake
- Heavy whipping cream: Whip it up yourself for a super light, billowy topping
- Chocolate syrup: Gives that childhood-favorite drizzle, can’t skip it
- Yellow cake mix: Turns into a golden, tender topping you just can’t mess up
- Fresh strawberries: Give a bold pop of color and tang that balances the sweet stuff
- Unsalted butter: Melts over the top for a crust that’s both rich and crumbly
- Crushed pineapple: Juicy and sweet with a little tang, plus it makes your cake extra moist
- Ripe bananas: Look for lots of spots—they taste the sweetest and make for the best flavor
Delightful How-To Guide
- Showstopper Topping Time:
- Plop on dollops of whipped cream, toss on more fruit, and sprinkle with nuts. Make it pretty with slices of banana and a few strawberry halves. Finish with chocolate syrup—can’t miss this step, that’s what makes it feel just like the classic parlor treat.
- Let It Settle:
- Give your bake a little rest time, during which you can whip the cream until soft and fluffy. Resting helps all that bubbly fruit turn nice and jammy under the cakey top.
- Straight to the Oven:
- Slide your pan into the oven and bake until golden brown and the edges are bubbling away with fruity goodness. It’s fine if fruit peeks through. Your kitchen will smell like vanilla and sweet, toasted fruit.
- Let the Butter Flow:
- Pour melted butter all over and cover everything as much as possible—make sure no dry bits are left. Butter is the secret to a crisp golden topping and helps the cake form up.
- Add That Cake Layer:
- Evenly dust the dry cake mix on top so every bit of fruit is covered. No need to stir it in! Just spread and you’re done with this part.
- Fruit Explosion:
- Next up, spread pineapple over the bananas and add strawberries on top. Don’t forget to squeeze out extra juice from the pineapple, so your cake isn’t soggy. These fruits give that classic split flavor combo and keep things tangy.
- Sliced Banana Base:
- Lay banana slices in a single layer across the bottom of your dish. The heat will bring out their natural caramel notes and makes a sweet base for the whole dessert.

Don’t sleep on the pineapple here—it’s the real magic-maker. The banana is expected, but the pineapple keeps everything moist and delivers a burst of flavor that takes things up a notch. My grandma would always double the pineapple because it was her secret for the best bakes at church events.
Plan Ahead Tricks
Get this dessert ready a day early if you want. Bake it up, stash in the fridge covered, and just save your whipped cream and sprinkles for right before serving. The flavors actually get better the next day, so it’s a lifesaver when you’re busy and need to prep ahead.

Try It Different Ways
Bananas and pineapple are always around, but you can swap out the fruit to match the season. In summer, try peaches or blueberries instead of strawberries. Slice up apples and dust the cake mix with cinnamon for a fall feel. In winter, throw in some cranberries and orange zest—perfect for those chilly days when you want something special.
Easy Swaps for All Diets
You can make changes here to fit whatever food needs your guests might have. Going gluten-free? Pick your favorite gluten-free cake mix. Need dairy-free? Grab non-dairy butter and use coconut whipped cream. This dessert is flexible so nobody’s left out and everyone can dig in to that banana split goodness.
Serving Ideas
Honestly, tastes great just as is, but when it’s warm and you drop some vanilla ice cream on top—wow, next level! Hot-cold, soft-crisp, all together. Or bring it to a brunch at room temp, served with coffee for a treat. Want to be a little fancy? Add a touch of mint and a squiggle of chocolate when you plate it up. Suddenly it looks restaurant-worthy.
