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.

Common Questions

→ Is it okay to use frozen bananas in this treat?

Yep, just let them thaw and pour off any extra water that comes out before tossing them in.

→ Can I swap in a different cake mix flavor?

For sure! Go with vanilla, white, or get wild and try chocolate if you're in the mood.

→ What's the best way to keep leftover dump cake fresh?

Pop it in a sealed container and stash it in the fridge. It'll stay good for about three days. Warm up slices in the microwave if you like it cozy.

→ Are other toppings okay on this cake?

Definitely! Try some caramel sauce, colorful sprinkles, or a scoop of ice cream if you want to go all out.

→ Is there something dairy-free I can use for the whipped topping?

Grab a non-dairy option or coconut whipped cream and you're all set—nobody's missing out!

What You'll Need

→ Dump Cake Base

01 1 stick (½ cup) unsalted butter, melted
02 1 box yellow or white cake mix
03 1 cup fresh strawberries, sliced
04 1 can (20 oz) crushed pineapple, drained
05 4 medium ripe bananas, sliced

→ Toppings

06 Chocolate syrup or melted chocolate for drizzling if you want
07 ½ cup chopped pecans or walnuts
08 ½ cup fresh strawberries, halved or sliced
09 1-2 bananas, sliced for topping
10 1 cup heavy whipping cream or 1 tub whipped topping

Step-by-Step Directions

Step 01

As the cake cools off a bit, beat the heavy cream until you get soft peaks, or just grab some whipped topping from the store. Slather or plop that onto the cake. Throw on some banana slices, your strawberries, plus a handful of chopped nuts. Finish up with a good splash of melted chocolate or chocolate syrup if you’re feeling it.

Step 02

Slide your dish into the hot oven. Bake about 40 to 45 minutes, just until the top’s golden and there’s bubbling around the edges. Take it out and hang tight for 15 minutes so it can cool down and hold together.

Step 03

Pour the cake mix dry right over the fruit—don’t stir it at all. Next, pour the melted butter all over that cake mix. Try to get as much of it covered as you can.

Step 04

Fire up your oven to 350°F (that’s 175°C). Grab a 9x13-inch dish and coat it with butter or some non-stick spray. Line the bottom with all your banana slices. Dump the drained pineapple on top. Follow that with those strawberry slices.
