Banana Split Dump Cake

The kitchen counter was a disaster zone of bowls and half opened packages when my youngest announced she wanted banana splits for her birthday. It was pouring rain, completely miserable ice cream weather, and I was already tired from a long week at work. That's when I remembered hearing about dump cakes from my aunt and decided to throw caution to the wind with this banana split version. The way the house smelled while it baked made everyone forget about the rain entirely.

I brought this to a neighborhood potluck last summer and watched three different people ask for the recipe before they even finished their first serving. My friend Sarah, who claims she never eats dessert, went back for seconds and took some home for her kids the next day. There is something about the combination of warm fruit and that golden buttery topping that makes people feel instantly at home.

Ingredients

• 2 large ripe bananas: Look for bananas with plenty of brown spots, they mash beautifully and release more natural sweetness into the layers below
• 1 can (540 ml/19 oz) crushed pineapple: Drain it really well, excess liquid makes the cake soggy, and press it gently with a fork
• 1 cup maraschino cherries: These provide that classic pop of color and tart sweetness that cuts through the rich butter topping
• 1/2 cup mini chocolate chips: Mini chips distribute evenly so every bite has chocolate, regular chips sink too much
• 1 box (about 425 g/15 oz) yellow cake mix: The dry mix creates this incredible crumbly topping that bakes into something between cake and cobbler
• 1/2 cup (115 g) unsalted butter, melted: Pour this slowly and evenly so every bit of cake mix gets coated for that golden crunch
• 1 cup chopped walnuts or pecans: Add these if you want that satisfying crunch, toast them lightly for extra depth
• Whipped cream and chocolate syrup: These are not optional, they complete the banana split experience

Instructions

Prep your oven and pan:

Heat your oven to 175°C (350°F) and give a 9x13 inch baking dish a generous coating of butter or cooking spray

Layer the bananas:

Arrange your banana slices in a single even layer, overlapping slightly, covering the entire bottom of the dish

Add the pineapple:

Spread the drained crushed pineapple over the bananas, creating a fruit foundation that will bubble up beautifully

Scatter the cherries and chocolate:

Distribute the halved maraschino cherries and mini chocolate chips evenly, no need to be perfect, just aim for coverage

Sprinkle the nuts if using:

This is the moment to add walnuts or pecans if you want that extra layer of texture and nutty flavor

Top with cake mix:

Pour the dry cake mix over everything, using your hands to break up any clumps and create an even blanket

Drizzle the butter:

Pour melted butter slowly back and forth across the cake mix, letting it soak in completely without stirring

Bake until golden:

Bake for 40 to 45 minutes until the top is deep golden brown and you see the fruit filling bubbling up around the edges

Serve it up:

Let it rest for about 10 minutes, then serve warm with whipped cream, chocolate syrup, and maybe an extra cherry

This has become my go to when someone needs comfort food or a celebration treat. Last month my neighbor was going through a tough time, and I showed up with this still warm from the oven. She told me later it was exactly what she needed, which is exactly what food should be sometimes.

Making It Your Own

Once you have the basic technique down, this dessert welcomes all kinds of variations. I have swapped the yellow cake mix for chocolate when craving something darker, and chocolate covered cherries were born that day in my kitchen.

Serving Suggestions

Warm is best, right out of the oven, but leftovers reheat beautifully in the microwave for thirty seconds. A scoop of vanilla ice cream melting into the warm fruit creates the most incredible sauce you will ever taste.

Storage Tips

This keeps surprisingly well in the refrigerator for up to three days, covered tightly with foil. The topping does soften slightly but the flavors actually deepen and meld together even more.

• Reheat individual portions in the microwave, not the whole dish
• Freeze unbaked portions for up to two months if you want to prep ahead
• Always bring it to room temperature before baking if you have refrigerated the unbaked version

There is something deeply satisfying about turning simple ingredients into a dessert that makes people close their eyes and smile. That is what keeps me coming back to this recipe again and again.

Recipe Questions & Answers

→ Can I prepare banana split dump cake ahead of time?

Assemble the layers up to 8 hours before baking, cover tightly, and refrigerate. Add the melted butter just before popping in the oven. Leftovers keep well for 2-3 days when refrigerated in an airtight container.

→ What's the best way to serve this dessert?

Warm servings shine brightest. Let the baked cake rest 10-15 minutes before scooping. Top generously with whipped cream, chocolate syrup, and a maraschino cherry. A scoop of vanilla ice cream creates the perfect temperature contrast.

→ Can I use fresh pineapple instead of canned?

Fresh pineapple works beautifully, though you'll need about 2 cups diced. Lightly drain excess moisture to prevent a soggy bottom. Canned crushed pineapple provides consistent sweetness and texture throughout the year.

→ Why shouldn't I stir the butter into the cake mix?

Leaving the butter undisturbed creates that signature dump cake texture—golden, crispy patches mixed with tender, cakey areas. Stirring would result in a more uniform batter, losing the delightful crust variation that makes this dessert special.

→ How do I know when it's finished baking?

The surface should be golden brown with darker crispy patches. You'll see bubbly fruit filling peeking through spots in the topping. A toothpick inserted into the crusted areas should come out clean or with moist crumbs, never wet batter.

→ Can I make this without cherries?

Absolutely. Replace maraschino cherries with fresh strawberries, raspberries, or additional banana slices. The fruit component balances the sweet cake mix and buttery topping, so any favorite berry or tropical fruit works wonderfully.
