Banana Split Dump Cake

The summer our old air conditioner gave up the ghost, my kitchen felt more like a tropical greenhouse than a cooking space. Too hot to even contemplate turning on the oven for anything elaborate, I still needed to bring something to my sister's backyard barbecue that afternoon. This dump cake became my saving grace—simple enough that I wasn't sweating over complicated steps, but impressive enough that everyone assumed I'd spent hours on it.

I remember bringing this to a potluck at work and watching my normally reserved coworker Greg go back for thirds. He kept trying to figure out what made the topping so crunchy while still being tender underneath. The best part was telling him it was just cake mix and butter—his face was absolutely priceless.

Ingredients

• 3 large ripe bananas, sliced: Look for bananas with plenty of brown spots—they're sweeter and will caramelize beautifully in the oven
• 1 can (20 oz / 565 g) crushed pineapple, drained: Really press out that excess liquid or you'll end up with a soggy bottom layer
• 1 jar (10 oz / 280 g) maraschino cherries, drained and halved: These little pops of color make the whole dish feel festive and bright
• 1/2 cup (100 g) granulated sugar: Helps all those fruit juices bubble up into something syrupy and wonderful
• 1/2 cup (90 g) semisweet chocolate chips: Scatter them like treasure—they'll melt into gooey pockets throughout the cake
• 1 box (15.25 oz / 432 g) yellow cake mix: No need to prepare it according to the package directions, just pour it straight from the box
• 3/4 cup (170 g) unsalted butter, melted: The magic that transforms dry cake mix into something golden and irresistible

Instructions

Get your oven ready:

Preheat to 350°F (175°C) and give a 9x13-inch baking dish a quick coating of cooking spray

Build the fruit foundation:

Arrange those banana slices like you're creating a mosaic, then spread pineapple over them and tuck cherries throughout

Add the sweet touches:

Sprinkle sugar evenly across the fruit, then scatter chocolate chips like you're hiding little chocolate surprises

Create the crust:

Pour the dry cake mix over everything—don't mix it, just let it blanket the fruit in an even layer

The butter moment:

Drizzle melted butter slowly back and forth until most of that dry cake mix gets kissed with golden moisture

Bake until golden:

Let it bake 40 to 45 minutes until the top turns a gorgeous golden brown and you see bubbling around the edges

Practice patience:

Let it rest at least 15 minutes so those fruit juices have time to thicken up slightly

My daughter now requests this for every single birthday celebration. Watching her carefully arrange the cherries in perfect rows while I drizzle the butter has become one of those sweet kitchen rituals I'll treasure forever.

Make It Your Own

Sometimes I swap the chocolate chips for white chocolate when I want something extra decadent. During winter holidays, I've added a sprinkle of cinnamon to the sugar layer—it gives the whole dish this cozy warmth that feels absolutely perfect for cold weather gatherings.

Serving Suggestions

While it's fantastic straight from the dish, a scoop of vanilla bean ice cream melting into those warm fruit layers creates something transcendent. For summer parties, I like to set up a little toppings bar so everyone can customize their portion with whipped cream, crushed nuts, or even a drizzle of salted caramel.

Storage and Make-Ahead Tips

This actually reheats beautifully the next day—just pop individual portions in the microwave for about 30 seconds. You can assemble everything up to the butter drizzle step, cover tightly, and refrigerate for up to 8 hours before baking.

• Let refrigerated dumps come to room temperature for about 20 minutes before baking
• Add a few extra minutes to the baking time if it's cold from the fridge
• The fruit will release more liquid if it sits too long before baking, so don't assemble more than 8 hours ahead

There's something deeply satisfying about a dessert that looks impressive but comes together with such minimal effort. This is the kind of recipe that makes people think you're some sort of kitchen wizard, when really you just know how to layer delicious things and let the oven do its magic.

Recipe FAQs

→ Can I make this dessert ahead of time?

Yes, you can assemble the layers up to 24 hours in advance and store covered in the refrigerator. Add the melted butter just before baking. Leftovers keep well for 3-4 days when refrigerated in an airtight container.

→ What's the best way to serve this?

Warm is ideal—the fruit layer becomes wonderfully gooey and the buttery topping stays crisp. Let it rest for at least 15 minutes after baking so the layers set slightly. Top with whipped cream, chopped nuts, or ice cream for the full banana split experience.

→ Can I substitute the yellow cake mix?

You can use white cake mix, butter pecan cake mix, or even a homemade equivalent. Chocolate cake mix would work but would make it very rich. Just ensure you're using a standard 15-ounce box for proper proportions.

→ Do I need to drain the pineapple?

Yes, draining the crushed pineapple is important. Too much liquid will make the dessert soggy and prevent the cake mix from baking into a proper crumble. Use the drained juice in smoothies or other dishes.

→ Can I use fresh cherries instead of maraschino?

Fresh cherries work but will be more tart. Maraschino cherries provide the classic bright color and sweetness that balances the bananas and pineapple. If using fresh, pit and halve them, and consider adding an extra tablespoon of sugar.

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

The top should be deep golden brown with no dry powdery spots remaining. The edges should be bubbling with fruit juices, and a toothpick inserted into the center should come out clean or with moist crumbs but not raw batter.
