There are some puddings that instantly transport you back in time, and for me, the classic banana split is one of them. The combination of sweet banana, sharp pineapple, juicy strawberries, and rich chocolate, all crowned with a scoop of vanilla ice cream, is pure nostalgia. We wanted to capture that wonderful experience in a warm, baked dessert that could be shared easily around the dinner table. The result is this Banana Split Dump Cake, a fantastically straightforward fruit cake that delivers all those familiar flavours in a bubbling, golden-brown bake.

This is my go-to recipe when I need something impressive that doesn’t demand hours in the kitchen. The beauty of a dump cake lies in its method; you simply layer the ingredients in a dish without any mixing. The fruit creates a jammy, delicious base, while a box of yellow cake mix and some cold butter magically transform into a buttery, slightly crisp topping that’s utterly moreish. It’s the kind of bake that fills the house with an incredible aroma, drawing everyone to the kitchen to ask what’s for dessert.

This banana split cake works wonderfully for a casual family get-together, a potluck, or just a comforting Sunday pudding. It has the heart of a home-baked fruit crumble but with the unmistakable character of its ice cream parlour inspiration, from the chunks of sweet banana to the melted chocolate chips scattered over the top. If you enjoy desserts that are big on flavour but low on fuss, you will absolutely adore this.

Recipe Overview

This Banana Split Dump Cake layers classic sundae fruits—pineapple, strawberries, and bananas—under a simple, buttery cake topping. As it bakes, the fruit juices bubble up, mingling with the cake mix and butter to create a soft, spoonable dessert with a delightfully crisp crust. I’ve tested this with both tinned and fresh fruit, and find tinned pineapple in juice gives the most consistent, flavourful base without becoming too watery.

Why You’ll Love This Banana Split Dump Cake

• Genuine Flavour: This isn’t just a generic fruit bake. You get the distinct tangy sweetness from the crushed pineapple, the bright notes of strawberry, and the creamy, mellow flavour of ripe bananas in every single spoonful. The melted chocolate and toasted pecans perfectly mimic the classic sundae toppings.
• Ready in Under 75 Minutes: With only 10 minutes of hands-on prep, the oven does all the hard work. The entire dessert comes together from start to finish in just over an hour, making it ideal for a last-minute pudding.
• Flexible Recipe: You can easily adapt this to your liking. Swap the pecans for walnuts or almonds, use a different flavour of cake mix (a chocolate one is fantastic!), or add a handful of shredded coconut for a tropical twist.
• Great for Family Gatherings: Because it’s made in one large dish and serves a good number of people, this banana split cake is brilliant for feeding a family or taking to a friend’s house. It transports well and can be served warm or at room temperature.

Ingredients You’ll Need

For this recipe, we rely on a few quality pantry staples. Using a good quality vanilla cake mix is key—I often use Betty Crocker’s Super Moist Yellow Cake Mix as it creates a lovely, tender topping. Make sure your bananas are ripe but still firm, so they hold their shape during baking. The full measurements are in the recipe card below.

• 1 tin (approx. 560g) crushed pineapple in juice, undrained
• 450g fresh or frozen strawberries, hulled and sliced
• 3 large ripe bananas, sliced into 1cm rounds
• 1 box (approx. 430g) yellow or vanilla cake mix
• 170g cold unsalted butter, cut into small cubes
• 100g pecans, roughly chopped
• 100g milk or dark chocolate chips
• 2 tablespoons demerara sugar (optional, for extra crunch)
• A maraschino cherry for each serving (optional)

Marcus’s Tip: Ensure your butter is very cold. I cut mine into cubes and pop it back in the fridge while I prepare the fruit. Cold butter melts more slowly in the oven, creating a much better, crispier, and more evenly baked topping.

How to Make Banana Split Dump Cake

The process for this fruit cake is wonderfully straightforward. The most important rule is not to stir anything! The magic happens when the layers bake on their own, so trust the process and let the oven do the work.

1. Preheat and Prepare: First things first, preheat your oven to 180°C (160°C fan). Lightly grease a 9×13 inch (23×33 cm) baking dish with a little butter or a neutral oil.
2. Layer the Pineapple: Pour the entire tin of crushed pineapple, including the juice, into the prepared dish. Use a spatula to spread it into an even layer across the bottom. This liquid is essential for baking the cake topping properly.
3. Add the Strawberries and Bananas: Scatter the sliced strawberries evenly over the pineapple. Next, arrange the sliced bananas in a single layer over the strawberries.
4. The “Dump” Step: Now for the key part. Open your box of yellow cake mix and sprinkle the dry powder evenly over the fruit. Try to cover all the fruit right to the edges of the dish. Do not stir it in!
5. Dot with Butter: Take your cold, cubed butter and distribute the pieces evenly all over the surface of the dry cake mix. What works best for me is to space them out by about an inch. This ensures the entire topping gets moisture and bakes into a golden crust.
6. Add Toppings: Sprinkle the chopped pecans and chocolate chips over the top of the butter and cake mix. For an extra crunchy finish, I like to add a light dusting of demerara sugar at this stage.
7. Bake Until Golden: Place the dish in the preheated oven and bake for 50-60 minutes. You’ll know it’s ready when the fruit layer is bubbling vigorously at the edges and the topping is a deep golden brown.
8. Rest and Serve: Carefully remove the dish from the oven and let it cool on a wire rack for at least 15-20 minutes. This allows the fruity layer to set up slightly. Serve warm, topped with a scoop of vanilla ice cream and a maraschino cherry.

Tips From My Kitchen

• Temperature Control: Ovens can vary. If you find the top is browning too quickly before the fruit is bubbling, loosely cover the dish with a piece of foil for the last 15-20 minutes of baking time.
• The Secret Step: I learned that a light press with the back of a spoon after sprinkling the cake mix helps settle it slightly, preventing dry pockets. Don’t press hard, just a gentle pat to even it out before adding the butter. This helps it absorb the fruit juices more evenly.
• Make-Ahead: While this dessert is best baked fresh, you can prepare the fruit layer (pineapple and strawberries) in the dish up to 4 hours in advance. Keep it covered in the fridge. Add the sliced bananas and toppings just before baking to prevent the bananas from browning.
• Storage: Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. It’s delicious cold, but I prefer to gently reheat individual portions in the microwave for about 30-45 seconds.

Equipment You’ll Need

You don’t need any fancy gadgets for this straightforward baking recipe, just a few kitchen basics.

• 9×13 inch (23×33 cm) ceramic or glass baking dish
• Spatula
• Chopping board and knife
• Measuring cups and spoons

Delicious Variations to Try

Once you’ve mastered the basic recipe, feel free to get creative. This dump cake formula is incredibly forgiving and works with many different flavour combinations.

• Tropical Twist: Swap the strawberries for a tin of mango chunks (drained) and replace the pecans with 100g of toasted shredded coconut. A white cake mix works beautifully here.
• Chocolate Cherry Delight: For a richer, more decadent version, use a tin of cherry pie filling instead of the pineapple and strawberries. Stick with the bananas, but use a chocolate fudge cake mix and dark chocolate chips. It’s a bit like a Black Forest gateau meets a banana split.
• Nut-Free Option: If you need to avoid nuts, simply leave them out. To get that lovely crunch, sprinkle the top with 50g of rolled oats along with the demerara sugar before baking.

What to Serve With Banana Split Dump Cake

This warm fruit cake is a delight on its own, but a simple accompaniment can elevate it further. It’s rich and sweet, so something creamy and cool provides a lovely contrast.

• Vanilla Bean Ice Cream: This is the classic and, in my opinion, the best pairing. The cold, creamy ice cream melts into the warm, bubbly fruit, creating a truly irresistible combination.
• Thick Double Cream: For a simpler, very British approach, a generous dollop of cold double cream is fantastic. Its richness complements the cake without adding extra sweetness. For a similar effect, check out our guide to making a Giant Skillet Cookie Recipe which is also great with cream.
• Crème Fraîche: If you find the dessert a little sweet, the slight tang of crème fraîche or even a good quality Greek yoghurt can provide a wonderful balance to the sugary fruit.
