Ingredients
This recipe uses seven main ingredients to capture the flavors of a banana split.
- 3 ripe but firm bananas: Peeled and sliced into rounds. Choose bananas that are sweet but not overly soft.
- 1 can (20 ounces) crushed pineapple, undrained: Adds juicy tropical flavor and moisture.
- 1 can (21 ounces) strawberry pie filling: Provides sweet strawberry flavor and a thick fruit layer.
- 1 box (15.25 ounces) yellow cake mix: Creates the simple cake topping.
- 1/2 cup unsalted butter, melted: Helps moisten the cake mix and encourages golden, buttery patches.
- 1 cup semisweet chocolate chips: Adds the chocolate flavor associated with a classic banana split.
- 1/2 cup chopped walnuts or pecans: Adds crunch and a little nutty flavor. Omit for a nut-free version.
For serving, you can add vanilla ice cream, whipped cream, or chocolate sauce. These are optional toppings and are not included in the seven main ingredients.
How to Make Banana Split Dump Cake
Step 1: Prepare the Oven and Baking Dish
Preheat your oven to 350°F (175°C). Lightly grease a 9-by-13-inch baking dish.
Arrange your ingredients on the counter before beginning so the layers are easy to assemble.
Step 2: Add the Fruit Layers
Spread the undrained crushed pineapple evenly across the bottom of the prepared baking dish.
Arrange the sliced bananas over the pineapple, distributing them as evenly as possible.
Spoon the strawberry pie filling over the bananas and gently spread it into an even layer.
Step 3: Add the Cake Mix
Sprinkle the dry yellow cake mix evenly over the fruit mixture.
Use a spoon to distribute the mix into the corners, but do not stir it into the fruit. Keeping the layers separate helps create the signature dump cake texture.
Step 4: Add the Butter
Drizzle the melted butter as evenly as possible over the dry cake mix.
Try to moisten as much of the surface as you can. Some small dry patches may remain, but evenly distributing the butter helps the topping bake more consistently.
Step 5: Add Chocolate Chips and Nuts
Sprinkle the chocolate chips and chopped walnuts or pecans over the top.
The chocolate melts into delicious pockets throughout the topping, while the nuts add crunch.
Step 6: Bake Until Golden and Bubbly
Bake for approximately 45–55 minutes, until the fruit filling is bubbling around the edges and the cake topping is golden.
If some areas of the cake mix still look dry after 35–40 minutes, check whether they need a little more moisture from the surrounding fruit or melted butter. Continue baking until the topping is cooked through.
If the top begins to brown too quickly, loosely cover the dish with foil for the remainder of the baking time.
Step 7: Cool Slightly and Serve
Remove the baking dish from the oven and let the cake rest for 15–20 minutes.
The fruit filling will be extremely hot straight from the oven, so allow it to cool slightly before serving.
Spoon the warm cake into bowls and top with vanilla ice cream or whipped cream for a banana split-inspired dessert.
Tips for the Best Banana Split Dump Cake
Use ripe but firm bananas. Very soft bananas can become mushy during baking. Bananas with a few brown spots are ideal.
Do not mix the layers. A dump cake relies on the fruit, dry cake mix, and butter baking together without being stirred into a traditional batter.
Distribute the butter carefully. Uneven butter coverage can leave dry patches in the topping. A spoon or small measuring cup helps distribute it more evenly.
Let the cake rest before serving. A short cooling period allows the fruit juices to settle and makes serving easier.
Serve it warm. The combination of warm fruit, chocolate, and cold vanilla ice cream is especially delicious.
Easy Banana Split Dump Cake Variations
Chocolate Banana Split Dump Cake
Replace the yellow cake mix with chocolate cake mix for a richer chocolate flavor.
Cherry Banana Split Dump Cake
Replace the strawberry pie filling with cherry pie filling for another classic ice cream shop flavor combination.
Extra Chocolate Version
Add a handful of chocolate chunks along with the chocolate chips for extra chocolate pockets.
Coconut Banana Split Cake
Sprinkle 1/2 cup shredded coconut over the fruit before adding the cake mix. This adds a tropical flavor that pairs beautifully with pineapple.
Nut-Free Banana Split Cake
Simply leave out the chopped nuts. The cake will still have plenty of texture from the fruit and chocolate.

How to Store Banana Split Dump Cake
Refrigerator: Because this cake contains moist fruit and sliced bananas, refrigerate leftovers within 2 hours. Store in an airtight container or cover the baking dish tightly and use within 3–4 days.
Reheating: Warm individual portions in the microwave until heated through. For a larger portion, cover the dish loosely with foil and warm in a 325°F (165°C) oven.
Freezing: Freezing is possible, but the bananas and fruit filling may become softer after thawing. For best quality, freeze portions in airtight, freezer-safe containers and use within 2 months.
Thaw frozen portions in the refrigerator before reheating.
Frequently Asked Questions
Can I make Banana Split Dump Cake ahead of time?
Yes. You can bake it ahead and refrigerate it once cooled. Reheat portions before serving, or serve chilled if you prefer a firmer fruit dessert.
For the freshest banana flavor and best topping texture, it is especially good when baked the day you plan to serve it.
Do I need to prepare the cake mix first?
No. Sprinkle the dry cake mix directly over the fruit. Do not prepare it according to the box instructions unless you are intentionally adapting the recipe.
Why does my dump cake have dry patches?
The melted butter may not have reached every part of the cake mix, or the fruit may not have provided enough moisture in some areas. Spread the butter evenly and make sure the fruit layers cover the bottom of the dish.
Can I use fresh strawberries instead of pie filling?
Fresh strawberries can be used, but they do not have the same thickened sweetness or moisture as strawberry pie filling. The finished cake may be less sweet and may require a different fruit preparation.
Can I use fresh pineapple?
Canned crushed pineapple is convenient because it provides both fruit and juice. Fresh pineapple has a different moisture content, so substituting it may affect the texture.
Can I make this without nuts?
Absolutely. Omit the walnuts or pecans for a nut-free version, and check the labels of your cake mix and chocolate chips if you are accommodating an allergy.
