Make a crowd-pleasing Banana Split Dump Cake with just a few pantry staples in under an hour! It’s filled with the sweet flavors of pineapple, strawberries, bananas, and nuts, then topped with whipped cream and chocolate syrup for a warm, gooey treat.
I’ve been making this Banana Split Dump Cake on repeat all summer! It takes all the classic flavors of a classic banana split and turns them into a warm, gooey, sweet, buttery dump cake.
As most dump cakes are, it’s incredibly simple to make. You just layer everything in a pan, no mixing bowls or fancy steps needed, and bake it until golden and bubbly. Served warm with lots of toppings, it always disappears fast!
It just may be my favorite dessert to serve to a crowd, especially one that includes kids. Their favorite part is adding all of their favorite toppings, of course. Between the rainbow sprinkles and the chocolate sauce, a fun time is had by all.
“I love a classic banana split and I love a good dump cake recipe, so this one was kind of a no-brainer for me! I was able to make it with my 3 month old strapped to my chest and my 2 year old running around my feet. It was so quick and easy and we had a total blast adding lots of toppings!” — Haley, busy mom of two and passionate home cook and baker.
Key Ingredient Notes
Find the full printable recipe with specific measurements below.
- Strawberry Pie Filling: You can swap it for cherry pie filling or raspberry if you prefer a different berry flavor. Avoid using fresh strawberries here as they won’t hold up the same way during baking.
- Crushed Pineapple: No need to drain it! The juice is essential to the cake’s texture and will keep the cake gooey and moist.
- Cake Mix: You can use white cake mix or yellow cake mix. White cake mix lets the fruit flavors shine, while yellow gives a slightly richer, buttery taste. Use any brand you like best.
- Chopped Nuts: Walnuts, pecans, or even peanuts will work – use what you have or what you prefer.
Tips For Making Banana Split Dump Cake
Gather ’round for a slice of sunshine! This easy banana split cake is pretty much fail-proof. Still, here are just a few little tips and tricks to make sure you get the very best results every time. Visit the printable recipe card for the full directions!
Once you layer everything in the baking dish, do NOT stir it. To have the right texture, all the ingredients need to be in even layers. Trust the process!
Use a spoon to gently spread the dry cake mix on top. Then spread the butter slices evenly across the top of the cake mix so it bakes up golden and crispy in every bite.

Don’t worry if the cake jiggles a bit when you pull it from the oven. That’s normal and means the fruity base is still bubbling. Let it cool for about 15 minutes before serving so it can set up just enough without losing that warm, gooey goodness.
I love serving this cake warm with whipped cream and a scoop of vanilla ice cream. Then whatever toppings you’re feeling… We usually go for fresh sliced bananas and a drizzle of chocolate syrup.
If you’re feeding a crowd, set up a little “sundae bar” with toppings like caramel sauce, chopped nuts, maraschino cherries, and rainbow sprinkles—everyone can dress up their slice just how they like it.
Variations to Try
Some people like to add shredded coconut on top before baking, which toasts up beautifully and adds great texture. Or, add the sweetened shredded coconut and also use macadamia nuts or chopped almonds for a tropical vibe.
And if you want a stronger banana flavor, try adding banana slices under the cake mix layer or stirring in banana pudding mix before baking.
Storing and Reheating
Have any leftovers? You’re in luck – this cake keeps and reheats like a dream!
Wait for your leftover cake to fully cool to room temperature prior to storing in an airtight container in the fridge. Properly stored, it’ll stay fresh for up to 3 days.
Reheat individual portions in the microwave for 30 seconds at a time until warmed all the way through.
