There’s something magical about a recipe that requires minimal prep, just a handful of ingredients, and bakes into a dessert that feels like sunshine in a bowl. The Mango Dump Cake is exactly that kind of dessert. With bright, juicy mangoes and a crisp, buttery topping, this cake will quickly become a favorite for anyone who loves easy, crowd-pleasing treats. This recipe might have “dump” in its name, but don’t let that fool you—each bite offers layers of rich, fruity flavor and golden, crumbly topping that feel far more sophisticated than the effort it takes to create it.

The Inspiration Behind the Mango Dump Cake
My love for mangoes goes way back to childhood summer visits with my grandparents. We’d spend hours in their backyard, picking ripe mangoes straight from the tree. I’d come back sticky and blissfully happy, cheeks flushed from the heat and hands filled with nature’s candy. The Mango Dump Cake brings me back to those days with every single bite. The juicy mangoes nestled beneath a buttery cake topping remind me of simpler times, while the warmth of the baked fruit captures the feeling of summer, no matter what time of year it is. This cake is a wonderful reminder that sometimes the best recipes are the ones that let the ingredients speak for themselves.
Key Ingredients That Make This Mango Dump Cake Special

- Fresh or Canned Mangoes: Mangoes are the heart of this dessert, and both fresh and canned options work beautifully. Fresh mangoes lend a slight tang and enhanced natural sweetness, while canned mangoes offer convenience and a smoother texture. If you’re using fresh, choose ones that are just ripe for the best flavor. If you go with canned, be sure to drain them well to keep your cake from getting too moist.
- Yellow Cake Mix: This cake mix is the secret behind the effortless crust in a dump cake. It provides a perfect foundation for that golden, crumbly layer on top, while subtly complementing the mangoes’ sweetness. With the right amount of moisture from the butter, the cake mix transforms from powder into a soft, crispy topping.
- Butter: Melted butter does double duty in this recipe, adding flavor and aiding in forming the crisp topping. Each drizzle melds with the cake mix, creating a buttery layer that is both crispy and tender. The golden color that develops while baking is enough to make anyone’s mouth water!
- Optional Additions – Cinnamon and Sugar: A touch of cinnamon gives this dessert a gentle warmth, perfect for cooler weather or for those who like a little spice with their mango. Adding sugar can boost the sweetness, but it’s entirely optional. You could also try a sprinkle of brown sugar for a hint of caramel flavor.
How to Make the Mango Dump Cake
One of the joys of a dump cake is how easy it is to put together. Unlike traditional cakes that require careful mixing, layering, and folding, a dump cake invites you to simply “dump” each ingredient into the baking dish and let the oven work its magic. Here’s how it all comes together:
- Preparation: Preheat your oven to 350°F (175°C) and lightly grease a 9×13-inch baking dish. This ensures an even bake and makes for easy serving later.
- Setting the Fruit Layer: After prepping the mangoes—either by peeling and dicing fresh ones or draining canned ones—spread them evenly across the bottom of the baking dish. For a slightly thicker fruit base, sprinkle a small amount of the dry cake mix over the bottom before adding the fruit. This little trick helps hold the fruit juices, creating a nice base for the cake to rest on.
- Adding the Cake Mix and Butter: Sprinkle the cake mix evenly over the mangoes. It may look like a lot of powder at first, but resist the urge to stir—it’s important for the “dump” process that each layer remains undisturbed. Then, drizzle the melted butter over the entire dish. Try to cover as much of the surface as possible so the topping crisps up evenly. For a warm, cozy flavor, sprinkle cinnamon or a touch of sugar over the top.
- Baking and Serving: Bake the cake for 40-45 minutes, or until the topping is golden and crisp, and the fruit is bubbling at the edges. Allow it to cool slightly before scooping out portions into bowls. A scoop of vanilla ice cream or a dollop of whipped cream takes this already delightful cake to the next level.

Tips for the Perfect Mango Dump Cake
- Choosing Mangoes: If you’re using fresh mangoes, look for fruit that gives slightly when pressed—these will be juicy and sweet. Avoid mangoes that are too firm, as they may not soften as much during baking.
- Butter Coverage: When drizzling butter, try to cover as much surface area as possible. The butter is what activates the cake mix, transforming it into that delicious topping.
- Serving Fresh: This cake is best enjoyed warm out of the oven. If making it in advance, warm it slightly before serving to bring back that fresh-baked texture.

Serving Suggestions
To make this mango dump cake extra special, serve it warm with a scoop of vanilla ice cream or a generous spoonful of whipped cream. The cold, creamy topping melts into the warm cake, creating a perfect balance of textures and flavors. Another lovely option is to sprinkle some toasted coconut flakes or a few fresh mint leaves on top for added color and a hint of tropical flair.

Emma, can you use frozen mangoes in your recipe? Thank you.
Hi Anne, yes frozen mangoes work just fine! Just make sure to thaw and drain them well first so the cake doesn’t turn out too soggy. I’ve used them when fresh mango wasn’t in season and it still came out delicious.
