This mango dump cake has become my go-to dessert when I need something impressive with minimal effort. The combination of juicy mangoes and buttery cake topping creates a dessert that tastes like you spent hours in the kitchen when it really only takes minutes to prepare.

I first made this on a busy weeknight when unexpected guests were coming over. They were so impressed they asked for the recipe before leaving and now it's become my signature dessert for potlucks and family gatherings.

Ingredients

  • Canned diced mangoes: Provide the perfect sweet base and ensure consistent results year round
  • Yellow cake mix: Creates that perfect golden crust without any measuring of dry ingredients
  • Unsalted butter: Adds richness and helps the cake mix transform into a crispy golden topping
  • Optional vanilla ice cream: Makes the warm cake even more indulgent

Step-by-Step Instructions

Prepare Your Baking Dish:
Preheat your oven to 350°F and lightly grease a 9×13 inch baking dish. Make sure to coat the sides as well as the bottom to prevent sticking. The light coating of grease will also give your cake a beautiful golden edge.
Create The Mango Layer:
Drain your canned mangoes thoroughly removing as much liquid as possible to avoid a soggy cake. Spread the diced mangoes in an even layer across the bottom of your prepared baking dish. Try to distribute them uniformly for consistent flavor in every bite.
Add The Cake Layer:
Sprinkle the dry cake mix evenly over the mangoes ensuring complete coverage. Take care not to compress the cake mix just let it sit lightly on top of the fruit. Any gaps or heavy spots will affect how the cake bakes.
Finish With Butter:
Drizzle the melted butter over the entire surface of the cake mix trying to cover as much area as possible. The butter will help the cake mix brown and create a delicious crust. If you notice dry spots consider using a touch more butter.
Bake To Golden Perfection:
Place in the preheated oven and bake for 45 to 50 minutes until the top is golden brown and you can see the mango filling bubbling around the edges. The contrast between the caramelized top and juicy mangoes is what makes this dessert special.

My favorite part of this recipe is how the butter creates these incredible crispy edges that contrast with the soft fruity center. My husband always claims the corner pieces which have the most of this delicious texture contrast.

Making It Fresh

When mangoes are in season I love to use fresh fruit instead of canned. Simply peel and dice about 3 cups of ripe mangoes tossing them with a tablespoon of sugar before adding to the baking dish. Fresh mangoes bring a brighter flavor and wonderful aroma that fills your kitchen while baking.

Storage Tips

This dump cake stays delicious for several days. Keep it covered at room temperature for up to 2 days or refrigerate for up to 5 days. The cake portion will soften slightly when stored but many people prefer this texture. To refresh reheat individual portions in the microwave for about 20 seconds.

Serving Suggestions

While this cake is delicious on its own it reaches new heights when served warm with vanilla ice cream. The contrast between the hot cake and cold ice cream creates a delightful sensory experience. For brunches I sometimes serve it with a dollop of Greek yogurt which adds a tangy contrast to the sweet mangoes.
