A quick and easy tropical dump cake bursting with juicy mango and tangy lime flavors, perfect for summer gatherings and simple desserts.

Ingredients

Scale
  • 3 cups fresh mangoes, peeled and diced
  • Juice of 2 limes
  • Zest of 1 lime
  • 1 (20-ounce) can crushed pineapple, drained
  • 1 box (15.25 oz) yellow cake mix
  • 1 cup (2 sticks) unsalted butter, melted
  • 1/2 cup granulated sugar (optional)
  • Pinch of salt
  • Optional: toasted shredded coconut or chopped macadamia nuts for garnish

Instructions

  1. Preheat your oven to 350°F (175°C).
  2. In a large bowl, combine diced mangoes, drained crushed pineapple, fresh lime juice, and lime zest. Toss gently to coat evenly.
  3. Pour the fruit mixture into a 9×13-inch baking dish, spreading it out evenly.
  4. Evenly sprinkle the dry yellow cake mix over the fruit layer.
  5. Melt the butter and slowly drizzle it evenly over the cake mix layer. Spread gently if needed, but do not mix.
  6. Sprinkle granulated sugar and a pinch of salt over the top.
  7. Bake for 45-50 minutes until the top is golden brown and bubbly around the edges.
  8. Let the dump cake rest for 10-15 minutes before serving to thicken the juices.
  9. Optionally, garnish with toasted shredded coconut or chopped macadamia nuts.
  10. Serve warm, optionally with vanilla ice cream or whipped cream.

Notes

If the top browns too quickly but the inside isn’t done, loosely cover with foil for the last 10 minutes of baking. Use fresh lime juice and zest for best flavor. For gluten-free, substitute with gluten-free yellow cake mix. For dairy-free, use vegan butter or coconut oil. Frozen mango chunks can be used if fresh are unavailable but thaw and drain excess juice first.
