This Easy Pumpkin Dump Cake with Yellow Cake Mix and Pecans is a simple, foolproof dessert that combines a spiced, custard-like pumpkin layer with a buttery, crunchy topping. Perfect for fall gatherings, it requires just a few ingredients and minimal effort.

Ingredients

Scale
  • 1 can (15 oz) pumpkin puree
  • 1 can (12 oz) evaporated milk
  • 3 large eggs, room temperature
  • 1 cup granulated sugar
  • 2 teaspoons pumpkin pie spice
  • 1 teaspoon ground cinnamon
  • 1/2 teaspoon salt
  • 1 box (15.25 oz) yellow cake mix
  • 1 cup chopped pecans
  • 3/4 cup unsalted butter, melted

Instructions

  1. Preheat your oven to 350°F (175°C). Place your oven rack in the middle position. Grease a 9×13-inch baking pan lightly with butter or non-stick spray.
  2. In a large mixing bowl, combine the pumpkin puree, evaporated milk, eggs, granulated sugar, pumpkin pie spice, cinnamon, and salt. Whisk until smooth and fully combined.
  3. Pour the pumpkin mixture into the prepared pan and spread evenly with a spatula. Tap the pan gently on the counter to release air bubbles.
  4. Sprinkle the dry cake mix evenly over the pumpkin layer. Do not stir or mix.
  5. Sprinkle the chopped pecans evenly over the cake mix.
  6. Drizzle the melted butter evenly over the entire surface, covering as much of the cake mix as possible.
  7. Bake for 45 to 50 minutes, until the top is golden brown and the edges are bubbling. If the top browns too fast, tent loosely with aluminum foil after 30 minutes.
  8. Let the cake cool for at least 20 minutes before serving. The center will set as it cools.

Notes

The secret is in the butter: drizzle it evenly over the dry cake mix and use the full 3/4 cup. Do not stir the cake mix into the pumpkin layer. Let the cake cool for at least 20 minutes before serving to allow the pumpkin layer to set. For best results, make it a day ahead—the flavors meld and the texture improves.
