This easy pumpkin dump cake with yellow cake mix and pecans is the ultimate fall dessert. With only 3 main ingredients and no mixing bowls required, it comes together in under 5 minutes and tastes like you spent all afternoon in the kitchen.

Ingredients

Scale
  • 1 can (15 oz) pumpkin puree
  • 1 can (12 oz) evaporated milk
  • 3 large eggs, room temperature
  • 1 cup granulated sugar
  • 1 teaspoon vanilla extract
  • 2 teaspoons pumpkin pie spice
  • ½ teaspoon salt
  • 1 box (15.25 oz) yellow cake mix
  • 1 cup unsalted butter, melted
  • 1 cup chopped pecans

Instructions

  1. Preheat your oven to 350°F (175°C). Lightly grease a 9×13-inch baking pan with butter or non-stick spray.
  2. In a large bowl, whisk together the pumpkin puree, evaporated milk, eggs, sugar, vanilla extract, pumpkin pie spice, and salt until smooth and well combined.
  3. Pour the pumpkin mixture into the prepared pan and spread it evenly with a spatula. Give the pan a gentle shake to level everything out.
  4. Sprinkle the dry cake mix evenly over the top of the pumpkin layer. Do not stir it in. Make sure every inch of the pumpkin is covered.
  5. Drizzle the melted butter as evenly as possible over the entire surface of the cake mix.
  6. Sprinkle the chopped pecans evenly over the buttered cake mix layer.
  7. Bake for 45-55 minutes, until the top is deep golden brown and the edges are bubbly. The center should be set but still have a slight jiggle.
  8. Let the cake cool for at least 20 minutes before serving. The pumpkin layer needs time to firm up slightly for clean slices.

Notes

Don’t stir the layers together. The magic of a dump cake is that the dry cake mix absorbs the butter and bakes into a crust while the pumpkin layer stays creamy underneath. For a chunkier topping, use cold butter cut into small pieces instead of melted. Toast pecans first for extra flavor. The cake gets better the next day as flavors meld. If using a dark or non-stick pan, reduce oven temperature by 25°F.
