This Easy Pumpkin Dump Cake with Pecan Streusel is a simple, dump-and-bake dessert that combines a soft, spiced pumpkin layer with a buttery, crunchy pecan streusel topping. It’s perfect for fall gatherings and always a crowd-pleaser.

Ingredients

Scale
  • 1 can (15 oz) pumpkin puree (not pumpkin pie filling)
  • 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
  • ½ cup chopped pecans
  • ¼ cup packed brown sugar (light or dark)
  • ½ cup unsalted butter, melted

Instructions

  1. Preheat oven to 350°F (175°C). Grease a 9×13-inch baking dish with butter or non-stick spray.
  2. Make the pumpkin layer: In a large bowl, whisk together pumpkin puree, evaporated milk, eggs, granulated sugar, vanilla extract, pumpkin pie spice, and salt until smooth.
  3. Pour the pumpkin mixture into the prepared baking dish and spread evenly.
  4. Make the streusel topping: In a small bowl, combine yellow cake mix, chopped pecans, and brown sugar. Stir with a fork to break up clumps. Pour melted butter over the top and stir until the mixture looks like wet, clumpy sand.
  5. Sprinkle the pecan streusel evenly over the pumpkin layer. Do not press down.
  6. Bake for 45-50 minutes, until the top is golden brown and the edges are bubbly. A toothpick inserted into the center should come out mostly clean.
  7. Let the cake cool on a wire rack for at least 20 minutes before serving.

Notes

For a dairy-free version, swap evaporated milk for full-fat coconut milk and use plant-based butter. For gluten-free, use a gluten-free yellow cake mix. Pecans can be replaced with walnuts or pepitas. If you don’t have pumpkin pie spice, mix 1½ teaspoons cinnamon, ½ teaspoon nutmeg, ¼ teaspoon ginger, and a pinch of cloves. Let the cake cool for at least 20 minutes before serving to allow it to set properly.
