Ingredients

  • 1 can (15 oz) pumpkin puree
  • 1 can (12 oz) evaporated milk
  • 3 large eggs
  • 1 cup granulated sugar
  • 1/2 cup brown sugar
  • 1 teaspoon cinnamon
  • 1/2 teaspoon nutmeg
  • 1/2 teaspoon ginger
  • 1/4 teaspoon cloves
  • 1 box yellow cake mix
  • 1 cup rolled oats
  • 1/2 cup chopped pecans (optional)
  • 1/2 cup melted butter

Instructions

  1. Preheat oven to 350°F (175°C) and grease a 9×13-inch baking dish.
  2. In a large bowl, whisk together pumpkin puree, evaporated milk, eggs, granulated sugar, brown sugar, cinnamon, nutmeg, ginger, and cloves until smooth.
  3. Pour the pumpkin mixture into the prepared baking dish and spread evenly.
  4. Sprinkle the dry yellow cake mix evenly over the pumpkin layer—do not mix.
  5. Top with rolled oats and chopped pecans (if using).
  6. Drizzle melted butter evenly over the entire surface, making sure most dry areas are moistened.
  7. Bake for 50–60 minutes, or until the top is golden brown and the edges are bubbling.
  8. Cool for at least 20 minutes before serving. Serve warm with whipped cream or vanilla ice cream if desired.

Notes

  • Use spice cake mix instead of yellow for a stronger pumpkin spice flavor.
  • Add crushed graham crackers or more oats for extra crunch.
  • Substitute coconut milk and vegan butter for a dairy-free version.
  • Replace pecans with walnuts or pumpkin seeds for variation.
  • Store leftovers in the fridge up to 4 days or freeze up to 2 months.
