Pumpkin Oatmeal Dump Cake is a cozy fall dessert featuring a creamy spiced pumpkin base topped with a buttery oat and cake mix crust. It’s effortless to make and perfect for holiday gatherings or simple autumn cravings.

  • Total Time: 55–65 minutes
  • Yield: 12 servings

Ingredients

  • 1 can (15 oz) pumpkin puree
  • 1 can (12 oz) evaporated milk
  • ¾ cup sugar
  • 3 large eggs
  • 1 teaspoon cinnamon
  • ½ teaspoon nutmeg
  • 1 box yellow cake mix
  • 1 ½ cups rolled oats
  • ½ cup butter, melted

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, sugar, eggs, cinnamon, and nutmeg until smooth.
  3. Pour pumpkin mixture into the baking dish and spread evenly.
  4. Sprinkle dry yellow cake mix evenly over the top — do not stir.
  5. Evenly layer rolled oats over the cake mix.
  6. Drizzle melted butter across the top, covering as much of the surface as possible.
  7. Bake for 45–55 minutes or until the top is golden and the center is set.
  8. Let cool slightly before serving.

Notes

  • Add chopped pecans or walnuts for extra crunch.
  • Use spice cake mix for deeper autumn flavor.
  • Enhance spice with a pinch of ginger or cloves.
  • Use gluten-free cake mix and oats for a gluten-free version.
  • Skip nuts for a nut-free version; oats still give crunch.
