Ingredients
  

  • 1 (29-oz) can pure pumpkin purée
  • 1 (12-oz) can evaporated milk
  • 3 large eggs
  • 1 cup light brown sugar
  • 1 teaspoon ground cinnamon
  • 1/2 teaspoon pumpkin spice
  • 1 teaspoon vanilla extract
  • 1 (15.25-oz) box yellow cake mix
  • 1 1/2 sticks unsalted butter, melted (12 tablespoons )
  • 1 cup coarsely chopped pecans

Instructions
 

  • Prep: Heat oven to 350°F. Grease a 9×13-inch baking dish.
  • Mix pumpkin layer: In a large bowl, whisk together pumpkin purée, evaporated milk, eggs, brown sugar, cinnamon, pumpkin spice, and vanilla. Pour into prepared dish and spread evenly.
  • Add cake layer: Sprinkle yellow cake mix evenly over pumpkin mixture, do not stir! Pour melted butter evenly over cake mix, a few dry spots are fine. Evenly scatter chopped pecans on top.
  • Bake: Bake for 55–60 minutes, or until top is golden and set. Start checking after 45 minutes, loosely cover with foil if top gets too dark.
  • Cool: Allow cake to cool fully before slicing to serve. Chill in fridge for 2-3 hours for neatest slicing.

Notes

Ingredient notes
  • Pumpkin purée: Use pure pumpkin purée, NOT pie filling.
  • Evaporated milk: Swap with heavy cream or half-and-half if needed.
  • Cake mix: Spice cake mix adds extra fall flavor.
  • Butter: Unsalted is best! Stick margarine is fine to use.
  • Pecans: Replace with walnuts or leave out for nut-free.
Recipe tips
  • Butter drizzle: Pour slowly to cover as much cake mix as possible.
  • No stirring: Leave the layers as-is for the perfect crust.
  • Cool completely: Chill in the fridge for 2–3 hours for clean slices.
Storage tips
  • Room temperature: Serve the same day; cover for a few hours.
  • Refrigerator: Store covered for up to 4 days.
