Ingredients

Scale
  • 1 box (15.25 oz) yellow cake mix
  • 1 cup chopped pecans
  • 1 cup (2 sticks) unsalted butter, melted
  • 1 can (15 oz) pure pumpkin puree
  • 1 can (14 oz) sweetened condensed milk
  • 1 package (3.4 oz) instant vanilla pudding mix
  • 1 teaspoon pumpkin pie spice
  • 1 teaspoon vanilla extract
  • 1 container (8 oz) frozen whipped topping, thawed

Instructions

  1. Preheat your oven to 350 degrees F. Lightly grease a 9×13 inch baking dish.
  2. In a medium bowl, combine the dry yellow cake mix and chopped pecans. Pour the melted butter over this mixture and stir until it resembles coarse crumbs. Press two-thirds of this mixture evenly into the bottom of the prepared baking dish.
  3. Bake the crust for 10 minutes. Remove from the oven.
  4. While the crust bakes, prepare the pumpkin filling. In a separate bowl, whisk together the pumpkin puree, sweetened condensed milk, instant vanilla pudding mix, pumpkin pie spice, and vanilla extract until smooth.
  5. Pour the pumpkin filling evenly over the partially baked crust.
  6. Sprinkle the remaining one-third of the cake mix and pecan mixture over the pumpkin layer.
  7. Bake for 30 to 35 minutes, or until the topping is golden brown and the filling is set.
  8. Let the cake cool completely on a wire rack.
  9. Once cooled, spread the thawed whipped topping evenly over the top layer. Chill for at least 2 hours before slicing and serving.

Notes

  • For a texture closer to the classic Hawaii-Style Pumpkin Crunch, use a yellow cake mix for the topping, as specified here.
  • You can substitute walnuts for pecans in the topping if desired.
  • This dessert tastes best when fully chilled, which helps the layers set firmly.
