  • 1 cup packed brown sugar

  • 1 12 oz can evaporated milk
  • 2 teaspoons vanilla extract
  • 1 box vanilla cake mix only the cake mix - not the ingredients to make the cake
  • 1 cup chopped pecans
  • ¾ cup unsalted butter


  • Preheat the oven to 350F degrees. Lightly grease a 9x13 inch baking pan.
  • In a large bowl whisk together the pumpkin, eggs, sugar, pumpkin pie spice, evaporated milk and vanilla
  • Pour the mixture into the prepared pan.
  • Sprinkle the cake mix on top so that the pumpkin layer is evenly covered.
  • Sprinkle the chopped pecans on top.
  • Cut the butter into thin slices and place on top of the cake mix doing your best to evenly cover the cake mix. It does not have to be entirely covered.
  • Bake in the preheated oven for 60 minutes or until the top is golden and the middle of the cake no longer wobbles.
  • Cool for at least 15 minutes, then slice and serve.
