  • Cook Time: 45
  • Total Time: 45
  • Yield: 24 brownies 1x
  • Category: Dessert


  • 8 tablespoons (1 stick) unsalted butter, plus more for pan
  • 6 ounces bittersweet chocolate, chopped
  • 2 cups all-purpose flour
  • 1 teaspoon baking powder
  • 1/2 teaspoon salt
  • 1 1/2 cups sugar
  • 4 large eggs
  • 1 tablespoon pure vanilla extract
  • 1 1/4 cups pumpkin puree (canned is ok)
  • 1/4 cup vegetable oil
  • 1 teaspoon ground cinnamon
  • 1/4 teaspoon ground nutmeg


  1. Preheat oven to 350 degrees. Butter a 9-inch square baking pan or dish. Line bottom of pan with parchment paper; butter lining.
  2. Melt chocolate and butter in a heatproof bowl set over a pan of simmering water, stirring occasionally until smooth.
  3. Whisk together flour, baking powder, and salt in a large bowl; set aside. Put sugar, eggs, and vanilla in the bowl of an electric mixer fitted with the paddle attachment; beat until fluffy and well combined, 3 to 5 minutes. Beat in flour mixture.
  4. Divide batter between two medium bowls (about 2 cups per bowl). Stir chocolate mixture into one bowl. In other bowl, stir in pumpkin, oil, cinnamon, and nutmeg. Transfer half of chocolate batter to prepared pan smoothing top with a rubber spatula. Top with half of pumpkin batter. Repeat to make one more chocolate layer and one more pumpkin layer. Work quickly so batters don’t set.
  5. With a small spatula or a table knife, gently swirl the two batters to create a marbled effect.
  6. Bake until set, 40 to 45 minutes. Let cool in pan on a wire rack. Cut into 16 squares.


I made this recipe in a larger 9×13 pan in the photos. I multiplied the ingredients by 1 1/2. The brownies in a 9×9 pan are taller and more gooey. If you stretch the recipe to a 9×13 pan as is, check baking time 10 minutes sooner because the batter will be thinner.

Boxed brownies:

I’ve received a lot of requests for a boxed brownie adaptation. If you want to use a boxed brownie mix, follow the directions in the box, then come to the recipe on Step 4 and begin by dividing the batter. Bake in the pan size suggested in the box mix and follow baking directions on the box.

    Hi Laura!

    I made these tonight (on my “to-do” list forever), and baked in a 9×9 for 45 minutes. My husband checked them for me at 45 min at 350°, and pulled them out since I told him they would be gooey by your recipe. I’m super bummed that they are way undercooked in the center. Any idea what I did wrong besides not cooking them long enough? Also, what speed do you beat the sugar, eggs, and vanilla? I guessed and used a medium speed.


    1. Laura Fuentes says:

      Oh no! I’m not sure what happened but these should form up definitely by 45min. I beat my butter, sugar, eggs.. Etc on high but that should t matter. Do you have an oven thermometer ? Sounds like the oven could be running cold (just a 25deg diff will slow down cooking). So sorry!

      1. Sabrina says:

        I just realized that I used aluminum free baking powder. Do you think that may have made a difference?

        1. Laura Fuentes says:

          It should not.

    All year long, wow those look good!!

    1. Laura Fuentes says:

      Thanks Matt! my pictures look almost as mouthwatering as yours. almost.

  3. Marc says:

    Thank You for Martha Stewart’s recipe, it was great.

  4. Emily says:

    Can I do this using a box of brownies and a whole can of pumpkin? What should I do differently? My prep time is limited depending on how long my baby naps but these look so yummy!

    1. Laura Fuentes says:

      I imagine you can use boxed brownie mix and just follow the directions starting at step 4.

  5. Bessie N says:

    Per Martha Stewart’s recipe, she also had 1/4 tsp of cayenne and the sugar was increased by 1/4 cup. Wouldn’t that make a difference in taste?

    1. Laura Fuentes says:

      Hi Bessie, as mentioned, I adapted it from her recipe. I did not add cayenne and I reduced the sugar. Mine came out great.
