This pumpkin swirl brownies recipe is moist, delicious and a fall staple. My kids love brownies, but in the fall, I take the opportunity to make all things pumpkin.

Pumpkin Brownies
You simply can’t beat brownies. Within five minutes of entering the oven my entire house smells of warm chocolatey bliss…and with the addition of pumpkin in this recipe, it’s fall meets chocolate. So you simply can’t go wrong!
I love to make pumpkin everything. Pumpkin Pancakes, soups, chili, cookies, pumpkin scones…you could say I love the flavor, taste and smell.
Of course, my kids will devour anything brownie. At the slightest hint of the aroma making its way through the house my kids come running and I simply can’t get them into their hands fast enough! Add a tall glass of milk and these pumpkin brownies will turn any ordinary night into something special!
Pumpkin Spice Brownies
This is one of those recipes that just can’t be made one time and then forgotten. Year after year I bring it out, it’s a perfect way to welcome the fall season! Bring this recipe to any fall or holiday party and you’ll be a rockstar.
Getting your kids involved is simple with this recipe. My son loves to mix the chocolate while my daughter likes to take the credit for the pretty swirl.

These tasty pumpkin brownies are perfectly swirled with chocolate and creamy pumpkin to make the perfect Fall dessert!
- Cook Time: 45
- Total Time: 45
- Yield: 24 brownies 1x
- Category: Dessert
Ingredients
- 8 tablespoons (1 stick) unsalted butter, plus more for pan
- 6 ounces bittersweet chocolate, chopped
- 2 cups all-purpose flour
- 1 teaspoon baking powder
- ½ teaspoon salt
- 1 ½ cups sugar
- 4 large eggs
- 1 tablespoon pure vanilla extract
- 1 ¼ cups pumpkin puree (canned is ok)
- ¼ cup vegetable oil
- 1 teaspoon ground cinnamon
- ¼ teaspoon ground nutmeg
Instructions
- Preheat oven to 350 degrees. Butter a 9-inch square baking pan or dish. Line bottom of pan with parchment paper; butter lining.
- Melt chocolate and butter in a heatproof bowl set over a pan of simmering water, stirring occasionally until smooth.
- 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.
- 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.
- With a small spatula or a table knife, gently swirl the two batters to create a marbled effect.
- Bake until set, 40 to 45 minutes. Let cool in pan on a wire rack. Cut into 16 squares.
Notes
I made this recipe in a larger 9×13 pan in the photos. I multiplied the ingredients by 1 ½. 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.
Thanks!

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!
Sabrina
I just realized that I used aluminum free baking powder. Do you think that may have made a difference?
Laura Fuentes
It should not.
Matt
All year long, wow those look good!!
Laura Fuentes
Thanks Matt! my pictures look almost as mouthwatering as yours. almost.
Marc
Thank You for Martha Stewart’s recipe, it was great.
Emily
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!
Laura Fuentes
I imagine you can use boxed brownie mix and just follow the directions starting at step 4.

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?

Laura Fuentes
Hi Bessie, as mentioned, I adapted it from her recipe. I did not add cayenne and I reduced the sugar. Mine came out great.
Angelica
Hi Laura,
Could I blend a pumpkin myself as an alternative for canned puree?
Laura Fuentes
You can, but the result will be thinner in consistency than canned pumpkin. Canned pumpkin is thicker and more concentrated. I haven’t tried it so I cannot advise on the texture.
Christina
I puréed and used my own roasted pumpkin and it came out great! My husband and picky daughter were surprised how good it was with the pumpkin in it! My boys devoured it! Great recipe! Will make again. Thank you!

Laura Fuentes
Thank you for using my recipe, Christina! Thrilled everyone enjoyed it.
Sammy
Hi Laura, I only have a baking tray that measures 11.5 x 8.5 inches. This will make me 12 brownies. What measurements should I go by? If I half those ingredients it doesn’t sound like it will be enough?
Thanks
Laura Fuentes
That pan size will work, your brownies will not be as tall.

I don’t think this recipe adapts easily to using a boxed brownie mix and simply picking up at step 4. The boxed brownie mix is all chocolate versus the non-chocolate half of batter used for the pumpkin swirl in step 4. If using a boxed brownie mix, one would have to omit the first 2 ingredients, use half of the next 6 ingredients to make the non-chocolate batter which is then mixed with the last 4 ingredients for the pumpkin swirl.
