Fudgy chocolate chip pumpkin swirl brownies combine the best of both worlds in one dessert. Fudgy brownie batter is swirled with a perfectly spiced pumpkin mixture in this dessert bar recipe perfect for fall.
So I’ve done it. Pumpkin. I was going to hold off until next month to share these chocolate chip pumpkin swirl brownies but I’m impatient and couldn’t wait. I blame it on Mother Nature for gracing us with an extended respite from the typical hot and humid August weather (NOT that I’m complaining…), which has caused my brain to speed up and think about all things fall.
Plus these brownies are SO good, it felt wrong to keep them all to myself, you know? I’m not selfish like that. 😉
Ever end up with a small amount of pumpkin puree left after you’ve cracked open a can for a recipe? That’s what inspired me to make these pumpkin swirl brownies. I was left with one-third of a cup of pumpkin puree after updating the pictures on an old recipe post, and wanted to put it to good use.
I also had a craving for brownies (which isn’t anything out of the ordinary, really) so what better way to satisfy both “problems”, if you will, at once.
The brownie portion comes directly from my one bowl small-batch brownies recipe. I bake those brownies in a 9″ x 5″ loaf pan, but opted for a 9″ x 9″ baking dish here as I knew adding pumpkin batter to the top would make up for the height lost by using a wider pan.
One of the many things I love about the brownie portion here is that it’s FUDGY. So fudgy. It provides the perfect base for the pumpkin to be added on top and is substantial for slicing. Is there any dessert not enhanced by a brownie layer? I’m not sure there is.
Because the brownie layer is fairly thin, I used a cookie scoop to disperse portions of the pumpkin batter over top for swirling. This way you don’t have to worry about trying to smooth out a perfectly even pumpkin layer.
The swirling is meant to be imperfect, which is right up my alley when it comes to decorating desserts. Lord knows I’m not a gifted cake or cookie decorator — icing this rainbow cookie cake is probably the extent that I can go. “Rustic” is a lot more my speed. 🙂
The pumpkin batter is spiced with pumpkin pie spice and softer and less dense than the fudgy brownie bottom, so you’ll get a variety of textures and flavors in each bite. You can use a store-bought pumpkin pie spice mix if you like, or you can make your own using this recipe if you’ve got the spices on hand already. There’s also a bonus recipe for apple pie spice there, too, if we’re going to commit to going all in on fall.
Tools used:
- Cookie scoop for portioning out the pumpkin batter over top of the brownie layer. Of course you don’t have to use one here if you don’t want to, but the sweeper arm helps make things easier and less messy. I use my cookie scoops for everything from serving ice cream to forming perfectly even meatballs.
- 9″ x 9″ square baking pan – alternatively you could also use an 8″ x 8″ baking pan if that’s what you have, but these pumpkin swirl brownies may require an extra few minutes of baking as they’d be a bit taller.

Fudgy Chocolate Chip Pumpkin Swirl Brownies
Ingredients
Brownie Layer:
- 4 tbsp unsalted butter
- 3/4 cup semi-sweet chocolate chips, divided
- 1/2 cup granulated sugar
- 1 egg, at room temperature
- 1 tsp vanilla extract
- 1/4 cup all-purpose flour
- 1/2 tsp espresso powder (optional)
- Pinch of salt
Pumpkin Layer:
- 2/3 cup all-purpose flour
- 1 tsp pumpkin pie spice
- 1/4 tsp baking soda
- 1/4 tsp salt
- 6 tbsp unsalted butter, at room temperature
- 6 tbsp packed brown sugar
- 3/4 tsp vanilla extract
- 1/3 cup pumpkin puree
- 1/4 cup semi-sweet chocolate chips
Instructions
- Preheat oven to 350°F. Line a 9" x 9" cake pan with parchment paper, leaving enough excess parchment along two opposite sides of the pan so that you can easily pull out the cooled brownies for slicing later on.
For the brownie layer:
- Add 4 tbsp butter and 1/2 cup of the chocolate chips to a large microwave-safe bowl and microwave in 20 seconds intervals, stirring well after each increment, until melted and smooth.
- Add 1/2 cup granulated sugar, egg, and 1 tsp vanilla extract and mix well.
- Add 1/4 cup flour, espresso powder (if using), and pinch of salt and mix until combined. The batter will have a bit of a 'shiny' look to it. Stir in remaining 1/4 cup chocolate chips.
- Pour brownie batter into the prepared pan and spread with a spatula so it's in an even layer. Set aside.
For the pumpkin layer:
- Whisk together 2/3 cup flour, pumpkin pie spice, baking soda, and salt in a mixing bowl.
- Add room temperature butter and brown sugar to a separate mixing bowl and cream together using a hand or stand mixer on medium speed. Add vanilla extract and pumpkin puree and mix until well combined.
- Add the dry ingredients to the bowl with the wet ingredients and mix until just combined on low speed. Fold in chocolate chips.
- Add dollops of the pumpkin mixture over top of the brownie layer, using a spoon or a cookie scoop. Run a knife through the dollops to lightly swirl the pumpkin and brownie mixture together. Continue until all dollops are swirled and the surface is level throughout.
- Bake for 30 minutes, or until a toothpick inserted into the center of the pan comes out clean or mostly clean, with only a few crumbs clinging to it. Let the pumpkin swirl brownies cool in the pan, and then lift out by the parchment and slice.
