pumpkin-chocolate swirl brownies

by Amy on 6 October 2011

if you’re anything like me, as soon as fall rolls around, you’re wanting to eat pumpkin. lots + lots of pumpkin in all sorts of delicious forms. i absolutely love pumpkin in desserts, so when i came across this recipe for pumpkin + chocolate swirl brownies, i knew i had to try ’em. luckily, i already had everything i needed to make them in the house, so i hopped in the kitchen + started baking.

these brownies? they are amazing. the flavor combination of chocolate + pumpkin is simple, yet utterly satisfying. the creamy pumpkin blends perfectly with the rich, decadent chocolate, creating a delicious, moist, gooey bar of deliciousness. they make for a perfect dessert after a comfort-food meal full of autumn flavors. + it doesn’t hurt that they are gorgeous, both with the lovely pumpkin + cocoa colors as well as the delicate marble appearance on the top of ’em. in short? these brownies rock + if you love pumpkin + chocolate like i do, you gotta try ’em!

pumpkin-chocolate swirl brownies

makes 16 brownies, adapted from martha stewart


8 tablespoons (1 stick) unsalted butter, plus more for pan
6 ounces bittersweet chocolate, chopped
2 cups all-purpose flour
1 teaspoon baking powder
1/4 teaspoon cayenne pepper
1/2 teaspoon salt
1 3/4 cups sugar
4 large eggs
1 tablespoon pure vanilla extract
1 1/4 cups solid-pack pumpkin
1/4 cup vegetable oil
1 teaspoon ground cinnamon
1/4 teaspoon ground nutmeg
1/2 cup chopped hazelnuts or other nuts


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 + butter in a heatproof bowl set over a pan of simmering water, stirring occasionally until smooth.

whisk together flour, baking powder, cayenne, + salt in a large bowl; set aside. put sugar, eggs, + vanilla in the bowl of an electric mixer fitted with the paddle attachment; beat until fluffy + 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, + 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 + 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. sprinkle with nuts if using them.

bake until set, 40-45 minutes. let cool in pan on a wire rack. cut into 16 squares.

Wow. Great combination of flavors. I don’t think I’ve ever had them combined. I love the pumpkin recipes in the fall (only 2nd to apple, of course).

i absolutely love chocolate + pumpkin combined. i used to eat pumpkin chocolate chip muffins from my local coffee shop all the time in college + that’s when i first discovered the combination. it’s such a delicious combo!

5 Ashley @ Kitchen Meets Girl October 6, 2011 at 11:01 am

Hmmm…is it a coincidence that I *also* have all of the ingredients to make these? Pumpkin is by far my favorite fall flavor. These are a must-make!

6 amy October 6, 2011 at 11:10 am

these look truly divine. The only thing that could make brownies even better would be the addition of pumpkin :) All this desserty goodness is making me want to get in the kitchen!

10 amy October 6, 2011 at 1:47 pm

thanks, rachel! the cooler fall weather always makes me want to get bakin’, especially with pumpkin. definitely one of my favorite flavors of the season!

So I’m home unusually early today after a doc check-up where my Physician mentioned the health benefits of pumpkin. And what do you know, I just happen to have all of those ingredients on hand. I wonder what I’ll be baking for dessert tonight…..

These looks so pretty & delicious Amy. I wonder what they would taste like with dark chocolate.

12 amy October 6, 2011 at 2:50 pm

ha, what a fun coincidence! i like the way your doctor thinks. =) these would taste *amazing* with dark chocolate – you should definitely give that adaptation a try! great idea.

These look amazing!! Is it awful that I haven’t cooked much with pumpkin before? I am so excited to try some new desserts this fall and I am loving this pumpkin and chocolate combo!!

14 amy October 6, 2011 at 4:50 pm

thanks so much, breana! it’s not awful at all that you haven’t cooked with pumpkin before. although consider yourself warned – cooking/baking with pumpkin is addictive, especially in the fall. =)

15 Mommyof2Girlz/StephD October 6, 2011 at 7:28 pm

Yay more pumpkin recipes and this looks delicious!!

16 amy October 6, 2011 at 7:35 pm

20 amy October 7, 2011 at 7:09 am

me, too – it’s one of my favorite fall flavor combinations. i had only tried it in muffin + cupcake form before this recipe – now i know that it’s great in brownies, too!

Amy these brownies are tugging at every “GET FIT” resolution I’ve made for this Fall! Shame on you for posting!

(you obviously know my weakness: chocolate + pumpkin (well anything plus pumpkin) = no inhibitions.)

These may have just made the weekend cooking list…

24 amy October 7, 2011 at 2:31 pm

whoops! at least pumpkin has some great health benefits, as does chocolate. =) now, the butter … admittedly not so much. let me know how they turn out for you if you make ’em. have a fabulous weekend!

Mmm…pumpkin love. These look amazing! I’m intrigued by the pepper….Can’t wait to try a gluten-free version :-)

34 amy October 10, 2011 at 5:30 pm

i was intrigued by the pepper, too – it adds a tiny kick + really brings out the flavor of both the chocolate + the pumpkin. delicious!
