This pumpkin cinnamon swirl sourdough loaf is one of the most popular items at my sourdough microbakery, and it always sells out. Pumpkin pie spice goes right into the pumpkin dough, and a ribbon of brown sugar and cinnamon swirls through every slice, so every single bite bursts with warm fall flavor.
Pumpkin Cinnamon Swirl Sourdough
I make this pumpkin cinnamon swirl sourdough for my microbakery, and it’s become one of my most popular items. The first time I released it, people messaged me asking if it would be on the menu again. I was only doing two drops, and once it’s gone, it’s gone!
The next time it went on my menu, people ordered multiples so they could freeze them. They were stocking up for Thanksgiving and Christmas and to enjoy throughout the year, since my menu rotates. It’s also the item that sells out the quickest at my markets.
I tested this recipe multiple times. I’m a big flavor person, and I want every bite of my food to burst with flavor, the kind where you take a bite and say, “Wow, this is so good.” That’s what I wanted for this loaf.
What makes my recipe unique is the pumpkin pie spice in the dough. Most pumpkin swirl breads only put spice in the filling, but pumpkin puree on its own is pretty bland. It needs those warm spices mixed all the way through.
Equipment You’ll Need
To make this pumpkin cinnamon swirl sourdough loaf, you’ll need:
Ingredients for Pumpkin Cinnamon Swirl Sourdough
Exact amounts are also in the recipe card below.
Why I Choose Organic Ingredients
I use organic canned pumpkin in this loaf, and my favorite right now is Nothing But The Truth organic pumpkin. You can also use organic all-purpose flour in place of bread flour. Use whatever brands you can find locally and whatever fits your family and your budget.
For the pumpkin dough:
- 450 g bread flour or organic all-purpose flour – The main flour. Bread flour or organic all-purpose flour both work here.
- 50 g whole wheat flour – Adds a little extra flavor and depth.
- 250 g water – Room temperature. Brings the dough together with the pumpkin.
- 100 g sourdough starter – Active and bubbly, at its peak. Depending on the temperature, mine takes 4 to 8 hours after feeding. I usually feed it the night before when I go to bed, and it’s ready when I wake up.
- 225 g pumpkin puree – Plain canned pumpkin, not pumpkin pie filling. Room temperature. I use organic Nothing But The Truth.
- 10 g salt – For flavor and a stronger dough.
- 1 tablespoon pumpkin pie spice – My secret: it goes right into the dough, not just the filling.
For the cinnamon swirl:
- 50 g brown sugar – Melts into a sweet ribbon through the loaf.
- 6 g cinnamon – Warm cinnamon flavor in every swirl.
Why Pumpkin Pie Spice Goes in the Dough
Most pumpkin swirl sourdough recipes only add spice to the cinnamon filling. When I was testing this recipe, I knew I wanted more. Pumpkin puree on its own is bland, so it needs those warm spices, and the best way to get them into every bite is to mix 1 tablespoon of pumpkin pie spice right into the dough. Then the brown sugar and cinnamon swirl adds a second layer of flavor on top of that. It’s a true pumpkin spice sourdough, inside and out.
I use store-bought pumpkin pie spice because it’s easy to find in any grocery store. If you’d rather make your own, my Homemade Pumpkin Pie Spice recipe is coming soon.
For the pumpkin, I use organic Nothing But The Truth canned pumpkin. If you’d like to make your own, my Homemade Pumpkin Puree guide is coming soon.
Step by Step: How to Make Pumpkin Cinnamon Swirl Sourdough
- In a large glass or stainless steel bowl, mix all of the dough ingredients together: bread flour, whole wheat flour, room-temperature water, active sourdough starter, room-temperature pumpkin puree, salt, and pumpkin pie spice. Mix until no dry flour remains, then cover the bowl.
- Do 3 to 4 rounds of stretch and folds, about 30 minutes apart. To do a stretch and fold, grab one side of the dough, stretch it up, and fold it over the middle. Turn the bowl and repeat on all four sides.
- Cover and let the dough bulk ferment for 5 to 10 hours, depending on the dough temperature. Colder dough takes longer and warmer dough goes faster. A dough at 70°F takes about 8 to 9 hours. If you’re unsure, I’d rather let it go a little more proofed than underproofed, because underproofed bread won’t have that fluffy sourdough texture. It’s ready when it jiggles like Jell-O, has bubbles on the surface, and a gentle poke doesn’t spring right back. (See “Watch Your Dough, Not the Clock” below.)
- Stir the brown sugar and cinnamon together in a small bowl.
- Once the bulk ferment is fully done, turn the dough out onto your counter and gently stretch it into a rectangle. Sprinkle the brown sugar and cinnamon evenly over the top.
- Do a three-fold: fold one side of the rectangle into the middle, then fold the other side over it, like a letter. Then roll the dough up into a log. (Watch my shaping video below.)
- Dust your banneton with regular flour and place the dough in it seam side up. I use an oval banneton because that’s what I have, but a round one works great too. Cover and cold proof in the fridge overnight for 10 to 12 hours.
- Put the Dutch oven, with the lid on, in the oven and preheat it to 450°F along with the oven, about 10 to 15 minutes. I bake this loaf in my cream enameled cast iron Hearth & Hand with Magnolia Dutch oven. I’ve found it’s best not to let the Dutch oven sit in there a long time after it’s preheated. The bottom of the pan gets too hot and burns the bottom of the bread, which makes it hard to cut through, and it isn’t that nice soft, light-brown color.
- Turn the cold loaf out onto a piece of parchment paper and score the top with a bread lame.
- Use the parchment as a sling to lower the loaf into the hot Dutch oven. Place about 3 to 6 ice cubes around the outer rim, between the parchment and the wall of the pot, for steam.
- Bake at 450°F for 30 minutes with the lid on, then remove the lid and bake for 15 more minutes.
- Check the inside with an instant-read thermometer. The loaf is done at 200 to 205°F.
- Move the loaf to a cooling rack and let it cool completely, at least 1 hour, before slicing. Don’t skip this! If you cut it early, the inside will be gummy and not fully set.
Watch Your Dough, Not the Clock: How to Tell Bulk Fermentation Is Done
Don’t just go by the clock. How long bulk fermentation takes depends on your dough temperature, and your dough temperature depends on whether your house is hot or cold. A dough at 70°F takes about 8 to 9 hours, but a warm kitchen can get you there faster and a chilly one can take closer to 10 hours. That’s why I always look at the dough itself instead of setting a timer and walking away.
Here’s what I look for. Fully fermented dough jiggles like Jell-O when you gently shake the bowl, and you’ll see bubbles on the surface. It looks smooth, too. Then I do a quick poke test: push a floured finger into the dough. If it doesn’t bounce back right away, it’s ready. If it springs right back immediately, it needs more time, so keep fermenting and check again.
If you’re on the fence, my recommendation is to lean toward a bit more proofed rather than underproofed. Underproofed bread won’t have that nice, fluffy sourdough texture.
How to Shape a Sourdough Cinnamon Swirl Loaf
The swirl goes in after the bulk ferment is completely finished, during shaping. You stretch the dough into a rectangle, sprinkle the brown sugar and cinnamon over the top, fold it in thirds toward the middle, and then roll it up. Folding before you roll creates extra layers, which is what gives the inside of this loaf that beautiful swirl.
It’s so much easier to see than to explain, so here’s my video of shaping this loaf. Wait until you see the inside!
Tips for Making a Pumpkin Swirl Sourdough Loaf
Use an active, bubbly starter. Your starter should be at its peak when you mix. Depending on the temperature, mine takes 4 to 8 hours after feeding, so I usually feed it the night before when I go to bed, and it’s ready when I wake up. A strong starter gives you a good rise and a fluffy crumb, especially in a dough with pumpkin in it.
Don’t let the Dutch oven sit too long after preheating. I preheat my Dutch oven in the oven while the oven heats up, about 10 to 15 minutes. I’ve found that if it sits in there a long time after that, the bottom of the pan gets too hot and burns the bottom of the bread.
Watch the dough, not just the clock. Bulk fermentation can take anywhere from 5 to 10 hours, depending on your dough temperature and whether your house is hot or cold. A dough at 70°F takes about 8 to 9 hours. Instead of going by time alone, look for the signs: the dough jiggles like Jell-O, has bubbles on the surface, looks smooth, and a gentle poke doesn’t spring right back. If it bounces back immediately, keep fermenting.
When in doubt, give it a little more time. If you’re not sure the bulk ferment is done, lean toward a little more proofed rather than underproofed, so you get that fluffy sourdough texture.
Wait until bulk is fully done to add the swirl. The brown sugar and cinnamon go in during shaping, not during the stretch and folds.
Spread the swirl evenly. Sprinkle the brown sugar and cinnamon all the way across the rectangle so every slice gets some swirl, instead of a pile in one spot.
Roll it snug. A gentle but snug roll keeps the swirl tight and helps the loaf hold its shape in the banneton.
Use a thermometer. The crust can look done before the center is. Check for 200 to 205°F inside before you take it out.
Let it cool at least 1 hour. This is the most important sourdough rule. The inside keeps setting as it cools, so slicing early gives you a gummy center. Wait at least 1 hour, until it’s completely cool.
Mistakes to Avoid with Pumpkin Sourdough Bread
These are common sourdough mistakes that can happen with any swirl loaf, and they’re all easy to avoid.
Cutting it before it’s cooled. A warm loaf is still setting inside. Cut it too soon and the middle will be gummy. Let it cool for at least 1 hour, until completely cool.
Underproofing or overproofing. Don’t end the bulk ferment just because the timer says so. Colder dough needs more time and warmer dough needs less (a 70°F dough takes about 8 to 9 hours). If the dough doesn’t jiggle like Jell-O yet, has few bubbles on the surface, or springs right back when you poke it, it’s under-fermented, so give it more time. Underproofed bread is dense and won’t have that fluffy sourdough texture, so if you have to err, err on the side of a little more proofed. Just don’t let it go so long that the dough turns slack and soupy.
Adding extra filling. It’s tempting to pile on more sugar, but too much filling melts into wet, gummy pockets and can leave gaps in the swirl. Stick with the 50 g brown sugar and 6 g cinnamon.
Sugar leaking out during shaping. Loose sugar at the edges tends to fall out when you fold and roll. Keep the sprinkle even and gently brush any loose sugar back onto the dough before you roll.
A loose roll. A loose roll can leave big gaps between the swirl layers. Roll the dough snugly after the three-fold.
A weak starter. If your starter isn’t active and bubbly, the loaf won’t rise well, and pumpkin dough is heavier than a plain loaf. Feed your starter 4 to 8 hours ahead so it’s at its peak when you mix.
Forgetting that pumpkin adds moisture. Pumpkin puree makes the dough wetter and stickier than a plain sourdough. That’s normal. Wet your hands for the stretch and folds instead of adding more flour.
Leaving the Dutch oven in the oven too long. I’ve found that when the Dutch oven sits in the hot oven a long time after preheating, the bottom of the pan gets too hot and burns the bottom of the bread. It’s hard to cut through, and it’s not that nice soft, light-brown color. Preheat it with the oven, about 10 to 15 minutes, then bake.
Not checking the internal temperature. Pumpkin keeps the inside moist, so the crust can look done before the center is. Check for 200 to 205°F with an instant-read thermometer.
A Pumpkin Sourdough Loaf for Halloween and Thanksgiving
If you’re a busy mom looking for something special to make for your family this fall, this pumpkin cinnamon swirl sourdough is a great one. Most of the time is hands-off: the dough ferments on the counter, then proofs in the fridge overnight, so you can work around school drop-offs and a busy holiday week.
Toast a slice for a cozy Halloween morning breakfast before trick-or-treating, or bake a loaf to set out for Thanksgiving breakfast while the turkey is roasting. It also makes a sweet hostess gift. Because it freezes well, you can bake it ahead and pull it out of the freezer when the holidays get busy (see the storage section below).
Selling Pumpkin Cinnamon Swirl Sourdough at Your Microbakery
If you run a microbakery or a market stand, a pumpkin cinnamon swirl sourdough loaf (or any sourdough cinnamon swirl bread) is a wonderful seasonal item to add to your fall menu. Here’s how to plan around fall and holiday demand.
Why a Pumpkin Swirl Loaf Sells
Fall is one of the busiest seasons for baked goods, and pumpkin and cinnamon are flavors people look forward to all year. A swirl loaf also looks beautiful when it’s sliced, which makes it easy to share on social media and to show off at your table. For me, this loaf sells out the quickest at my markets.
Use Preorders and Limited Drops
Limited drops create excitement. When customers know a seasonal loaf is only available for a short time, they order early. Opening preorders also helps you know exactly how many loaves to bake, so you’re not guessing how much dough to mix. Share your drop dates ahead of time so your regulars can plan.
Let Customers Buy Multiples to Freeze
Sourdough freezes beautifully, so let customers order more than one loaf. Some people will want to stock up for the holidays or for later in the year. Include simple freezing and reheating instructions with each order (you can use the storage section below) so they know how to keep it fresh.
Plan for Thanksgiving and Christmas
Demand for seasonal bread climbs in the weeks before Thanksgiving and Christmas. Plan a preorder window that ends a few days before each holiday so you have time to feed your starter, mix, ferment, cold proof, and bake. Because this loaf needs a long bulk ferment and an overnight cold proof, build your schedule backward from your pickup or market day.
Fit It into a Rotating Menu
A rotating menu keeps customers coming back to see what’s new. Bring this loaf back for fall and the holidays, and let your customers know when it’s returning. When a favorite only shows up for a little while, people are excited to order it.
Before you sell, check your state’s cottage food rules for labeling and allergen requirements. This loaf contains wheat.
Can I Make This Pumpkin Sourdough Gluten Free?
I haven’t tested this recipe gluten free, so I can’t recommend a swap. Sourdough bread relies on gluten for its structure and rise, so a gluten-free version would need a different recipe.
How to Store and Freeze Pumpkin Cinnamon Swirl Sourdough
To store: once the loaf is completely cool, keep it on the counter in an airtight glass container or a cotton bread bag for 2 to 3 days. Store a cut loaf cut side down so it doesn’t dry out. Beeswax wrap works well too.
To freeze: cool the loaf completely first. You can freeze it whole or sliced. Slicing first is handy, because you can pull out just the slices you need. Wrap the loaf or slices tightly in beeswax wrap, or stack the slices with parchment paper between them in a freezer-safe glass container. If you use a freezer bag, press out as much air as you can. A plastic-free option is beeswax wrap with a cotton bread bag over it. Freeze for up to about 3 months.
To thaw and reheat: toast frozen slices straight from the freezer. For a whole loaf, thaw it on the counter in its wrap for a few hours. Then take off any wrap and warm the loaf on the oven rack at 350°F for about 10 to 15 minutes to refresh the crust.
This is exactly why so many of my customers order multiples, so they can freeze them for Thanksgiving, Christmas, and throughout the year.
FAQs for Pumpkin Cinnamon Swirl Sourdough
How long should pumpkin sourdough bread cool before slicing?
At least 1 hour, until it’s completely cool. The inside keeps setting as it cools, so slicing early makes it gummy and not fully set.
When do I add the cinnamon swirl?
After the bulk ferment is fully done, during shaping. Stretch the dough into a rectangle, sprinkle on the brown sugar and cinnamon, do a three-fold, and roll it up.
How do I know when my sourdough is done bulk fermenting?
Don’t just go by the clock. Fully fermented dough jiggles like Jell-O, has bubbles on the surface, looks smooth, and doesn’t spring right back when you gently poke it. If it bounces back immediately, keep fermenting.
How long does the bulk ferment take?
5 to 10 hours, depending on the dough temperature. At 70°F it takes about 8 to 9 hours. If you’re unsure, lean toward a little more proofed rather than underproofed.
Why is there pumpkin pie spice in the dough?
Pumpkin puree on its own is bland. Adding pumpkin pie spice to the dough, not just the filling, puts warm flavor in every bite.
How do I know the loaf is done baking?
Check it with an instant-read thermometer. It’s done when the inside reaches 200 to 205°F.
Can I freeze pumpkin cinnamon swirl sourdough?
Yes. Freeze it whole or sliced, wrapped tightly in beeswax wrap or in a freezer-safe glass container, for up to about 3 months. Toast slices from frozen, or thaw a whole loaf on the counter and warm it at 350°F.
How do I store it?
Keep the cooled loaf on the counter in an airtight glass container or a cotton bread bag for 2 to 3 days.
Can I make this recipe gluten free?
I haven’t tested this recipe gluten free, so I can’t recommend a swap.
