There is something magical about pulling a warm loaf of pumpkin sourdough bread out of the oven on a crisp autumn morning. The kitchen fills with the scent of toasted cinnamon and roasted pumpkin, and when you slice into the loaf, a soft spiral of cinnamon sugar unfurls through tender, golden crumb. This bread takes everything wonderful about a classic sourdough loaf, its chewy crust, its slightly tangy flavor, and folds in the cozy sweetness of pumpkin puree and warm baking spices.
This is the kind of bread you want to make when the weather turns cooler and you crave something that feels a little more special than an everyday sandwich loaf. It works beautifully for a slow weekend baking project, since sourdough naturally asks you to plan ahead with feeding your starter and allowing long, unhurried rises. Toast a slice and slather it with butter for breakfast, serve it alongside a bowl of soup for dinner, or wrap a loaf up as a homemade gift for a neighbor during the holidays.
SaveI first started making this loaf after craving my favorite pumpkin quick bread but wanting the deeper flavor and chewier texture that only a long fermented sourdough can give. The first time I unwrapped a cooled loaf and saw that perfect cinnamon swirl staring back at me, I knew this recipe was a keeper. It takes a bit of patience, but every step is simple, and the payoff is a loaf that tastes like fall in the best possible way.
Pumpkin Sourdough Bread with Cinnamon Swirl
Ingredients
Dough
Cinnamon Swirl Filling
Egg Wash
Instructions
- Feed your sourdough starter
The night before or the morning you plan to mix your dough, feed your sourdough starter with equal parts flour and water so it is active and bubbly, roughly doubled in size and floating when dropped in water. You will need 1 cup of this fed, lively starter for the dough, so plan your feeding schedule so the starter peaks about 4 to 6 hours before you begin mixing.
- Mix the pumpkin sourdough dough
In a large mixing bowl, whisk together the sourdough starter, pumpkin puree, milk, melted butter, and brown sugar until smooth and well combined. Add the bread flour, salt, cinnamon, nutmeg, cloves, and ginger, then stir with a wooden spoon or dough whisk until a shaggy, slightly sticky dough forms. The dough should feel tacky but not overly wet, since pumpkin puree naturally adds a lot of moisture.
- Knead and rest the dough
Turn the dough out onto a lightly floured surface and knead for about 8 to 10 minutes, until it becomes smooth and elastic, passing the windowpane test where a small piece can be stretched thin without tearing. If kneading by stand mixer, use the dough hook on low to medium speed for about 6 to 8 minutes. Shape the dough into a ball and place it in a lightly oiled bowl, cover with plastic wrap or a damp towel, and let it rest at room temperature for 30 minutes before bulk fermentation begins.
- Bulk ferment with stretch and folds
Over the next 4 to 6 hours, perform a set of stretch and folds every 30 minutes for the first 2 hours, then leave the dough undisturbed to continue rising. To stretch and fold, wet your hand, grab one side of the dough, stretch it upward, and fold it over the center, rotating the bowl and repeating on all four sides. The dough is ready for shaping when it has increased by about 50 to 75 percent in volume, feels airy and slightly jiggly, and holds a domed shape.
- Prepare the cinnamon swirl filling
While the dough ferments, stir together the granulated sugar, cinnamon, and a pinch of salt in a small bowl. Keep the softened butter separate so it stays easy to spread later. Set both aside at room temperature until you are ready to shape the loaf, so the butter remains soft and pliable for spreading.
- Shape and fill the loaf
Turn the fermented dough out onto a lightly floured surface and gently press it into a rectangle roughly 9 by 14 inches, taking care not to deflate all of the air bubbles. Spread the softened butter evenly over the surface, leaving a half inch border, then sprinkle the cinnamon sugar mixture evenly on top. Starting from one short end, roll the dough tightly into a log, pinching the seam closed and tucking the ends underneath to create a smooth, even loaf shape.
- Second rise in the loaf pan
Place the shaped loaf seam side down into a greased 9 by 5 inch loaf pan. Cover loosely with a damp towel or plastic wrap and let it rise at room temperature for 2 to 4 hours, or in the refrigerator overnight for 8 to 12 hours for deeper flavor, until the dough has risen about an inch above the rim of the pan and springs back slowly when gently poked.
- Preheat the oven and prepare the egg wash
About 30 minutes before baking, preheat your oven to 350 degrees Fahrenheit. Whisk the egg with the tablespoon of water to make an egg wash, then brush it gently and evenly over the top of the risen loaf, taking care not to deflate the dough. This egg wash will give the finished bread a beautiful glossy, golden crust.
- Bake the pumpkin sourdough loaf
Bake the loaf in the preheated oven for 40 to 45 minutes, tenting loosely with foil after 25 minutes if the top is browning too quickly. The loaf is done when it is deep golden brown, sounds hollow when tapped on the bottom, and reads about 195 to 200 degrees Fahrenheit on an instant read thermometer inserted into the center.
- Cool completely before slicing
Remove the loaf from the oven and let it rest in the pan for 10 minutes, then turn it out onto a wire rack to cool completely, at least 1 hour, before slicing. Cooling fully allows the interior crumb to finish setting, which prevents the cinnamon swirl from gumming up and gives you clean, even slices.
- Slice and serve
Once fully cooled, slice the loaf with a sharp serrated knife to reveal the swirled pattern running through the crumb. Serve slices as is, lightly toasted, or spread with butter, cream cheese, or a drizzle of honey for an extra cozy touch.
Substitutions and variations
- If you do not have bread flour, you can use all purpose flour instead, though the crumb will be slightly softer and less chewy.
- Whole milk can be swapped for oat milk or any unsweetened plant based milk to make this loaf dairy friendly when paired with a plant based butter.
- Brown sugar can be replaced with maple sugar or coconut sugar for a slightly different depth of sweetness.
- If your sourdough starter is on the sluggish side, you can add 1/4 teaspoon of instant yeast to the dough to help ensure a reliable rise, while still keeping much of the sourdough flavor.
- Pumpkin pie spice can be used in place of the individual cinnamon, nutmeg, cloves, and ginger measurements if you prefer a shortcut, using about 1 3/4 teaspoons total.
Chloe's tips
- Use a kitchen scale to measure your flour by weight when possible, since scooping flour with a cup can easily add too much and lead to a dense loaf.
- If your kitchen is cool, bulk fermentation may take longer than 6 hours, so watch the dough rather than the clock and look for visible signs of rise and airiness.
- Chilling the shaped dough overnight before baking not only fits easily into a busy schedule but also deepens the tangy sourdough flavor.
- Roll the dough tightly during shaping to avoid large gaps that can cause the cinnamon swirl to separate from the bread during baking.
How to store it
- Store the cooled loaf wrapped tightly in plastic wrap or in an airtight container at room temperature for up to 3 days.
- For longer storage, refrigerate sliced bread in an airtight container for up to a week, then toast slices to refresh their texture before serving.
- Freeze whole or sliced bread wrapped tightly in plastic and foil for up to 3 months, then thaw at room temperature or toast slices directly from frozen.
Serving suggestions
This pumpkin sourdough bread with cinnamon swirl is wonderfully versatile and can be enjoyed in many different ways throughout the day.

Frequently asked questions
Can I make this bread without a sourdough starter?
This recipe is built around the flavor and rise of an active sourdough starter, so it works best when you have one on hand. If you do not have a starter, you would need to substitute a yeasted pumpkin cinnamon bread recipe instead, since the fermentation times and hydration in this recipe are calibrated for sourdough.
Why is my dough too sticky to shape?
Pumpkin puree varies in moisture content between brands, so if your dough feels overly sticky, lightly flour your hands and work surface during shaping rather than adding extra flour to the dough itself, which can make the finished loaf dense.
Can I skip the overnight rise in the refrigerator?
Yes, you can let the shaped loaf rise entirely at room temperature for 2 to 4 hours instead of refrigerating it overnight. The overnight option simply allows for deeper sourdough flavor and a more flexible baking schedule.
Why did my cinnamon swirl separate from the bread while baking?
A gap in the swirl usually happens when the dough is rolled too loosely or when too much butter is used in the filling. Rolling the dough tightly and spreading a thin, even layer of butter before adding the cinnamon sugar helps the swirl stay connected to the crumb.
Can I add mix ins like chocolate chips or pecans?
Absolutely, you can sprinkle a half cup of chopped toasted pecans or chocolate chips over the cinnamon sugar layer before rolling the dough for extra texture and flavor.
