Prep Time

Prep Time: 45 minutes
Bulk Fermentation: 6–8 hours
Cold Proof: 8–12 hours (optional but recommended)
Bake Time: 40–45 minutes
Total Time: About 16–20 hours

Yield: 1 large loaf (10–12 slices)

Ingredients

For the Dough

500g bread flour
100g active sourdough starter (100% hydration)
330g lukewarm water
10g fine sea salt
30g unsalted butter, softened
30g granulated sugar
1 teaspoon vanilla extract (optional)

Cinnamon Swirl Filling

70g unsalted butter, softened
120g brown sugar
2 tablespoons ground cinnamon
1 tablespoon all-purpose flour (helps keep the swirl intact)
Pinch of salt

Optional Egg Wash

1 egg
1 tablespoon milk

Equipment

Dutch oven or bread cloche
Banneton basket or bowl lined with a towel
Bench scraper
Mixing bowl
Kitchen scale
Rolling pin
Sharp lame or bread knife
Cooling rack

Instructions

Step 1: Feed Your Starter

Feed your sourdough starter about 4–6 hours before mixing the dough. It should be bubbly, active, and at its peak when used.

A healthy starter is the key to achieving a light, fluffy loaf with excellent oven spring.

Step 2: Mix the Dough

In a large mixing bowl combine:

Active sourdough starter
Water
Sugar
Vanilla (if using)

Stir until the starter dissolves.

Add the bread flour and mix until no dry flour remains.

Cover and allow the dough to rest for 30 minutes. This autolyse period helps develop gluten naturally.

Step 3: Add Salt and Butter

Sprinkle the salt over the dough.

Add the softened butter a little at a time, kneading until completely incorporated.

The dough will become smooth, soft, and elastic after several minutes of kneading.

Step 4: Bulk Fermentation

Cover the bowl.

Allow the dough to ferment for 6–8 hours at 72–76°F (22–24°C).

During the first 2 hours perform four sets of stretch and folds every 30 minutes.

Each fold strengthens the gluten and creates a lighter crumb.

The dough should rise about 50–75% but does not need to double completely.

Prepare the Cinnamon Filling

Mix together:

Softened butter
Brown sugar
Cinnamon
Flour
Pinch of salt

Stir until a thick spreadable paste forms.

Set aside.

Shape the Dough

Turn the fermented dough onto a lightly floured surface.

Gently stretch or roll it into a rectangle approximately:

10 × 16 inches (25 × 40 cm)

Spread the cinnamon filling evenly over the dough, leaving a 1-inch border around all edges.

Starting from the short side, tightly roll the dough into a log.

Pinch the seam closed carefully.

Tuck the ends underneath.

Place seam-side up into a floured banneton.

Final Proof

Option 1:

Allow the dough to proof at room temperature for 1½–2 hours.

Option 2 (Recommended):

Cover and refrigerate overnight for 8–12 hours.

Cold proofing improves flavor, makes scoring easier, and creates a more defined swirl.

Preheat the Oven

Preheat your oven to 475°F (245°C) with a Dutch oven inside for at least 45 minutes.

A thoroughly heated Dutch oven creates excellent oven spring and crust.

Score the Dough

Carefully transfer the loaf onto parchment paper.

Dust lightly with flour if desired.

Using a lame or sharp knife, score one long slash across the top.

If using an egg wash for a softer crust, brush it lightly over the loaf before baking.

Bake

Place the loaf into the hot Dutch oven.

Cover with the lid.

Bake for:

20 minutes covered
Remove the lid
Reduce oven temperature to 450°F (232°C)
Bake another 20–25 minutes until deeply golden brown.

The internal temperature should reach approximately 205–210°F (96–99°C).

Cool

Transfer the loaf to a wire rack.

Allow it to cool for at least 2 hours before slicing.

This cooling period allows the crumb to finish setting and prevents a gummy texture.

Tips for Success

Use a very active sourdough starter.
Avoid adding too much filling, which can cause gaps in the loaf.
Roll the dough tightly to create an even swirl.
Refrigerating overnight develops a richer flavor.
Let the bread cool completely before slicing.
Bread flour provides the best structure for enriched sourdough.

Variations

Apple Cinnamon

Add ½ cup finely diced dried apples to the filling.

Raisin Cinnamon

Mix in ½ cup raisins or golden raisins.

Maple Pecan

Add chopped toasted pecans and drizzle maple syrup into the filling.

Orange Cinnamon

Mix orange zest into the cinnamon sugar for a fresh citrus flavor.

Chocolate Cinnamon

Sprinkle mini chocolate chips over the filling before rolling.

Serving Suggestions

This bread is delicious served:

Warm with salted butter
Toasted with cream cheese
With apple butter or pumpkin butter
As French toast
For bread pudding
Alongside coffee or chai tea
With vanilla ice cream for dessert

Storage

Store in an airtight container or bread bag for up to 4 days at room temperature.

For longer storage, freeze sliced bread for up to 3 months.

Toast slices directly from frozen whenever needed.

Frequently Asked Questions

Can I use all-purpose flour?

Yes, although bread flour produces a taller loaf with better structure and chew.

Can I make it without butter?

Yes. Substitute softened coconut oil or a neutral vegetable oil, though the flavor and texture will be slightly different.

Why did my cinnamon swirl separate?

Too much filling or rolling the dough too loosely can create gaps. Adding a little flour to the filling and rolling tightly helps the layers stay together.

Can I add nuts or dried fruit?

Absolutely. Chopped pecans, walnuts, raisins, dried cranberries, or dried apples all pair wonderfully with the cinnamon swirl.

Can I freeze this bread?

Yes. Slice the cooled loaf, wrap it well, and freeze for up to three months. Toast individual slices directly from the freezer for the best texture.
