Instructions

Step 1: Make the Sourdough Buttermilk Brioche Dough

Method 1 (Autolyse Method – Recommended):

1. In the bowl of a stand mixer, combine sourdough starter, buttermilk, eggs, sugar, and flour. Mix on low speed until just combined into a shaggy dough.
2. Cover and let rest for 30 minutes (this is called autolyse and helps develop gluten).
3. After 30 minutes, sprinkle the salt and vanilla over the dough. Mix on medium speed for 3-4 minutes.
4. Add the softened butter one chunk at a time, mixing well between each addition. Continue mixing for 8-10 minutes until the dough is smooth, elastic, and pulls away from the sides of the bowl.

Method 2 (All-at-Once Method):

1. Simply combine all ingredients (sourdough starter, buttermilk, eggs, sugar, vanilla, flour, salt, and butter) in the bowl of a stand mixer.
2. Mix on medium speed for 10-12 minutes until smooth and elastic.

Both methods work! The autolyse method gives you slightly better gluten development, but the all-at-once method is faster and easier.

3. Bulk fermentation: Place dough in a lightly greased bowl, cover, and let rise at room temperature (68-72°F) for 8-12 hours, or until doubled in size.

Step 2: Make the Apple Pie Filling

1. In a large saucepan, combine diced apples, brown sugar, lemon juice, vanilla, cinnamon, nutmeg, ginger, salt, and butter.
2. Cook over medium heat, stirring occasionally, until apples are softened (about 8-10 minutes).
3. In a small bowl, mix the cornstarch with 3 tablespoons of water or apple cider until smooth (this is your slurry).
4. Pour the cornstarch slurry into the apple mixture and stir constantly until thickened (1-2 minutes).
5. Let the filling cool completely before using. This is crucial, hot filling will melt the butter in your brioche dough!

Pro tip: You can make this filling a day ahead and store it in the refrigerator.

Step 3: Shape the Brioche Swirl

1. Once your brioche dough has completed its bulk fermentation, turn it out onto a floured surface.
2. Roll the dough into a long rectangle, approximately 28-30 inches long and 4 inches wide. The dough should be about ¼-inch thick.
3. Spoon or pipe the cooled apple pie filling down the center of the dough strip lengthwise, leaving about 1 inch of dough on each side.
4. Fold like a taco: Bring one long edge of dough up and over the filling, then fold the other side over to create a filled tube with the seam on top or to the side. The filling should be visible along the top opening.
5. Grease your 10-inch springform pan lightly and line with parchement.
6. Coil the dough: Starting from one end, gently coil the filled dough rope into a spiral shape, placing it in the center of your prepared springform pan. Continue coiling outward until you’ve used all the dough, with the open seam facing UP so you can see the apple filling. Adjust as needed once all the dough is in the pan.

Step 4: Final Proof

1. Cover the pan loosely with plastic wrap or a clean bag.
2. Let proof at room temperature until puffy and jiggly (this took about 4 hours for me, but yours may be faster or slower).

How to tell when it’s properly proofed:

• The dough should look puffy and have expanded noticeably
• When you gently press a finger into the dough, it should slowly spring back but leave a slight indent
• Don’t go by time alone – ambient temperature affects proofing speed significantly

Under-proofed signs: Dough is tight, dense, springs back immediately when poked
Over-proofed signs: Dough is very slack, doesn’t spring back at all when poked, may have a sour smell

Step 5: Bake

1. Preheat your oven to 350°F (175°C).
2. Gently brush the top of the proofed brioche with egg wash (avoid deflating the dough).
3. Bake for 60-70 minutes, until deep golden brown on top. If it’s browning too quickly, tent loosely with foil after 25 minutes.
4. The internal temperature should reach 190-200°F when done.
5. Let cool in the pan for 10-15 minutes, then carefully remove the springform ring.

Step 6: Make the Caramel Vanilla Glaze

1. In a microwave-safe bowl, add the water and then slowly pour the sugar into the middle of the bowl. Do not stir.
2. Microwave for 1 minute, then begin 30 second intervals (watching closely!) until the mixture turns amber colored. Be careful – it’s extremely hot!
3. Carefully stir in the warmed heavy cream (it will bubble up!), butter, vanilla, and salt.
4. Let cool for 5-10 minutes until just warm.
5. Whisk in 40-60g powdered sugar until you reach a pourable glaze consistency. Add more warm cream if needed to thin it out.

Step 7: Glaze and Serve

1. While the brioche is still slightly warm, drizzle the caramel vanilla glaze generously over the top.
2. Let the glaze set for a few minutes, then slice and serve!

How to Serve

Cut this beauty into wedges like you would a cake or pie, straight down from the center outward. The layers will pull apart beautifully, revealing all those gorgeous swirls and pockets of apple filling.

Serve it warm or at room temperature. It’s incredible on its own, but here are some next-level serving suggestions:

• With a scoop of vanilla ice cream
• Alongside your morning coffee (it’s basically a fancy breakfast pastry)
• Warmed up with extra caramel drizzle
• With a dollop of whipped cream

Yeast Version

No sourdough starter? No problem. This brioche swirl works beautifully with active dry yeast and comes together the same day in about 3 hours start to finish.

Ingredients

690g (5 3/4 cups) all-purpose flour
340g (1 cup + 1/3 cup + 1 tbsp) buttermilk, warmed to 105 to 110F
7g (2 1/4 tsp or 1 standard packet) active dry yeast
2 whole eggs, room temperature
60g (1/4 cup + 1 tbsp) granulated sugar
7g (1 3/4 tsp) vanilla extract
6g (1 tsp) salt
60g (4 tablespoons) unsalted butter, softened

Buttermilk alternative: Use whole milk in the same amount. To make a quick buttermilk substitute, add 1 tablespoon of white vinegar or lemon juice to your measured milk and let it sit for 5 minutes before using.

Instructions

Warm your buttermilk to 105 to 110F. Sprinkle the yeast over the warm buttermilk and let it sit for 5 to 10 minutes until foamy. If it does not foam, your yeast is not active and needs to be replaced.

Add the eggs, sugar, and vanilla to the yeast mixture and whisk to combine.

Add the flour and salt and mix on low speed until a shaggy dough forms, then increase to medium and mix for 3 to 4 minutes.

Add the softened butter one chunk at a time, mixing well between each addition. Continue mixing for 8 to 10 minutes until the dough is smooth, elastic, and pulls away from the sides of the bowl.

Place the dough in a lightly greased bowl, cover, and let rise at room temperature until doubled in size, about 1 to 1.5 hours.

Once risen, shape, fill, and coil exactly as directed in the main recipe above.

After shaping, cover and let proof for 45 minutes to 1 hour until puffy and jiggly before baking as directed.

Tips for Success

• Temperature matters: Make sure your butter and eggs are at room temperature for the brioche dough
• Cool that filling: Don’t skip letting the apple filling cool completely – hot filling = melted butter = sad dough
• Length flexibility: If you can’t roll to 28-30 inches, that’s okay! A shorter, thicker spiral is just as delicious
• Watch the proof: Trust visual/tactile cues for proofing, not just the clock
• Tent if needed: If the top is browning too fast, loosely cover with foil
• Glaze while warm: The glaze sets better and looks glossier when applied to slightly warm brioche

FAQ

My dough is too sticky to work with. Help!
Brioche dough is naturally on the stickier side. If it’s unmanageable, pop it in the fridge for 15-20 minutes to firm up, then roll it on a well floured surface.

Can I use store bought apple pie filling?
You can, but homemade is SO much better and you can control the consistency. If using store bought, drain excess liquid first.

What apples work best?
Keepsake, Granny Smith, Honeycrisp, or a mix! You want apples that hold their shape when cooked and aren’t too watery.

How do I know when it’s done baking?
Look for deep golden brown color on top and an internal temperature of 190-200°F. The bottom should also be golden (you can carefully lift it to check).

Can I make this in a different size pan?
An 8-inch or 9-inch pan will work, you’ll just have a taller spiral. And may require longer baking. A larger pan will give you a flatter, wider spiral.

Variations to Try

• Pear Version: Swap apples for pears and add cardamom
• Berry Swirl: Use mixed berry filling instead of apple
• Pumpkin Spice: Add pumpkin puree and pumpkin pie spice to the filling
• Chocolate Drizzle: Add melted chocolate on top with the caramel
• Nutty: Sprinkle chopped pecans or walnuts over the filling before rolling

Why This Recipe Works

The magic of this recipe is in the combination of:

• Buttermilk for extra tenderness in the brioche
• Cooked apple filling that’s already soft and won’t release excess moisture during baking
• Caramel glaze that adds that bakery-quality finish and is so easy to make.

This is the kind of bake that looks incredibly impressive but is actually quite forgiving. The brioche dough is sturdy enough to handle the rolling and coiling, and the cooked apple filling means no surprises with liquid seeping out during baking.

The result is a stunning centerpiece that’s perfect for fall gatherings, holiday brunches, or just because you deserve something spectacular. Your kitchen will smell absolutely incredible, and the reactions when you bring this to the table? Priceless.
