Sourdough Brown Butter Peach Cobbler Cinnamon Rolls

Ingredients

Levain (build the night before)

A ripe levain replaces the commercial yeast. Build it 6 to 10 hours ahead so it is bubbly and active.

• 45g (6 Tbsp) bread flour
• 45g (3 Tbsp) water, room temperature
• 10g (2 tsp) active sourdough starter

Tangzhong

The cooked-flour paste that keeps these rolls soft for days.

• 25g (3 Tbsp) bread flour
• 125g (½ cup + 1 tsp) whole milk

The Dough

Enriched with milk, egg, and butter for a pillowy crumb.

• 400g (3⅓ cups) bread flour
• 50g (¼ cup) granulated sugar
• 9g (1½ tsp) fine salt
• 100g (½ cup) ripe levain (all of it)
• 100g (6½ Tbsp) warm whole milk
• 50g (1 large egg) large egg
• 18g (1 large yolk) large egg yolk
• 60g (4 Tbsp) softened unsalted butter
• 5g (1 tsp) vanilla extract

Roasted Peach Filling

Real fruit, roasted down to a thick, jammy filling with no free liquid.

• 500g (3⅓ cups) peaches, peeled and diced
• 50g (¼ cup) light brown sugar
• 8g (1 Tbsp) cornstarch
• 2g (1 tsp) ground cinnamon
• 0.5g (¼ tsp) ground nutmeg
• 15g (1 Tbsp) lemon juice
• 1g (⅛ tsp) fine salt

Cinnamon Smear

A spreadable paste that clings to the dough instead of running out the ends.

• 57g (4 Tbsp) softened unsalted butter
• 100g (½ cup) dark brown sugar
• 6g (1 Tbsp) ground cinnamon
• 1g (⅛ tsp) fine salt

Brown Butter Streusel

The topping that fills the whole house with smell while it bakes.

• 85g (6 Tbsp) unsalted butter
• 95g (¾ cup) all-purpose flour
• 50g (¼ cup) light brown sugar
• 25g (2 Tbsp) granulated sugar
• 2g (1 tsp) ground cinnamon
• 0.5g (¼ tsp) ground nutmeg
• 1g (⅛ tsp) fine salt

Buttermilk Glaze

A tangy finish that plays against all that warm spice.

• 120g (1 cup) powdered sugar
• 30g (2 Tbsp) buttermilk
• 2g (½ tsp) vanilla extract
• 0.5g (⅛ tsp) fine salt

Total flour: 475g

Hydration: 58%

Pro tip: The overnight cold retard is doing two jobs at once. It develops that gentle sourdough tang, and it firms the butter so the dough rolls out clean instead of tearing.

Equipment

• Stand mixer with dough hook
• Small saucepan (for the tangzhong)
• Rimmed baking sheet (for roasting the peaches)
• 9x13-inch baking pan
• Rolling pin
• Bench scraper
• Instant-read thermometer
• Unflavored dental floss or a sharp knife
• Offset spatula
• Whisk

Method

Build the Levain

This is where sourdough replaces the yeast. A ripe levain is what lifts these rolls, so give it time to wake up.

1. Mix the levain. Stir together the bread flour, water, and active starter in a small jar until no dry flour remains. Cover loosely and leave at room temperature.
2. Wait for ripe. It is ready when it has roughly doubled, looks domed and bubbly, and passes the float test. Usually 6 to 10 hours depending on your kitchen.

Wait: PT8H

Tip: Cool kitchen? Give it the full 10 hours. Warm kitchen? Start checking at 5.

Make the Tangzhong

The tangzhong is a cooked-flour paste that locks in moisture and keeps the crumb soft.

1. Cook the paste. Whisk the bread flour and milk in a small saucepan. Cook over medium-low, stirring, for 2 to 3 minutes, until a whisk track holds on the bottom.
2. Cool it down. Scrape into a bowl, press wrap on the surface, and cool to just warm before it goes into the dough.

Tip: Cold tangzhong is fine. Just don't add it hot or it'll cook your egg.

Mix the Dough

Build an enriched dough, adding the butter last so the gluten sets up first.

1. Dry mix. In the stand mixer bowl, whisk the bread flour, sugar, and salt until even.
2. Wet mix. Add the ripe levain, warm milk, egg, yolk, vanilla, and the cooled tangzhong. Mix low with the dough hook to a shaggy mass, about 2 minutes.
3. Butter and knead. Add the softened butter a tablespoon at a time, then knead on medium-low 8 to 10 minutes to a smooth, tacky, windowpane test dough.

Tip: Sourdough enriched dough kneads a little longer than yeasted. Be patient and let it come together before you judge it.

Bulk Ferment

This is the long, slow rise. Trust the dough cues from bulk fermentation, not the clock.

1. Rise. Round the dough, cover, and rise in a warm spot until visibly aerated and about 50 to 75 percent larger. Usually 4 to 6 hours, longer in a cool kitchen.

Wait: PT5H

Tip: Don't wait for a full double like a lean sourdough. Enriched dough moves slower and you'll finish the rise in the pan.

Cold Retard Overnight

The cold retard develops flavor and firms the butter so the dough rolls clean.

1. Chill. Cover the bowl tightly and refrigerate 8 to 16 hours, overnight is perfect. The dough will firm up and deepen in flavor.

Wait: PT12H

Roast the Peaches

Roast the fruit down to a thick jam. The target weight is the whole game here.

1. Toss and roast. Toss the peaches with the brown sugar, cornstarch, cinnamon, nutmeg, lemon juice, and salt. Roast on a rimmed sheet at 425F (220C) for 20 to 25 minutes, until jammy.
2. Hit the target. After roasting and cooling, target 325 to 375g with no free liquid on the pan. If it's watery, roast 3 to 5 minutes more. Cool completely before you fill.

Tip: Cool the filling completely. Warm filling melts the smear and slides right out of the rolls.

Cinnamon Smear and Brown Butter Streusel

Two components you can make while the dough retards, so both are ready and cool at assembly.

1. Cinnamon smear. Stir the softened butter, dark brown sugar, cinnamon, and salt into a spreadable paste.
2. Brown the butter. Melt the butter in a light pan and swirl until the milk solids turn deep golden and smell like toasted nuts, about 4 to 6 minutes. Off heat.
3. Make the streusel. Stir the AP flour, both sugars, cinnamon, nutmeg, and salt into the brown butter to clumps. Chill in the freezer until you need it.

Tip: If you drained juice off the roasted peaches, reduce it into the brown butter for another layer of peach flavor.

Roll, Fill, and Cut

Work with cold dough and cool filling so everything stays put.

1. Roll out. Turn the cold dough onto a floured counter and roll to an 18x14-inch rectangle, long side facing you.
2. Fill. Spread the smear across, leaving the bottom inch bare. Spoon the cooled peaches thin and even over the smear.
3. Roll and cut. Roll into a snug log from the top long edge. Pinch the seam. Trim a half inch from each end. Cut 12 rolls with unflavored dental floss.

Tip: Leaving the bottom inch bare gives you a clean seam to seal, so the log doesn't unroll in the pan.

Pan and Final Proof

The final rise is longer than the yeasted version. Watch the dough with a poke test, not the clock.

1. Pan the rolls. Butter a 9x13 pan and place the rolls cut side up with a little room between them.
2. Proof. Cover and proof at room temperature until puffy and just touching, about 2 to 4 hours. Preheat the oven to 350F (175C) near the end.

Wait: PT3H

Tip: Poke a roll gently. It should spring back slowly and leave a slight dent. That's ready.

Streusel and Bake

Scatter the cold streusel over the tops and bake until deep golden and set.

Oven: 175°C / 350°F. Internal temperature when done: 88-91°C / 190-195°F.

9x13 Pan, Center Rack (recommended)

The standard bake for these rolls.

Equipment: 9x13-inch baking pan

1. Streusel. Scatter the cold streusel heavily across the tops.
2. Bake. Bake at 350F (175C) for 28 to 32 minutes on the center rack, until deep golden and set.
3. Check doneness. Insert an instant-read thermometer into the dough portion of a center roll, not a peach pocket. Pull at 190 to 195F (88 to 91C). Tent with foil if the tops brown too fast.

Note: Always check the dough, not a peach pocket. The peaches read hotter and will fool you.

Storage

• Room temperature: Best day-of. Keep covered at room temperature for 1 day.
• Refrigerated: Refrigerate leftovers after 24 hours, since the buttermilk glaze is fresh dairy. Up to 4 days.
• Frozen: Freeze unglazed rolls up to 2 months. Glaze fresh after reheating.
• Refresh: Warm in a 350F (175C) oven for about 10 minutes, or microwave a single roll 20 to 30 seconds.

Frequently Asked Questions

I want the faster version. Is there a yeasted one?

Yes. The yeasted version bakes same-day in a few hours. Use the linked recipe if you're short on time. This sourdough version trades speed for flavor and a longer shelf life.

How do I know my levain is ready?

It should be roughly doubled, domed, and bubbly, and a small spoonful should float in water. If it's flat or sluggish, give it more time or feed your starter and try again tomorrow.

Can I skip the cold retard?

You can proof and bake the same day after bulk, but the cold retard is doing real work here. It builds flavor and firms the butter so the dough rolls clean. If you skip it, chill the shaped log 30 minutes before cutting.

No buttermilk for the glaze?

Stir a half teaspoon of lemon juice into 2 tablespoons of milk and let it sit 5 minutes. It won't be identical, but it gives you that tangy finish.

No fresh peaches where I am. What else works?

Frozen peaches, thawed and drained well, work year round. Canned peaches drained hard and patted dry are fine too. Apples and pears also make a great cobbler roll. Whatever you use, drain the water so the filling doesn't go soupy.

My rolls leaked and the bottoms went soggy. What happened?

Almost always too much liquid in the filling. Roast the peaches down to 325 to 375g with no free liquid on the pan, and make sure the filling is fully cool before you spread it.
