Fluffy Sourdough Cinnamon Rolls (Overnight Option)
Sourdough cinnamon rolls bring together everything you want in a morning pastry: a tender, yeasted swirl with that subtle tang only a sourdough starter can give. This version uses discard straight from the fridge, so you can mix the dough when it suits you and bake fresh rolls the next day.
They rise up tall and soft, with a cinnamon-brown sugar ribbon that melts into every layer, all under a tangy cream cheese glaze. No fancy schedule, no wasted starter, just a little planning and a whole lot of reward.
What Makes These Rolls So Good
The sourdough tang cuts through the sweetness so the rolls never feel cloying. That bit of acid also relaxes the gluten, which means a dough that rolls out smoothly and bakes up incredibly soft.
I reach for unfed discard because I almost always have some in the fridge. A long, slow rise builds the same flavor and lift as a freshly fed starter, so I can start the dough after dinner and have warm rolls by brunch with almost no morning work.
Ingredients
- 1/2 cup (120g) sourdough starter discard: cold from the fridge is fine, no feeding needed
- 1/2 cup (120ml) whole milk: warmed to about 100°F (38°C), 2% also works
- 1/4 cup (56g) unsalted butter: melted and cooled slightly
- 1/4 cup (50g) granulated sugar
- 1 large egg: at room temperature
- 3 1/2 cups (420g) all-purpose flour: plus more for dusting
- 1/2 teaspoon fine sea salt
- 1/2 cup (100g) packed light brown sugar: for the filling
- 2 tablespoons ground cinnamon
- 3 tablespoons unsalted butter: very soft, for spreading
- 4 oz (113g) full-fat cream cheese: softened
- 1 cup (120g) powdered sugar
- 2 tablespoons milk: for the frosting, plus a splash more if needed
- 1/2 teaspoon vanilla extract
Variations / Substitutions
- Whole wheat flour: swap in up to 1 cup (120g) of the all-purpose flour for a nuttier, heartier crumb. The dough will be slightly denser.
- Active starter: if your starter is bubbly and fed, use it in place of the discard. Rise times will be about half as long, so keep an eye on the dough rather than the clock.
- Dairy-free: use oat milk, vegan butter sticks, and a dairy-free cream cheese alternative. The frosting will be a little softer but still delicious.
- Extra gooey filling: sprinkle 2 tablespoons of heavy cream or melted butter over the brown sugar layer before rolling for a stickier, more caramelized center.

How to Make Fluffy Sourdough Cinnamon Rolls
Step 1: Mix and Knead the Dough
Warm the 1/2 cup milk until it feels just lukewarm, about 100°F (38°C). Pour it into a large bowl and stir in the 1/4 cup melted butter, 1/4 cup granulated sugar, the 1/2 cup sourdough discard, and the egg until everything looks blended and smooth.
Add 3 cups of the flour and the 1/2 teaspoon salt, mixing with a wooden spoon until a shaggy dough forms. Turn it out onto a lightly floured counter and knead for 8 to 10 minutes, working in up to 1/2 cup more flour as you go. The dough will go from sticky and rough to smooth and elastic, and it should spring back when you poke it.
Step 2: Roll Out and Fill the Dough
Once the dough has doubled in size, punch it down gently and turn it onto a lightly floured surface. Roll it into a 16×12-inch rectangle, lifting and stretching the corners to keep the shape even. Spread the 3 tablespoons of softened butter all the way to the edges, leaving a bare 1/2-inch border on one long side.
Mix the 1/2 cup brown sugar with the 2 tablespoons cinnamon and scatter it evenly over the butter. Press the filling lightly with your palms so it sticks. Starting from the opposite long side, roll the dough up tightly like a jelly roll, pulling back a little as you go to keep tension. Pinch the seam to seal.
Step 3: Shape and Cut the Rolls
Slide the log seam side down and use a sharp serrated knife to cut it into 9 equal pieces, each about 1 3/4 inches thick. Tuck any loose ends under and arrange the rolls cut side up in a 9-inch round cake pan lined with parchment. They’ll look small now, but they’ll fill the pan completely after the next rise.
Press down on the tops very gently so they sit at roughly the same height. If a spiral pops loose, just tuck it back in. At this point you can either let them rise on the counter or pop them in the fridge for the overnight option.
Step 4: Let the Rolls Rise
Cover the pan loosely with plastic wrap or a damp towel and let the rolls rise at room temperature until they’ve doubled in size and are touching each other, about 1 1/2 to 2 hours. A warm, draft-free spot works best.
If you’re going the overnight route, place the covered pan in the fridge as soon as it’s shaped. The next morning, pull it out and let the rolls finish rising on the counter for 45 to 60 minutes. They should feel puffy and light, not dense, before they go into the oven.
Step 5: Bake Until Golden
Heat your oven to 375°F (190°C) and set a rack in the middle. Once the rolls are fully risen, slide the pan in and bake for 22 to 25 minutes. The tops will turn deep golden brown, and an instant-read thermometer poked into the center of a roll should register around 190°F (88°C).
If the tops are browning too quickly after 15 minutes, tent the pan loosely with foil. Pull them out and let the pan cool on a rack for 10 minutes. The carryover heat finishes setting the centers while you make the frosting.
Step 6: Drizzle with Cream Cheese Frosting
While the rolls cool a bit, beat the 4 ounces softened cream cheese with 1 cup powdered sugar, 2 tablespoons milk, and 1/2 teaspoon vanilla until smooth. The frosting should be thick but pourable, so add another splash of milk if it seems stiff.
Spoon the frosting over the still-warm rolls, letting it melt into all the nooks and crannies. Pull them apart and serve while they’re warm and soft, with extra napkins close by.
Tips for the Softest Rolls
- Use a kitchen scale for the flour if you can. 3 1/2 cups all-purpose flour should weigh about 420g, and measuring by volume can pack in too much, leading to a dry dough.
- Don’t rush the second rise. The rolls need to feel puffy and light, not dense, before they go in the oven. A cool kitchen might add an extra 30 minutes, and that’s fine.
- For clean, even slices, try unflavored dental floss. Slide it under the log, cross the ends, and pull. It cuts without squishing the dough and keeps the swirls neat.
- If you like extra gooey bottoms, pour 3 tablespoons of warm heavy cream over the risen rolls just before baking. It seeps down and creates a soft, almost caramelized base.
Bake times by pan type:
| Pan Type | Size | Bake Time |
|---|---|---|
| Round cake pan | 9-inch | 25-28 mins |
| Rectangular pan | 9×13-inch | 22-25 mins |
Keeping Leftovers Fresh
Store leftover rolls in an airtight container at room temperature for up to 2 days, or in the fridge for up to 5 days. Reheat individual rolls in the microwave for 15 to 20 seconds, or warm the whole pan in a 300°F (150°C) oven for about 10 minutes. The cream cheese frosting holds up well, but a fresh drizzle never hurts.
Frequently Asked Questions
Can I use an active, bubbly sourdough starter instead of discard?
Yes. The rise times will be shorter. Start checking the dough after about 1 hour for the first rise and 45 minutes for the second, and bake when the rolls are doubled and feel light.
Why did my rolls come out dense?
Your starter might not have had enough lift for the heavy dough, or the second rise wasn’t long enough. Make sure the rolls are genuinely doubled and feel soft to the touch before they go in the oven.
Can I make these completely ahead and freeze them?
You can freeze the unbaked rolls. After cutting and arranging them in the pan, cover tightly and freeze for up to 1 month. Thaw overnight in the fridge, let them rise on the counter, then bake as directed.
What if I don’t have a stand mixer?
This dough comes together easily by hand. Mix with a wooden spoon until it’s too stiff, then turn it out and knead. It’s a great arm workout and gives you a better feel for when the dough is smooth and ready.
