Overnight Sourdough Discard Cinnamon Rolls
These overnight sourdough discard cinnamon rolls turn leftover starter into the softest, fluffiest cinnamon rolls you can make. They require almost no morning effort: mix the dough the night before, let the fridge do the work, then roll, fill, and bake the next day.

The discard brings a gentle tang that balances the buttery brown sugar swirl, and the cold rise makes the dough easy to handle. Perfect for lazy weekends or holiday mornings when you want a fresh baked treat without an early alarm.
Why These Sourdough Cinnamon Rolls Work
The biggest reason: they use discard you would otherwise throw away, and they taste so much better than plain yeast rolls. The sourdough adds a subtle complexity that cuts through the sweetness, so each bite feels balanced rather than cloying.
The overnight rise does all the heavy lifting for you. Cold dough rolls out cleanly and slices without squishing, so the spirals stay tight. And the tang from the discard keeps the rolls from going stale quickly — they stay soft for days.
Ingredients

- 3 1/2 cups (440g) all-purpose flour: plus more for dusting
- 1/2 cup (120g) sourdough discard: unfed, straight from the fridge is fine
- 1/4 cup (50g) granulated sugar: feeds the yeast and sweetens the dough lightly
- 1 tsp fine sea salt
- 2 1/4 tsp (1 packet) instant yeast: gives the rolls a reliable lift; if you only have active dry, see Variations
- 1/2 cup (120ml) whole milk, warm (110°F): 2% works, but whole milk makes a richer dough
- 1/4 cup (60g) unsalted butter, melted and cooled slightly
- 1 large egg, at room temperature
For the filling
- 1/2 cup (115g) unsalted butter, very soft: you want it spreadable, not melted
- 3/4 cup (150g) packed light brown sugar
- 2 tbsp ground cinnamon
For the frosting
- 4 oz cream cheese, softened
- 3 tbsp unsalted butter, softened
- 1 cup (120g) powdered sugar: sift if lumpy
- 1 tsp vanilla extract
- Pinch of salt
- 1 to 2 tbsp milk: as needed
Variations / Substitutions
- Active dry yeast: substitute 2 1/4 tsp active dry yeast; dissolve in the warm milk with a pinch of sugar and let it bloom for 5 minutes before mixing.
- Dairy-free: use a stick-style vegan butter, unsweetened almond or oat milk, and a vegan cream cheese for the frosting. The rolls will be a touch less rich but still very good.
- No commercial yeast: you can skip it, but the rise will take 3 to 4 hours at room temperature instead of overnight. For a naturally leavened method, see Sourdough Cinnamon Rolls.

How to Make Overnight Sourdough Discard Cinnamon Rolls
Step 1: Mix the Dough

In a large bowl, whisk together 3 cups of the flour (390g), the 1/4 cup sugar, 1 tsp salt, and the instant yeast. In a separate bowl or liquid measuring cup, combine the 1/2 cup warm milk, the 1/4 cup melted butter, the egg, and the 1/2 cup sourdough discard. Whisk until smooth, then pour the wet mixture into the dry ingredients.
Stir with a wooden spoon until a shaggy dough forms. Turn it onto a floured surface and knead for 5 to 6 minutes, adding the remaining 1/2 cup (50g) flour a tablespoon at a time as needed, until the dough is smooth, elastic, and only slightly tacky. It should feel soft and pillowy, springing back when you press it. A very slightly sticky dough yields the softest rolls, so resist adding too much extra flour.
Step 2: Chill the Dough Overnight

Shape the dough into a ball, place it in a lightly greased bowl, and turn it to coat. Cover tightly with plastic wrap and refrigerate for at least 8 hours, up to 24 hours. The cold rise allows the dough to double slowly and develop a gentle sour flavor.
In the morning, the dough should be puffy and feel cold but pliable. The chilled temperature makes it easy to roll out without the butter in the filling melting too soon, keeping the swirls neat and defined.
Step 3: Roll Out the Filling

On a lightly floured surface, roll the cold dough into a 12×18-inch rectangle, about 1/4 inch thick. Spread the 1/2 cup very soft butter evenly over the dough, leaving a 1/2-inch border along one long side. Combine the 3/4 cup brown sugar and 2 tbsp cinnamon in a small bowl, then sprinkle the mixture over the butter, pressing gently so it sticks.
Make sure the butter is spreadable, not melted, so you get an even layer. The cinnamon sugar should cover the butter right up to the border edges. A little overhang is fine, but the clean border helps seal the roll later.
Step 4: Shape and Slice the Rolls

Starting from the long side opposite the bare border, roll the dough tightly into a log. Pinch the seam to seal, then cut the log into 12 equal slices, each about 1 1/2 inches thick. A sharp serrated knife or unflavored dental floss works best. For floss, slide it under the log, cross the ends, and pull; it gives the cleanest edges.
Arrange the rolls cut-side up in a greased 9×13-inch baking dish or high-sided sheet pan, spacing them evenly. They will be snug but not crowded. As they proof, they will puff up and fill all the gaps.
Step 5: Proof and Bake

Cover the dish loosely with plastic wrap or a clean towel. Let the rolls rise in a warm spot until noticeably puffed and nearly doubled, about 45 to 60 minutes depending on room temperature. Near the end of the rise, preheat the oven to 350°F (180°C).
Bake on the middle rack for 22 to 25 minutes, until the tops are golden brown and the centers look set. If you check with an instant-read thermometer, the interior should be around 190°F. If the rolls brown too fast, tent loosely with foil for the last 5 minutes of baking.
Step 6: Frost While Warm

While the rolls bake, beat the 4 oz cream cheese and 3 tbsp softened butter together until smooth. Sift in the 1 cup powdered sugar, add the 1 tsp vanilla and a pinch of salt, and beat until fluffy. Thin with milk, 1 tbsp at a time, until the frosting is thick but easily spreadable.
Once the rolls come out of the oven, let them cool in the dish for just 5 minutes. Then slather the frosting over the warm rolls with an offset spatula. The heat will soften the frosting into a glossy, melty layer that seeps into every swirl. Serve them straight from the pan while they are still warm.
Tips for Perfect Overnight Cinnamon Rolls
- For a deeper tang, go for the full 24-hour cold ferment. The longer the dough sits, the more sourdough character you get.
- To make the morning even smoother, assemble the rolls in the baking dish, cover, and refrigerate overnight. The next morning, let them sit at room temperature for 30 minutes while the oven preheats, then bake.
- For extra gooey rolls, pour 2 to 3 tbsp of heavy cream over the proofed rolls just before they go into the oven. It creates a richer, more custardy texture.
- The frosting can be made up to 2 days ahead. Keep it covered in the fridge and let it soften at room temperature for 20 minutes before spreading.
Proof time varies with your kitchen temperature. Here is a rough guide:
| Kitchen Temperature | Approximate Proof Time |
|---|---|
| Cool (65°F / 18°C) | 75 to 90 minutes |
| Room temp (70 to 75°F / 21 to 24°C) | 45 to 60 minutes |
| Warm (80°F / 27°C) | 30 to 40 minutes |
Keeping Leftover Rolls Fresh
Store frosted rolls in an airtight container in the refrigerator for up to 4 days. Reheat individual rolls in the microwave for 20 to 30 seconds until warmed through and soft; a short blast revives them beautifully. They are still pleasant cold, but a few seconds of heat brings back the just-baked texture.
What to Serve With Cinnamon Rolls
These rolls are rich enough to stand alone, but a tall glass of cold milk or a cup of strong black coffee cuts through the sweetness perfectly. For a brunch spread, add a bowl of fresh berries and a side of crispy bacon for a salty contrast.
Frequently Asked Questions
Can I skip the overnight rise and make them the same day?
Yes. After kneading, let the dough rise at room temperature for 1.5 to 2 hours until doubled, then roll, fill, and bake. The flavor will be milder and the dough a bit softer to handle, but the rolls will still be light and tender.
My dough did not rise much in the fridge. What happened?
A very cold fridge, weak discard, or old yeast can slow the rise, but the dough should still be puffy after 8 to 24 hours. The commercial yeast provides insurance, so the rolls will bake up fluffy. Make sure your discard is still active and your fridge is not set below 35°F (2°C).
Can I freeze the baked rolls?
Unfrosted baked rolls freeze well. Cool them completely, wrap tightly, and freeze for up to 2 months. Thaw overnight in the fridge, then warm in a 300°F oven for 10 minutes and frost while warm.
Can I use bread flour instead of all-purpose?
Yes. Bread flour will give the rolls a slightly chewier crumb because of the higher protein content. All-purpose flour keeps them more tender and is preferred for softer rolls.
