Sourdough Discard Cinnamon Rolls From Scratch
If you have sourdough discard sitting in your refrigerator, these Sourdough Discard Cinnamon Rolls are one of the best ways to use it. They are soft, fluffy, buttery, and filled with a generous layer of cinnamon sugar. Finished with a smooth cream cheese glaze, these homemade cinnamon rolls make an irresistible breakfast, brunch, or sweet afternoon treat.
Unlike traditional sourdough cinnamon rolls that rely entirely on an active starter for leavening, this discard version uses sourdough discard for flavor and texture along with instant yeast for dependable rising. That means you can enjoy deliciously soft cinnamon rolls without waiting for the discard to become active.
The sourdough discard adds a subtle tang that balances the sweetness of the brown sugar and cinnamon. The result is a tender, bakery-style cinnamon roll with a wonderfully soft center and golden edges.
Why You’ll Love These Sourdough Discard Cinnamon Rolls
These cinnamon rolls are simple enough for a beginner but special enough for a weekend breakfast.
The dough is enriched with butter, milk, egg, and sugar, which gives the finished rolls their soft and tender texture. Sourdough discard adds extra depth of flavor while helping create a beautifully rich dough.
The filling is made with softened butter, brown sugar, and cinnamon. As the rolls bake, the butter melts into the cinnamon sugar, creating a deliciously sticky and aromatic center.
A creamy glaze completes the rolls while they are still slightly warm, allowing it to melt into all those soft layers.
Best of all, this recipe is an excellent way to use leftover sourdough discard instead of throwing it away.

- 3/4 cup packed brown sugar
- 2 tablespoons ground cinnamon
- 1 teaspoon vanilla extract

What Kind of Sourdough Discard Should You Use?
You can use unfed sourdough discard that has been stored in the refrigerator. It does not need to be bubbly or recently fed because the recipe uses instant yeast to help the dough rise.
For the best flavor, use discard that has a pleasant sourdough aroma. If your discard has been stored for a while and has developed a layer of liquid on top, simply stir it back into the discard before measuring.
Avoid using discard that has an unpleasant or unusual smell or shows signs of mold.
How to Make Sourdough Discard Cinnamon Rolls
Step 1: Warm the Milk
Begin by gently warming the milk.
It should feel warm but not hot. Very hot milk can interfere with the yeast, while milk that is too cold may slow the rising process.
Pour the warm milk into a large mixing bowl.
Add the instant yeast and granulated sugar. Stir gently and allow the mixture to sit for a few minutes.
Step 2: Add the Wet Ingredients
Add the sourdough discard, egg, and melted butter to the milk mixture.
Whisk or stir until the ingredients are reasonably well combined.
The mixture may look slightly uneven because sourdough discard can vary in thickness. That is perfectly fine.
Step 3: Add the Flour and Salt
Add about 3 1/2 cups of flour and the salt.
Mix with a wooden spoon or sturdy spatula until a soft dough begins to form.
If the dough is extremely sticky, gradually add more flour, a tablespoon or two at a time.
Try not to add too much flour. Cinnamon roll dough should be soft and slightly tacky rather than stiff and dry.
Step 4: Knead the Dough
Transfer the dough to a lightly floured surface.
Knead for approximately 8–10 minutes, either by hand or using a stand mixer fitted with a dough hook.
The dough should gradually become smoother and more elastic.
When properly kneaded, it should feel soft and supple. A small amount of stickiness is normal.
Shape the dough into a ball and place it into a lightly greased bowl.
Step 5: Let the Dough Rise
Cover the bowl with plastic wrap, a lid, or a clean kitchen towel.
Place it somewhere warm and allow the dough to rise until it becomes noticeably puffy and approximately doubles in size.
This may take around 1–2 hours depending on the temperature of your kitchen.
Do not rely only on the clock. The dough should look visibly expanded before moving on to the next step.
Prepare the Cinnamon Filling
While the dough is rising, prepare the filling.
In a small bowl, combine the brown sugar, cinnamon, vanilla, and pinch of salt.
Keep the softened butter separate or mix it into the cinnamon sugar if you prefer a spreadable filling.
The butter should be soft enough to spread easily but not completely melted.
Step 6: Roll Out the Dough
Once the dough has doubled in size, gently punch it down to release excess air.
Transfer it to a lightly floured work surface.
Roll the dough into a large rectangle, approximately 14 × 18 inches.
Try to keep the thickness relatively even from edge to edge.
Step 7: Add the Cinnamon Filling
Spread the softened butter evenly over the surface of the dough.
Leave a small border around the edges so the filling does not squeeze out excessively when you roll it.
Sprinkle the brown sugar and cinnamon mixture evenly over the butter.
Make sure the filling reaches nearly every part of the dough for maximum cinnamon flavor in every roll.
Step 8: Roll the Dough
Starting from one long side, carefully roll the dough into a tight log.
Try to keep the roll even as you work from one end to the other.
Do not roll so tightly that you crush the layers, but make sure there are no large gaps between the layers.
Once rolled, pinch the seam gently to help keep the log closed.
Step 9: Cut the Cinnamon Rolls
Use a sharp knife or unflavored dental floss to divide the log into approximately 10–12 equal pieces.
Dental floss is especially useful because it can cut through the dough without flattening the rolls.
Arrange the rolls in a greased 9 × 13-inch baking dish.
Leave a little space between them because they will expand during the second rise.
Step 10: Second Rise
Cover the baking dish and allow the rolls to rise again for approximately 30–60 minutes.
They should become visibly puffy and begin to touch one another.
This second rise is important for creating soft and fluffy cinnamon rolls.
Avoid baking them before they have had enough time to become light and airy.
Step 11: Bake the Cinnamon Rolls
Preheat your oven to 350°F (175°C).
Place the risen cinnamon rolls in the oven and bake for approximately 22–28 minutes.
The tops should become lightly golden brown, while the centers should look cooked but remain soft.
Avoid overbaking the rolls because too much oven time can make them dry.
If the tops begin browning too quickly, loosely cover the baking dish with foil for the remaining baking time.
Make the Cream Cheese Glaze
While the cinnamon rolls are baking, prepare the glaze.
Add softened cream cheese and butter to a bowl.
Beat until smooth and creamy.
Add the powdered sugar and vanilla extract and mix again until combined.
Gradually add milk, a little at a time, until the glaze reaches your preferred consistency.
For a thicker frosting, use less milk. For a thinner drizzle, add slightly more.
Step 12: Glaze the Warm Rolls
Remove the cinnamon rolls from the oven and let them cool for a few minutes.
Spread the cream cheese glaze over the warm rolls.
The warmth of the cinnamon rolls will soften the glaze slightly and allow it to melt into the layers.
For extra indulgence, serve the rolls while they are still warm.
Tips for Soft and Fluffy Cinnamon Rolls
Don’t Add Too Much Flour
One of the biggest mistakes when making cinnamon rolls is adding too much flour.
A dough that feels slightly sticky is often preferable to a dry, stiff dough. Excess flour can result in heavy cinnamon rolls.
Add flour gradually and stop when the dough becomes soft, smooth, and manageable.
Use Soft Butter for the Filling
The butter should be soft enough to spread across the dough.
If it is melted and watery, it may leak out of the dough while rolling.
Softened butter creates an even layer that helps hold the cinnamon sugar in place.
Give the Dough Enough Time to Rise
The rising time can vary depending on your kitchen temperature.
A warm environment will usually speed up fermentation, while a cooler room can require additional time.
Look for visual signs rather than following the timer blindly.
Don’t Overbake
Soft cinnamon rolls should have lightly golden tops and tender centers.
Overbaking can remove too much moisture and leave you with dry rolls.
Start checking toward the end of the recommended baking time.
Use a Sharp Knife or Dental Floss
A dull knife can squash the cinnamon roll log.
Unflavored dental floss is an excellent way to cut clean, round pieces without compressing the layers.
Optional Overnight Method
These cinnamon rolls can also be prepared ahead of time.
After cutting the rolls and placing them into the baking dish, cover them tightly and refrigerate overnight.
The following morning, remove them from the refrigerator and allow them to sit at room temperature until they become puffy.
Then bake according to the recipe.
This method is especially convenient for weekend breakfasts, holidays, and special occasions because most of the preparation can be completed the night before.
How to Store Cinnamon Rolls
Store leftover cinnamon rolls in an airtight container at room temperature for a short period or refrigerate them if they are heavily coated with cream cheese frosting.
They can be gently reheated in the microwave for a few seconds to restore their soft texture.
For longer storage, freeze the baked cinnamon rolls without the glaze.
Wrap them individually or place them in a freezer-safe container.
When ready to enjoy, thaw and warm them before adding fresh cream cheese glaze.
Frequently Asked Questions
Can I use sourdough discard straight from the refrigerator?
Yes. Cold discard can be used, although allowing it to warm slightly can make it easier to mix with the other ingredients.
Does the discard need to be active?
No. This recipe uses instant yeast for leavening, so the discard does not need to be active or bubbly.
Can I make these without cream cheese frosting?
Absolutely. The rolls are delicious with a simple powdered sugar glaze, vanilla icing, or even just a little melted butter.
Why are my cinnamon rolls dense?
Dense rolls can result from too much flour, insufficient rising time, inactive yeast, or a dough that was handled too aggressively.
Make sure the dough becomes noticeably puffy during both rises.
Can I freeze sourdough discard cinnamon rolls?
Yes. Baked rolls can be frozen for longer storage. For best results, freeze them without the cream cheese glaze and add fresh frosting after reheating.
