What Is Sourdough Discard?

Sourdough discard is the portion of sourdough starter removed before feeding it with fresh flour and water.

Although it’s called discard, it doesn’t have to go to waste!

You can use it in pancakes, muffins, biscuits, crackers, and delicious baked goods like these cinnamon rolls.

In this recipe, sourdough discard adds a subtle tangy flavor that balances the sweetness of the cinnamon filling and frosting.

Because we’re using instant yeast, the discard is primarily included for flavor rather than as the main leavening ingredient.

For consistent results, use a healthy, unfed sourdough starter at approximately 100% hydration.

Ingredients You’ll Need

For the Soft Cinnamon Roll Dough

• 3 cups (360 g) all-purpose flour: Creates the structure for soft, tender rolls.
• 1 cup (200 g) sourdough discard: Adds flavor and moisture.
• ¾ cup (180 ml) warm milk: Helps create a soft dough.
• ¼ cup (50 g) granulated sugar: Adds sweetness.
• 4 tablespoons (57 g) melted butter: Makes the rolls rich and tender.
• 1 large egg: Adds richness and structure.
• 2¼ teaspoons instant yeast: Helps the dough rise quickly.
• 1 teaspoon salt: Balances the sweetness and strengthens the dough.

For the Cinnamon Sugar Filling

• 6 tablespoons (85 g) softened butter
• ½ cup (100 g) packed brown sugar
• 1 tablespoon ground cinnamon

For the Cream Cheese Frosting

• 4 oz (115 g) softened cream cheese
• 4 tablespoons (57 g) softened butter
• 1 cup (120 g) powdered sugar
• 1 teaspoon vanilla extract
• 1–2 tablespoons milk

How to Make Sourdough Discard Cinnamon Rolls

Step 1: Prepare the Dough

In a large mixing bowl, combine the flour, sourdough discard, warm milk, sugar, melted butter, egg, instant yeast, and salt.

Mix until a shaggy dough forms.

Knead by hand or using a stand mixer with a dough hook for approximately eight minutes, until the dough becomes smooth, elastic, and slightly tacky.

Avoid adding too much extra flour, as this can make the finished rolls dry.

Step 2: Let the Dough Rise

Transfer the dough to a lightly greased bowl and cover it with a clean kitchen towel or plastic wrap.

Allow it to rise in a warm place for approximately 1–1½ hours, or until noticeably puffy and nearly doubled in size.

Rising time may vary depending on your kitchen temperature.

Step 3: Prepare the Cinnamon Filling

In a small bowl, combine the brown sugar and ground cinnamon.

Make sure the butter is softened and easily spreadable.

Step 4: Roll Out the Dough

Transfer the risen dough to a lightly floured work surface.

Using a rolling pin, roll it into a rectangle approximately 12 × 16 inches.

Spread the softened butter evenly across the dough, leaving a small border along one long edge.

Sprinkle the cinnamon sugar mixture evenly over the butter.

Step 5: Shape the Cinnamon Rolls

Starting from the long edge, roll the dough tightly into a log.

Using a sharp knife or unflavored dental floss, divide the log into nine equal pieces.

Arrange the rolls in a greased 9-inch baking pan, leaving enough room for them to expand.

Step 6: Second Rise

Cover the pan and let the rolls rise for another 45–60 minutes.

They should become visibly puffy and begin filling the spaces between them.

Don’t skip this step! The second rise is important for achieving soft, fluffy cinnamon rolls.

Step 7: Bake Until Golden

Preheat your oven to 350°F (180°C).

Bake the cinnamon rolls for approximately 22–28 minutes, until the tops are lightly golden and the centers are fully baked.

If the tops brown too quickly, loosely cover the pan with aluminum foil.

Step 8: Make the Cream Cheese Frosting

While the cinnamon rolls bake, beat the softened cream cheese and butter until smooth.

Add the powdered sugar, vanilla extract, and one tablespoon of milk.

Continue mixing until creamy, adding the remaining milk if needed.

Step 9: Frost and Enjoy

Allow the baked cinnamon rolls to cool for approximately 5–10 minutes.

Spread the cream cheese frosting generously over the warm rolls.

The frosting will soften and melt slightly into the cinnamon swirls, creating that irresistible bakery-style finish.

Serve warm and enjoy!

Tips for Perfect Homemade Cinnamon Rolls

Use warm, not hot milk. Milk that’s too hot can damage the yeast. Aim for approximately 100–110°F.

Don’t add too much flour. The dough should feel slightly tacky. Excess flour can make the rolls dense.

Use softened butter for the filling. Melted butter can run out of the dough while rolling.

Cut with dental floss. Unflavored dental floss helps create neat slices without flattening the delicate swirls.

Allow enough rising time. Watch the dough rather than relying only on the clock.

Avoid overbaking. Remove the rolls once they’re golden and baked through to keep them soft.

How to Store and Reheat Cinnamon Rolls

Because these rolls contain cream cheese frosting, store leftovers in an airtight container in the refrigerator for up to four days.

To reheat, microwave an individual roll for approximately 15–20 seconds, or until warm.

For longer storage, freeze unfrosted baked cinnamon rolls in an airtight container for up to two months.

Thaw overnight in the refrigerator, warm gently, and add freshly prepared frosting before serving.

Frequently Asked Questions

Can I use cold sourdough discard?

Yes! Sourdough discard straight from the refrigerator works well. The dough may take slightly longer to rise if the ingredients are cold.

Do I need an active sourdough starter?

No. This recipe uses instant yeast, so unfed sourdough discard works perfectly.

Can I make these cinnamon rolls overnight?

Yes. After shaping the rolls, cover the pan and refrigerate overnight. The following morning, let the rolls sit at room temperature until puffy before baking.

Why are my cinnamon rolls dense?

Dense rolls are often caused by insufficient rising time, too much flour, or under-kneaded dough. Allow both rises to finish properly.

Can I make these without instant yeast?

You can make naturally leavened sourdough cinnamon rolls, but you’ll need a different fermentation schedule and an active starter rather than relying on this quick-rise recipe.
