southern sourdough cinnamon rolls fresh from the oven with gooey cinnamon sugar filling and shiny glaze

Sourdough Cinnamon Rolls Recipe (Soft, Tangy Perfect for Breakfast!)

I still remember the first time I made cinnamon rolls with my sourdough starter. It was a chilly Sunday morning, the kind where you keep your slippers on just a little bit longer. My kitchen smelled like sweet cinnamon and butter even before the rolls hit the oven. My grandma used to say, “Ain’t nothin’ better than a house that smells like love,” and darlin’, she was right. 

These sourdough cinnamon rolls are soft, fluffy, and have just the right balance of sweetness and tang. The sourdough starter gives them that little Southern-style twang that makes every bite extra special. If you’ve got a bubbly, happy starter on your counter, it’s time to put it to work. So grab your apron, turn on a little music, and let’s get to bakin’!

Why Make Cinnamon Rolls with Sourdough Starter?

Sourdough isn’t just for crusty loaves and artisan bread, sugar. That lovely little starter you’ve been feedin’ and lovin’ can work wonders in sweet dough, too! Using a sourdough starter for cinnamon rolls brings a few big perks:

  • Extra flavor: Natural fermentation adds a gentle tang that balances the sweetness. No bland rolls here. 
  • Soft, fluffy texture: The long, slow rise helps develop gluten and makes the dough pillowy and tender.
  • Stays fresh longer: Sourdough baked goods tend to stay soft and tasty for a couple of days (if they last that long!).
  • Great way to use discard or fed starter: This recipe uses active, bubbly starter, but it’s also a smart way to keep your starter busy.
These Southern sourdough cinnamon rolls are perfect for weekend brunch, holiday mornings, or anytime you want your kitchen to smell like a hug.

Ingredients for Sourdough Cinnamon Rolls

Here’s everything you’ll need to make these sweet, tangy rolls from scratch. 

For the Dough

For the Cinnamon Filling

  • 1/2 cup (100g) brown sugar
  • 1 tbsp ground cinnamon
  • 4 tbsp (56g) unsalted butter, softened

For the Vanilla Icing

  • 1 cup (120g) powdered sugar
  • 2 tbsp milk
  • 1/2 tsp vanilla extract

Yield: 8–10 big, bakery-style sourdough cinnamon rolls.

Step-by-Step: How to Make Sourdough Cinnamon Rolls

1. Make the Tangy Sourdough Dough

  1. Mix it up: In a large mixing bowl, whisk together the sourdough starter, warm milk, granulated sugar, melted butter, and egg until smooth and well combined.
  2. Add the dry ingredients: Gradually add the flour and salt, stirring with a spatula or wooden spoon until a shaggy dough forms. It will look a little messy at first, and that’s just fine.
  3. Knead the dough: Turn the dough out onto a lightly floured surface. Knead for about 8–10 minutes, until the dough is smooth, elastic, and just slightly sticky. If it’s very sticky, sprinkle in a little more flour, a tablespoon at a time.
  4. First rise (overnight): Place the dough in a greased bowl, turning it once to coat. Cover tightly with plastic wrap or a damp towel and let it rise at room temperature for 8–12 hours, or until doubled in size. This slow rise is where the sourdough magic happens and builds that beautiful tang. 

2. Roll, Fill & Shape the Cinnamon Rolls

  1. Roll it out: Gently deflate the risen dough and turn it onto a lightly floured surface. Roll it into a rectangle about 1/4-inch thick. Aim for a shape roughly 12x16 inches, but no need to be perfect.
  2. Spread the love: Using a spatula or butter knife, slather the softened butter evenly over the surface of the dough, right up to the edges.
  3. Add the cinnamon sugar: In a small bowl, stir together the brown sugar and cinnamon. Sprinkle this mixture evenly over the buttered dough, covering every corner so each roll is full of flavor.
  4. Roll it up: Starting from one long side, roll the dough into a snug log. Try to keep the roll tight so your cinnamon swirls are pretty and even.
  5. Slice the rolls: Use a sharp knife or unflavored dental floss to cut the log into 8–10 equal rolls. Place each roll, swirl-side up, into a buttered baking dish, leaving just a little space between them to rise.

3. Final Proof & Baking

  1. Final rise: Cover the baking dish loosely with plastic wrap or a clean kitchen towel. Let the rolls rise for about 2 hours at room temperature, or until they look puffy and are just about touching each other.
  2. Preheat the oven: When the rolls are almost ready, preheat your oven to 375°F (190°C).
  3. Bake to perfection: Bake the sourdough cinnamon rolls for 20–25 minutes, or until the tops are lightly golden brown and your kitchen smells like pure heaven. If they’re browning too quickly, you can loosely tent the pan with foil for the last few minutes.

Simple Vanilla Icing for Sourdough Cinnamon Rolls

  1. Mix the icing: In a small bowl, whisk together the powdered sugar, milk, and vanilla extract until smooth and pourable. If it’s too thick, add a tiny splash more milk; if it’s too thin, add a little more powdered sugar.
  2. Drizzle & enjoy: Let the rolls cool for about 5–10 minutes, then drizzle the icing generously over the warm rolls. Serve right away and enjoy every sticky, gooey, tangy-sweet bite. 

Tips for Perfect Sourdough Starter Cinnamon Rolls

  • Use active starter: Your sourdough starter should be bubbly and recently fed for the best rise.
  • Adjust flour if needed: Humidity and flour brands vary. If the dough is very sticky, add a touch more flour; if it’s dry, add a teaspoon of milk.
  • Overnight timing: If your kitchen is very warm, the dough may double faster. You can move it to a cooler spot if needed.
  • Make ahead: You can shape the rolls, cover the pan, and place them in the fridge overnight. Let them come to room temperature and finish proofing before baking.

How to Serve & Store Sourdough Cinnamon Rolls

These sourdough starter cinnamon rolls are best served warm, fresh from the oven with icing dripping down the sides. Pair them with hot coffee, sweet tea, or a cold glass of milk for a true Southern-style treat. 

Storing

  • Room temperature: Keep leftover rolls in an airtight container at room temperature for up to 2 days.
  • Refrigerator: For slightly longer storage (3–4 days), store in the fridge and reheat before serving.
  • Freezer: Freeze baked, un-iced rolls for up to 2 months. Thaw, warm in the oven, and drizzle with fresh icing.

Reheating

  • Microwave: Warm a single roll for 15–20 seconds, just until soft.
  • Oven: Cover the pan with foil and warm at 300°F (150°C) for about 10 minutes.

Frequently Asked Questions

Can I use sourdough discard for these cinnamon rolls?

This recipe is written for active sourdough starter so the rolls rise properly. If you want to use discard, you’ll need to add commercial yeast to help with the rise and adjust the liquid slightly.

Do sourdough cinnamon rolls taste very sour?

Nope, sugar. These sourdough cinnamon rolls have a gentle tang, not a strong sour flavor. The brown sugar, cinnamon, and icing keep them sweet and cozy, with just a little extra depth from the fermentation.

Can I make these overnight sourdough cinnamon rolls?

Absolutely! Let the dough rise overnight, shape the rolls in the morning, and give them time for their second rise. Or shape them the night before, refrigerate, and bring them back to room temperature before baking.

Sweet, Tangy & Southern-Approved

These sourdough starter cinnamon rolls are the perfect way to start your morning (or end your night—we don’t judge here!). They’re soft, fluffy, sticky, and just a little tangy in all the right ways. If your sourdough starter has been sittin’ there waitin’ for its moment to shine, this is it, darlin’.

So don’t let that starter just sit there—put it to work and fill your house with the smell of love, cinnamon, and butter. Once you try these Southern sourdough cinnamon rolls, they just might become your new family tradition.
