Best Cinnamon Sourdough Muffins (Soft, Warm & Easy!)
If your sourdough starter has been sitting in the fridge collecting discard, this is the recipe you have been waiting for. These Cinnamon Sourdough Muffins turn that tangy, bubbly leftover starter into something genuinely magical: tender, warmly spiced muffins with a crackly cinnamon sugar top and a pillowy crumb that practically melts on your tongue. Whether you are a seasoned sourdough baker or just getting started, this sour dough muffin recipe is one of those keepers you will come back to every single week.
The secret is the combination of sourdough discard and a generous hand with cinnamon. The discard adds a subtle tang that balances beautifully against the sweetness, while the cinnamon weaves through every bite like the best kind of cinnamon breakfast you can imagine. These are the muffins that make people lean over their coffee mugs and ask, “Wait, what is in these?”
What Makes This Recipe Special
- Zero-waste baking: This recipe is built around sourdough discard muffins, giving your leftover starter a delicious purpose instead of tossing it down the drain.
- Unbeatable texture: The discard keeps the crumb moist and tender far longer than a standard muffin, so these stay soft even on day two.
- Big cinnamon flavor: A double hit of cinnamon, in the batter and on top as a cinnamon sugar crust, means every bite delivers that warm, cozy spice you crave.
- Weekday friendly: You can mix these together in about fifteen minutes, making them a realistic cinnamon breakfast option even on busy mornings.
Key Ingredients
- Sourdough discard (1 cup): The star ingredient. Unfed discard works perfectly here and adds that gentle tang that sets these apart from ordinary cinnamon sugar muffins.
- All-purpose flour (1.75 cups): Gives the muffins structure without making them dense. Spoon and level for accuracy.
- Granulated sugar (0.5 cup): Sweetens the batter and, combined with cinnamon on top, creates that irresistible crunchy crown.
- Brown sugar (0.25 cup): Adds a hint of molasses depth that complements the cinnamon sourdough flavor beautifully.
- Ground cinnamon (2.5 tsp total): Use 1.5 tsp in the batter and 1 tsp mixed with sugar for the topping.
- Eggs (2 large): Provide richness and help bind everything together.
- Unsalted butter (0.5 cup, melted): Keeps the crumb tender and adds a buttery richness that makes these feel indulgent.
- Whole milk (0.25 cup): Loosens the batter slightly for a smooth, scoopable consistency.
- Baking powder (1.5 tsp): The primary leavener that gives the muffins their lift.
- Baking soda (0.25 tsp): Reacts with the acidity in the discard for an extra boost of rise.
- Vanilla extract (1 tsp): Rounds out the spice and sweetness with a warm background note.
- Salt (0.5 tsp): Balances the sugar and enhances every other flavor in the muffin.
Using quality tools makes a real difference in how evenly these bake and how easy cleanup is. From a reliable muffin tin to a sturdy mixing bowl, the right equipment keeps the process smooth from start to finish.

Cinnamon Sourdough Muffins
Equipment
- 12-cup standard muffin tin
- Large mixing bowl
- Medium mixing bowl
- Rubber spatula
- Wire cooling rack
Ingredients
Muffin Batter
- 1.75 cups all-purpose flour spooned and leveled
- 1.5 tsp ground cinnamon for batter
- 1.5 tsp baking powder
- 0.25 tsp baking soda
- 0.5 tsp salt
- 0.5 cup unsalted butter melted and slightly cooled
- 0.5 cup granulated sugar
- 0.25 cup brown sugar packed
- 2 large eggs room temperature
- 1 cup sourdough discard unfed, room temperature
- 0.25 cup whole milk room temperature
- 1 tsp vanilla extract
Cinnamon Sugar Topping
- 2 tbsp granulated sugar
- 1 tsp ground cinnamon
Instructions
- Preheat your oven to 400°F (200°C). Line a 12-cup standard muffin tin with paper liners or grease each cup well with butter or nonstick spray.
- In a large mixing bowl, whisk together the flour, 1.5 teaspoons cinnamon, baking powder, baking soda, and salt until evenly combined and no lumps remain.
- In a medium bowl, whisk the melted butter with the granulated sugar and brown sugar until smooth. Add the eggs one at a time, whisking well after each addition. Stir in the sourdough discard, milk, and vanilla extract until the mixture is uniform.
- Pour the wet ingredients into the dry ingredients and fold gently with a rubber spatula just until no dry streaks remain. A few small lumps are fine. Do not overmix or the muffins will turn out tough and dense.
- Divide the batter evenly among the prepared muffin cups, filling each about three-quarters full.
- In a small bowl, mix together the 2 tablespoons of granulated sugar and 1 teaspoon of cinnamon for the topping. Sprinkle generously over each muffin.
- Bake at 400°F for 5 minutes, then without opening the oven door reduce the temperature to 375°F (190°C) and continue baking for 14 to 16 more minutes, until the tops are golden and a toothpick inserted in the center of a muffin comes out clean.
- Allow the muffins to cool in the pan for 5 minutes, then transfer to a wire rack. Serve warm or at room temperature.
Notes
Make It Your Own
- Add-ins: Fold in 0.5 cup of chopped walnuts, pecans, or raisins for extra texture and flavor in your sourdough muffins.
- Apple cinnamon version: Stir in 0.75 cup of finely diced apple for a fruit-forward twist on the classic cinnamon sourdough profile.
- Dairy-free swap: Replace the butter with melted coconut oil and the milk with oat milk for a dairy-free version that still bakes up beautifully.
- Streusel topping: Instead of a simple cinnamon sugar dusting, make a quick streusel with 3 tablespoons each of flour, cold butter, and brown sugar for a bakery-style crumble top.
How to Make Cinnamon Sourdough Muffins
- Preheat and prep: Set your oven to 400°F (200°C). Line a standard 12-cup muffin tin with paper liners or grease each cup generously with butter or nonstick spray. Starting with a hot oven ensures the muffins get a good initial rise and a beautifully domed top.
- Mix the dry ingredients: In a large bowl, whisk together the flour, baking powder, baking soda, 1.5 teaspoons of cinnamon, and salt. Whisking eliminates any lumps and evenly distributes the leaveners so every muffin rises the same.
- Combine the wet ingredients: In a separate medium bowl, whisk together the melted butter, granulated sugar, and brown sugar until smooth. Add the eggs one at a time, whisking well after each. Stir in the sourdough discard, milk, and vanilla extract until the mixture looks uniform and slightly glossy.
- Fold together: Pour the wet ingredients into the dry ingredients and fold gently with a rubber spatula. Stop mixing as soon as no dry streaks remain. A few small lumps are completely fine. Overmixing is the number one cause of tough, dense sourdough muffins.
- Fill the cups: Divide the batter evenly among the prepared muffin cups, filling each about three-quarters full. Mix the remaining 1 teaspoon of cinnamon with 2 tablespoons of granulated sugar and sprinkle it generously over each muffin top.
- Bake to perfection: Bake at 400°F for 5 minutes, then reduce the oven temperature to 375°F (190°C) and continue baking for 14 to 16 more minutes. The initial high heat creates a dramatic dome. Muffins are done when a toothpick inserted in the center comes out clean and the tops are golden brown.
- Cool briefly: Let the muffins rest in the pan for 5 minutes before transferring to a wire rack. This prevents them from steaming and getting soggy on the bottom.
Tips for Best Results
- Use room-temperature ingredients: Cold eggs or cold milk can seize up the melted butter and create a lumpy batter. Pull everything out of the fridge about 20 minutes before you start.
- Do not skip the two-temperature bake: Starting at 400°F then dropping to 375°F is the trick professional bakers use to get tall, domed muffin tops. Skipping this step will give you flat, sad muffins.
- Measure your discard correctly: Spoon the discard into a measuring cup and level it off. Packing it in will throw off the moisture balance of the entire batter.
- Avoid the common overmixing mistake: Once wet meets dry, put down the whisk and pick up a spatula. Gluten develops fast, and overworked batter bakes up rubbery instead of tender.
Chef’s Tip: If your sourdough discard has been in the fridge for more than two weeks, give it a smell before using. It should smell pleasantly tangy, like yogurt or beer, not unpleasantly rancid. Very old discard can make the muffins taste overly sour.
Serving Suggestions
- Classic and simple: Serve warm with a pat of salted butter melting into the top. This is the move for a cozy cinnamon breakfast on a slow weekend morning.
- Dressed up: A drizzle of honey or maple syrup over the top turns these into something that feels like a treat without any extra effort.
- With a spread: Whipped cream cheese or apple butter pairs wonderfully with the tangy cinnamon flavor of these sourdough discard muffins.
- Alongside a drink: Serve with a latte, hot tea, or a simple glass of cold milk. The slight tang of the sourdough plays beautifully against the richness of a milky coffee.
Make Ahead and Storage
- Room temperature: Store cooled muffins in an airtight container at room temperature for up to 3 days. Place a sheet of paper towel in the container to absorb excess moisture and keep the tops from getting tacky.
- Refrigerator: These muffins keep well in the fridge for up to 5 days. They may firm up slightly when cold, so a quick warm-up before eating is recommended.
- Freezing: These freeze beautifully. Wrap each muffin individually in plastic wrap, then place them in a zip-top freezer bag. They will keep for up to 3 months.
- Reheating: Thaw overnight in the fridge or on the counter for an hour. To revive that fresh-baked warmth and texture, microwave for 20 to 30 seconds or warm in a 300°F oven for 8 minutes.
Frequently Asked Questions
Can I use active, fed starter instead of discard?
Yes, you can use active starter in this recipe. The muffins will have a slightly milder tang since fed starter is less acidic than older discard. Both work well in this sour dough muffin recipe.
Why did my muffins come out dense?
The most likely culprit is overmixing. Once you combine the wet and dry ingredients, fold just until incorporated. Dense muffins can also result from using too much discard or not enough leavener, so measure carefully.
Can I make these gluten-free?
You can substitute a 1:1 gluten-free flour blend, though the texture will be slightly different. Keep in mind that if your sourdough starter is wheat-based, the muffins will not be fully gluten-free regardless.
Can I reduce the sugar?
You can cut the granulated sugar down to 0.33 cup without significantly affecting the texture. Going lower than that may impact the moisture and browning of the muffins.
