Soft Sourdough Snickerdoodle Cookies (No Cream of Tartar!)

These soft sourdough snickerdoodle cookies have buttery, chewy centers, lightly crisp edges, and a crackly cinnamon-sugar coating in every bite. Sourdough starter supplies the signature tang, which means this recipe needs no cream of tartar, and either active starter or discard works beautifully. With no chill time required, you can enjoy warm, nostalgic snickerdoodles fresh from the oven without waiting for the dough to chill!

Essentials for the Perfect Sourdough Cookie

• Digital Kitchen Scale: Thick, chewy cookies depend on the right balance of flour, starter, and moisture. A digital kitchen scale removes the guesswork so your cookies spread properly while keeping those soft, chewy centers. I have used this exact scale in my kitchen for years, and it has never failed me!
• Stand Mixer: Properly mixing the butter and sugars creates the foundation for that soft, bakery-style texture. A quality stand mixer fitted with the paddle attachment makes quick work of this thick dough, but a handheld electric mixer works too. Just be careful not to overmix once the flour is added!
• Large Cookie Scoop: Nearly all of my sourdough cookie recipes are designed to make large, bakery-style cookies. A large cookie scoop portions the dough evenly so every cookie bakes at the same rate, giving you set edges and soft centers without some cookies becoming overdone while others remain underbaked.

Ingredients

• 1 cup light brown sugar, packed (220g): Pack it tight for the best chew and a perfect spread!
• 2 tbsp granulated sugar (25g): Balances moisture for slightly crisp edges while maintaining the chewy center.
• ½ cup salted butter, softened (113g): Use “dent soft” butter, meaning it should indent with resistance when pressed, remaining cool to the touch and not shiny or oily. This usually takes 30–60 minutes at room temperature. To use unsalted butter, add an additional ¼ tsp salt.
• ½ cup sourdough starter, active or discard, stirred down (150g): Active or discard starter works! Stir it down well before measuring by volume. For best accuracy, measure by weight.
• 2 large egg yolks (40g): Yolks only (skipping the egg white) give the cookies a chewy, soft center that is never cakey.
• 2 tsp vanilla extract (10g): Pure vanilla extract provides the cleanest, best flavor.
• 2 tsp ground cinnamon (5g): Cinnamon is vital for giving the snickerdoodle cookies their classic warm-spiced flavor.
• 1 tsp ground nutmeg (2g): This is the secret ingredient that makes these cookies taste like they came from a bakery. It adds a nutty depth that highlights the tang of the sourdough without overpowering the cinnamon.
• ½ tsp salt (3g): Sea salt is preferred over iodized salt for a cleaner flavor.
• 1½ cups all-purpose flour, scooped (not spooned or sifted) (235g): I designed this volume measurement for this recipe to be scooped directly out of the bag (not sifted or spooned and leveled). Pro Tip: For the best accuracy and overall cookie texture, measure flour by weight.
• 1 tsp baking soda (6g): Ensure you are using baking soda, not baking powder. They’re not interchangeable here.
• ¼ cup cinnamon sugar: To make this, just mix ¼ cup granulated sugar with 1½ tsp ground cinnamon in a small bowl. You’ll roll the cookie dough in this mixture to create the signature crackly cinnamon-sugar coating!

How to Make Sourdough Snickerdoodle Cookies

Step 1: Preheat Oven & Prep

Preheat oven to 350°F (175°C). Line a baking sheet with parchment paper.

Step 2: Cream the Butter & Sugars

Beat the brown sugar, granulated sugar, and softened butter until the texture is creamy, uniform, and slightly aerated. If you see chunks of butter, keep mixing! This works best with a stand mixer (paddle attachment) or a handheld electric mixer.

Step 3: Add the Wet Ingredients

Add the sourdough starter, egg yolks, vanilla extract, cinnamon, nutmeg, and salt. Beat until smooth and slightly frothy. Pro Tip: Scrape down the sides of the bowl to ensure the starter is fully incorporated with no streaks remaining.

Step 4: Incorporate the Dry Ingredients

Add the flour and sprinkle the baking soda evenly over the top. Turn the mixer to low speed and stir until just combined. Critical Step: Stop mixing as soon as the flour is mostly incorporated. A few tiny streaks are okay. Gently finish incorporating them with a spatula. Over-mixing here develops too much gluten, making cookies tough rather than chewy.

Step 5: Prepare the Cinnamon Sugar

In a shallow plate or bowl, stir together the granulated sugar and cinnamon.

Step 6: Scoop & Roll

Portion the dough into large scoops using a cookie scoop or spoon (3 tbsp / 68g each). Roll each scoop in prepared cinnamon sugar until all sides are coated generously. Place 6 of the scoops per baking sheet to allow space for spreading.

Step 7: Bake

Bake for 12–15 minutes, rotating the pan halfway through. Remove when the edges are set and slightly golden but the centers still look soft. Pro Tip: Immediately after removing the pan from the oven, firmly tap it against a heatproof surface a few times to deflate the cookies. This creates a denser, chewier texture. Bake in batches. Recipe makes about 12 cookies.

Step 8: Cool on Baking Sheet

Allow the cookies to set on the hot baking sheet for 7 minutes before transferring to a wire rack. Moving them too early may cause them to fall apart.

Storage Tips

• Store completely cooled cookies in an airtight container for up to 5 days at room temperature.
• Pro Tip: Place a slice of bread in the container to keep cookies soft. The cookies will absorb the moisture from the bread (the bread will turn hard!), preventing the spiced snickerdoodle cookies from drying out as quickly.

Why This Recipe Works

These soft sourdough snickerdoodle cookies work because every ingredient is carefully balanced to control moisture, texture, and spread. Brown sugar holds moisture in the cookies for soft, chewy centers, while a small amount of granulated sugar helps the edges set and become lightly crisp. Using egg yolks without the whites adds richness without creating a cakey texture, and the combination of properly softened “dent soft” butter, sourdough starter, and precisely measured flour allows the cookies to spread beautifully without chilling the dough.

Instead of cream of tartar, the natural acidity of the sourdough starter helps activate the baking soda while providing the signature tang expected from a snickerdoodle. Cinnamon and nutmeg flavor the dough from within, while the cinnamon-sugar coating creates a crackly, warmly spiced exterior. Tapping the pan immediately after baking helps the cookies settle, giving them beautifully crinkled tops and an even denser, chewier center.

The Sourdough Cookie Lady Tips

• Don’t skip the cinnamon sugar rolling step. Rolling these in cinnamon sugar before baking is what helps create those soft, crinkly tops with the perfect cinnamon-forward flavor!
• Do a long-fermentation if you want a tangier flavor. To get that classic and sharp bite without cream of tartar, try doing a long-fermentation on the dough to deepen the complexity and tang of the sourdough starter. If you need a no-wait dough, use sourdough discard instead of active starter to get results as tangy as possible.
• Let the butter become “dent soft.” To keep this a no-chill snickerdoodle recipe, the butter should indent easily when pressed but still feel cool and offer some resistance. It should not look melted, shiny, or oily.
• Do not overbake the cookies. Remove them when the edges are set but the centers still look soft and slightly underbaked. They will continue to firm up on the hot baking sheet, giving you that soft, chewy center instead of a dry or cakey texture.
• Use only the egg yolks. Whole eggs add too much moisture and can push the cookies toward a cakey texture. Egg yolks help keep the centers dense, soft, and chewy.
• Measure the flour and sourdough starter by weight if possible. The balance between flour and the moisture from the sourdough starter makes a big difference in the final texture. Weighing them helps prevent cookies that spread too much or turn out overly thick and dry.
• Tap the pan after baking. Tapping the pan right after baking helps deflate the centers slightly for a softer and chewier bite.

Frequently Asked Questions

Why is there no cream of tartar?

Traditional snickerdoodle cookies use cream of tartar to provide acidity, help activate the baking soda, and create their signature tang. In this recipe, the natural acidity of the sourdough starter serves that purpose, so no cream of tartar is needed! Active starter or discard both work, although sourdough discard or the optional long fermentation will provide a more noticeable tang.

What happens if the dough balls are too soft to roll in the cinnamon sugar?

If your dough balls are too soft after mixing the dough, it usually means that the dough likely became too warm while preparing it. This has to do with butter temperature, as well as the temperature of the room and how long it’s taking you to prepare the dough. If the balls are too soft to roll in cinnamon sugar, simply cover the bowl and refrigerate the dough for 20–30 minutes, or until it is firm enough to scoop and roll!

Can I use active starter instead of discard?

Absolutely! Both active starter and sourdough discard work well here. Since the baking soda handles most of the leavening, the only difference will be a slightly milder flavor when using an active, recently fed starter.

Why did my cookies come out cakey instead of chewy?

Cakey cookies are commonly caused by adding too much flour or using whole eggs instead of egg yolks. For that signature dense, chewy texture, weigh the flour in grams, use only the yolks, and remove the cookies from the oven when the edges are set but the centers still look soft. Overbaking can make the cookies dry, while overmixing after adding the flour can create a tough, bread-like crumb. Mix on low speed only until a few tiny streaks of flour remain, then gently finish incorporating them with a spatula.

Do I have to chill the dough before baking?

No, you don’t! This is a no-chill recipe, so you can bake the cookies immediately for a no-wait sourdough treat. However, if you prefer a long-fermentation option with more developed sourdough flavor, refrigerate the dough for up to 3 days. Then, before baking, let it sit at room temperature for about an hour, or until it is soft enough to scoop, to encourage the proper spread.

Can I freeze sourdough cookie dough?

Absolutely! For best results, follow this flash-freezing method:

1. Scoop: Portion the sourdough snickerdoodle cookie dough into balls (3 tbsp / 68g each) and place them on a parchment-lined baking sheet. They can be close together, but make sure they are not touching. Don’t roll them in cinnamon sugar yet. You will do that just before baking.
2. Flash Freeze: Place the sheet in the freezer for about 1 hour, or until the dough balls are firm to the touch.
3. Store: Transfer the frozen dough balls into a gallon freezer bag. They can be stored in the freezer for up to 3 months!

Pro Tip: Double the recipe and intentionally freeze an extra batch! This gives you ready-to-bake snickerdoodle sourdough cookies whenever that sweet tooth hits.

Tips For Baking Frozen Dough:

Thaw Partially: For best results, allow frozen dough to sit at room temperature for 30–60 minutes before rolling in cinnamon sugar and baking. This helps achieve a texture and baking time nearly identical to a fresh batch of dough.

Potentially Increase Bake Time: You may need to add 1–2 minutes to the baking time if the dough is still colder than fresh dough would be.

How to Make Long-Fermented Sourdough Snickerdoodle Cookies

To long-ferment the dough for deeper flavor and a slower fermentation option that some bakers prefer for digestibility, follow these simple directions:

1. Prepare: Follow the recipe directions to make the dough.
2. Cold Ferment: Cover the bowl with plastic wrap, or transfer to an airtight container. Refrigerate for 1–3 days. Note: The longer the dough ferments, the more noticeable the sourdough tang may become.
3. Bring to Room Temp: Dough temperature significantly affects how much the cookies spread. Remove the dough from the refrigerator about 1 hour before baking, or allow it to rest until it is soft enough to scoop easily.
4. Scoop, Roll, & Bake: Once the dough is soft enough to scoop, portion it into scoops (3 tbsp / 68g each), roll in cinnamon sugar, and bake according to the recipe directions!

Troubleshooting: If the cookies remain unusually thick or do not spread enough, the dough was probably still too cold when it went into the oven.
