They’re soft in the middle, slightly crisp at the edges, and coated in a cinnamon-sugar crust that cracks just right. The sourdough starter adds a gentle tang and keeps the cookies tender.

No fancy tools needed—just a bowl, a whisk, and a little time to chill the dough. This is the kind of bake that makes your kitchen smell like a warm hug.

Why This Recipe Works

Close-up detail: Freshly baked sourdough snickerdoodles cooling on parchment, edges set with fine go

Snickerdoodles are known for their chewy centers and signature cinnamon-sugar shell. The sourdough twist gives them a subtle tang that balances the sweetness without turning them into “sourdough-flavored” cookies.

Using both baking soda and cream of tartar creates that classic lift and soft texture. A short chill keeps the cookies from spreading too much and helps the flavors mingle. Butter at the right temperature and a careful mix ensure the cookies bake up tender, not tough.

What You’ll Need

Unsalted butter (room temperature) – for richness and structure
Granulated sugar – for sweetness and crisp edges
Brown sugar – adds moisture and a hint of caramel
Egg – binds and adds tenderness
Sourdough starter (100% hydration, discard or active) – for tang and moisture
Vanilla extract – warmth and aroma
All-purpose flour – the base of the dough
Cream of tartar – classic snickerdoodle ingredient for tang and texture
Baking soda – lift
Fine sea salt – balances sweetness
Cinnamon – in the coating and a pinch in the dough (optional)
Coating: granulated sugar + ground cinnamon

How to Make It

Prep your basics. Line two baking sheets with parchment.
Set butter out until slightly soft to the touch. If your kitchen is hot, chill your bowl for a few minutes so the dough doesn’t get greasy.
Make the cinnamon-sugar. In a small bowl, mix 1/3 cup granulated sugar with 1–1.5 teaspoons cinnamon. Set aside for rolling.
Cream the butter and sugars. In a large bowl, beat 1/2 cup unsalted butter with 1/2 cup granulated sugar and 1/3 cup brown sugar until light and fluffy, about 2–3 minutes.
This traps air for a softer cookie.
Add egg, vanilla, and starter. Beat in 1 large egg and 1 teaspoon vanilla until smooth. Mix in 1/2 cup sourdough starter (discard or active). The batter may look slightly curdled—that’s okay.
Whisk dry ingredients. In a separate bowl, whisk 1 3/4 cups all-purpose flour, 1 1/2 teaspoons cream of tartar, 1/2 teaspoon baking soda, 1/2 teaspoon fine sea salt, and a small pinch of cinnamon if using.
Combine gently. Add dry ingredients to the wet mixture.
Stir with a spatula just until no dry streaks remain. Do not overmix or the cookies can turn tough.
Chill the dough. Cover and refrigerate 30–45 minutes. This helps the dough firm up, intensifies flavor, and controls spread.
Preheat and portion. Heat oven to 350°F (175°C). Scoop dough into 1.5-tablespoon balls (about 30 g each).
Roll each ball in the cinnamon-sugar mixture until fully coated.
Bake. Place on prepared sheets, spacing 2 inches apart. Bake 9–11 minutes, until edges are set and centers still look slightly soft. The cookies will puff, then collapse slightly as they cool, creating that signature crinkle.
Cool and set. Let cookies rest on the sheet for 5 minutes, then transfer to a rack to finish cooling.
They’ll firm up as they cool, staying chewy in the middle.

Storage Instructions

Room temperature: Store in an airtight container for 3–4 days. Slip in a small piece of bread or a marshmallow to keep them soft.
Freezer (baked): Freeze cooled cookies in a zip-top bag for up to 2 months. Thaw at room temperature.
Freezer (unbaked): Freeze dough balls (already rolled in cinnamon sugar) on a sheet until solid, then bag.
Bake from frozen at 350°F (175°C), adding 1–2 minutes.

Why This is Good for You

These are cookies, so they’re a treat—but the sourdough starter adds a few perks. The natural acidity can make the cookies easier on your stomach than some standard cookies. It also adds moisture without extra fat, so you get a soft texture with balanced sweetness.

And if you bake often, using starter discard helps cut down on food waste, which is good for your pantry and the planet.

What Not to Do

Don’t skip the chill. Warm dough spreads too much and bakes up thin and greasy.
Don’t overbake. Pull them when the centers still look a little puffy and soft. They finish on the sheet.
Don’t overmix the flour. Stir just until combined to avoid tough, cakey cookies.
Don’t use cold butter. It won’t cream properly, and your texture will suffer.
Don’t pack the flour. Spoon and level it, or weigh it, to keep the dough tender.

Recipe Variations

Brown Butter Sourdough Snickerdoodles: Brown the butter, cool until just solid, then cream as directed. This adds a nutty, toffee note.
Chai Snickerdoodles: Mix cardamom, ginger, and a pinch of black pepper into the cinnamon-sugar coating for a cozy spice blend.
Lemon-Twist Snickerdoodles: Add 1–2 teaspoons lemon zest to the dough.
The citrus brightens the sourdough tang.
Extra Chewy: Swap 2 tablespoons of flour for 2 tablespoons cornstarch, and slightly underbake for ultra-soft centers.
Gluten-Free: Use a 1:1 gluten-free flour blend with xanthan gum, and chill the dough on the longer side (45–60 minutes) to help it set.
Cinnamon-Plus Sugar: Coat twice—once before baking and once immediately after they come out—for a thicker crust.

FAQ

Can I use sourdough discard instead of active starter?

Yes. Discard works perfectly here because you’re not relying on the starter for rise. It adds tang and moisture either way, so use whatever you have on hand.

Do I really need cream of tartar?

For classic snickerdoodle taste and texture, yes.

It brings that subtle tang and helps the cookies stay soft. If you must substitute, use 2 teaspoons baking powder in place of the cream of tartar and baking soda combined, but expect a slightly different flavor.

Why are my cookies flat?

Likely warm dough or too little flour. Chill longer and make sure you measured flour correctly.

Also check that your butter wasn’t melted and your oven is truly at 350°F.

Can I make the dough ahead?

Absolutely. Chill the dough up to 24 hours, tightly covered. If it firms up a lot, let it sit at room temperature for 10–15 minutes so it’s scoopable.

How do I get thicker cookies?

Use slightly cooler dough, make larger scoops, and bake on a cool, light-colored sheet.

You can also add 1–2 extra tablespoons of flour to stiffen the dough a bit.

Can I reduce the sugar?

You can cut the sugar in the dough by about 2–3 tablespoons without major texture changes. Keep the full cinnamon-sugar coating for the signature crust.

What if I don’t have brown sugar?

Use all granulated sugar and add 1 teaspoon of molasses if you have it. If not, all white sugar will still work—your cookies will be slightly crisper.

Do I need to press the dough balls down?

No.

They spread on their own. If you like a slightly thinner cookie, you can give each ball a gentle press before baking.

How do I know when they’re done?

Edges should be set and lightly golden, and the centers should look puffy and soft. If they look fully dry in the middle, they’re likely overbaked.

Final Thoughts

Sourdough Snickerdoodles take everything you love about the classic and give it a little glow-up.

The tang from the starter makes the sweetness pop, and the cinnamon-sugar crust seals the deal. They’re simple, cozy, and perfect for anytime baking. Keep a jar of starter in the fridge, and you’re always just a short chill away from a warm tray of cookies.

Enjoy them with coffee, tea, or a cold glass of milk—no wrong answers here.
