Soft, chewy, and rolled in the perfect mix of cinnamon and sugar — these Sourdough Snickerdoodles are cozy, classic, and just a little tangy thanks to your sourdough discard. They come together quickly and make your kitchen smell amazing while they bake.

This is such a classic cookie recipe, and I can’t believe it’s taken me this long to post these sourdough snickerdoodles! They are soft, chewy, packed with cinnamon sugar sweetness, and are a fantastic way to use up sourdough starter!
These cookies do not rely on active sourdough (though you can use it–see recipe notes in the ingredients section below)–instead, we are using sourdough discard and baking soda for the leavener.
These sourdough snickerdoodles inspired my sourdough snickerdoodle cupcake recipe! These cupcakes are perfect for the holidays and birthday parties. I made them for my sister’s autumn-themed baby shower too!

Ingredients

- All-purpose flour
- Cream of tartar
- Baking soda
- Salt
- Ground cinnamon
- Salted butter, softened – alternatively, you can use unsalted butter and add an additional 1/4 teaspoon of salt to the cookie dough.
- Granulated sugar
- Sourdough discard (unfed) – alternatively, you can use active, bubbly starter. If you’d like it fermented, make the cookie dough and stick it in the fridge overnight to ferment. Take the cookie dough out and let it sit at room temperature for about 30 minutes before scooping and baking.
- Egg yolk – one egg yolk is needed–this adds the chewiness.
- Large egg
- Vanilla extract
- Granulated sugar (for coating)
- Ground cinnamon (for coating)
Step-By-Step Instructions

Preheat your oven to 375°F (190°C) and line two baking sheets with parchment paper or silicone baking mats.
In a medium bowl, whisk together the flour, cream of tartar, baking soda, salt, and cinnamon. Set aside.

In a large mixing bowl, beat the softened butter and granulated sugar with a hand or stand mixer until light and fluffy — about 2–3 minutes.
Mix in the sourdough discard, egg yolk, egg, and vanilla extract. Beat until smooth and creamy, scraping down the sides of the bowl as needed.

Gradually add the dry ingredients to the wet mixture. Mix on low speed until just combined — the dough will be soft and slightly sticky.
In a small bowl, stir together the sugar and cinnamon for rolling.
Scoop about 2 tablespoons of dough per cookie. Roll each dough ball in the cinnamon-sugar mixture until evenly coated, then place on your prepared baking sheet about 2 inches apart.
Bake for 9–11 minutes, until the edges are set but the centers still look soft. The cookies will finish baking on the sheet as they cool.
Let the cookies cool on the pan for 5 minutes, then transfer them to a wire rack to cool completely. This recipe makes about 30 cookies!

Tips for the BEST Sourdough Snickerdoodles
- For soft and chewy centers, pull them from the oven when the middle still looks a little underbaked.
- If your sourdough discard is very runny, chill the dough for 30 minutes before rolling.
- Add a sprinkle of flaky sea salt on top for a sweet-salty touch that elevates the flavor.
