Sourdough Chocolate Chip Cookies
I like making these sourdough chocolate chip cookies when I have an extra starter in the fridge. I usually bake them on weekends or when I want a warm snack after dinner. They are thick, soft in the middle, and full of melted chocolate with a light salty finish.
Step by Step Method
Browning the Butter
Start by placing the butter in a small saucepan over medium heat. Let it melt fully, then keep cooking while gently swirling the pan. The butter will foam first, then turn golden, and finally develop brown bits at the bottom. This is where the flavor comes from. It should smell nutty, not burnt. As soon as it reaches a deep amber color, pour it into a mixing bowl right away so it stops cooking. Let it cool until it feels warm, not hot, when you touch the outside of the bowl.
Mixing the Sugars
Add the brown sugar and granulated sugar to the warm butter. Whisk firmly until the mixture looks smooth and glossy. You want the sugars to fully blend with the butter so there are no lumps. The mixture should look thick and shiny, almost like a loose caramel.
Adding Egg and Vanilla
Crack in the egg and pour in the vanilla extract. Whisk again until everything is fully mixed. The batter should look creamy and slightly thick. If you lift the whisk, it should fall back into the bowl in ribbons.
Stirring in the Sourdough Discard
Add the sourdough discard and stir until the batter is smooth. There should be no streaks or clumps. The dough will loosen slightly at this stage, and that is normal. The discard adds moisture and helps create the soft center later.
Mixing the Dry Ingredients
Sprinkle in the flour, baking soda, and fine salt. Stir gently with a spoon instead of whisking. Mix just until the flour disappears. The dough should feel soft and thick but not dry. If it feels sticky like batter, add a small spoonful of flour at a time. Stop mixing as soon as the dough comes together so the cookies stay tender.
Folding in the Chocolate Chips
Add the chocolate chips and fold them into the dough. Turn the dough from the bottom of the bowl upward so the chips spread evenly. Every scoop should have plenty of chocolate.
Shaping the Cookies
Line a baking sheet with parchment paper. Scoop large spoonfuls of dough and stack them tall instead of flattening them. Leave space between each mound because the cookies will spread slightly. Press a few extra chocolate chips onto the tops so they stay visible after baking.
Baking the Cookies
Place the tray in a 350°F (175°C) oven. Bake for 10 to 13 minutes. The edges should turn light golden while the centers stay pale and soft. The cookies may look slightly underbaked in the middle, but they will firm up as they cool. This step is key to keeping the inside chewy.
Finishing and Cooling
Remove the tray from the oven and sprinkle flaky salt on top if using. Let the cookies rest on the pan for about 10 minutes. They will set up during this time without drying out. After that, move them to a rack to cool completely or eat them warm while the chocolate is still melted.
Why You Will Love This Recipe
These cookies are thick, soft, and easy to make with leftover sourdough discard. The browned butter gives them a warm, nutty taste that makes them feel homemade in the best way. The dough comes together in one bowl, and the cookies bake fast, so you can go from craving to eating in under an hour.

Ingredients
Equipment
Method
- Melt the butter in a small pan over medium heat and cook until it turns amber and smells nutty, then pour it into a bowl and let it cool until warm.
- Add the brown sugar and white sugar to the butter and whisk until smooth and shiny.
- Mix in the egg and vanilla until the batter looks thick and glossy.
- Stir in the sourdough discard until the mixture is smooth with no streaks.
- Add the flour, baking soda, and salt, then stir gently until a soft dough forms with no dry spots.
- Fold in the chocolate chips until they are spread evenly through the dough.
- Scoop tall mounds of dough onto a parchment-lined baking sheet, leaving space between them.
- Press a few extra chocolate chips on top of each mound so they show after baking.
- Bake at 350°F (175°C) for 10–13 minutes until the edges are light golden and the centers still look soft.
- Sprinkle flaky salt on top right after baking if using, then let the cookies cool on the pan for 10 minutes before moving them.
Notes
- If the butter is too hot when mixed with sugar, the dough can turn greasy. Let it cool first.
- Too much flour will make the cookies dry, so measure carefully and stop adding once the dough is soft but not sticky.
- Overbaking will make the centers hard instead of chewy, so pull them out while they still look pale in the middle.
- Flattening the dough balls will make thin cookies instead of thick ones.
Why This Recipe Works
Browning the butter adds a deep, nutty flavor that makes the cookies taste richer. The sourdough discard adds moisture and a slight tang, which balances the sweetness. Baking the cookies while the centers are still soft keeps them thick and chewy instead of dry.
Serving Suggestions
I usually serve these cookies warm so the chocolate stays soft. They go well with cold milk or coffee. I also like stacking them on a plate and letting people grab them as they cool.
Fun Fact
Sourdough discard is safe to bake with even when it has not been fed, because the oven heat stops fermentation.
Conclusion
Store leftover cookies in a sealed container at room temperature for up to three days. You can add more chocolate chips or a pinch of flaky salt if you want extra flavor. I make these again whenever my sourdough jar starts to fill up.
