Preparation Steps
Step 1: Brown the Butter

Step 2: Mix the Wet Ingredients
- Pour the cooled brown butter into a mixing bowl.
- Add the brown sugar and granulated sugar and whisk until smooth.
- Mix in the egg, egg yolk, vanilla, and sourdough discard until creamy.

Step 3: Combine the Dry Ingredients
- In a separate bowl, whisk the flour, baking soda, baking powder, and salt.
- Gradually fold the dry mixture into the wet ingredients until a thick dough forms.
Step 4: Add the Chocolate
- Fold in the chocolate chips or chunks.
- The dough will be soft and slightly sticky, this is perfect.

Step 5: Scoop and Chill
- Scoop large cookie dough balls (about 2 tablespoons each).
- Chill the dough for at least 45–60 minutes, or overnight for even thicker cookies.
Step 6: Bake the Cookies
- Preheat the oven to 350°F (175°C).
- Place chilled dough balls on a parchment-lined baking sheet.

- If desired, sprinkle warm cookies with flaky sea salt.
- Allow the cookies to cool on the tray for 10 minutes before transferring.

FAQs
Can I use active sourdough starter instead of discard?
- Yes, but it will slightly change the texture. Active starter contains more moisture and air, so the cookies may spread a bit more. Discard is recommended for thicker cookies.
Does sourdough discard make the cookies taste sour?
- Not at all. It adds a mild tang that balances sweetness, but the brown butter and chocolate dominate the flavor. The result is rich, not sour.
Can I freeze the dough?
- Absolutely. Scoop dough balls and freeze on a tray. Once firm, transfer to a freezer bag. Bake from frozen by adding 2 extra minutes.
Why brown the butter?
- Brown butter adds nutty, caramel-like flavor and gives these cookies their signature depth. It enhances the richness of the dough and pairs beautifully with sourdough discard.
How do I keep the cookies soft?
- Store them in an airtight container with a small piece of bread or a marshmallow. They’ll stay soft for up to 5 days.
My cookies spread too much—why?
- This happens if the dough wasn’t chilled long enough or if the brown butter was still warm. Chill until the dough is firm before baking.
