Can I use sourdough discard straight from the refrigerator?

Yes. Cold sourdough discard works well, but allowing it to come to room temperature first makes it easier to mix evenly into the dough. This helps create a smoother batter and ensures the ingredients combine more consistently.

How long can I store Brown Butter Sourdough Discard Chocolate Chip Cookies?

Store the baked cookies in an airtight container at room temperature for up to 5 days. For longer storage, freeze the cookies for up to 2 months or freeze the unbaked cookie dough for up to 3 months. Bake frozen dough balls directly from the freezer, adding an extra minute or two to the baking time.

Why is browning the butter important for this recipe?

Browning the butter gives these Brown Butter Sourdough Discard Chocolate Chip Cookies their signature rich, nutty flavor. As the milk solids caramelize, they develop deep toffee-like notes that pair beautifully with chocolate and the slight tang of sourdough discard, making the cookies taste more complex than traditional chocolate chip cookies.

Instructions

Brown the butter over medium heat until golden brown and fragrant. Transfer it to a mixing bowl and let it cool for 10–15 minutes.
Whisk the brown sugar and granulated sugar into the browned butter until smooth.
Add the egg, egg yolk, vanilla extract, and sourdough discard. Mix until fully combined.
In a separate bowl, whisk together the flour, baking soda, baking powder, salt, and cinnamon.
Gradually fold the dry ingredients into the wet ingredients until just combined.
Fold in the chocolate chips or chopped chocolate.
Cover and chill the dough for at least 2 hours or up to 72 hours.
Preheat the oven to 350°F (175°C) and line baking sheets with parchment paper.
Scoop about 2 tablespoons of dough per cookie and place them 2 inches apart on the prepared baking sheet.
Bake for 10–12 minutes, until the edges are golden and the centers are still slightly soft.
Add extra chocolate chips to the tops if desired and sprinkle with flaky sea salt.
Cool on the baking sheet for 5 minutes before transferring to a wire rack to cool completely.

Notes

Do not overbrown the butter, as it can burn quickly.
Chilling the dough improves flavor and prevents excessive spreading.
Use room-temperature sourdough discard for easier mixing.
Underbake slightly for soft, chewy centers.
Store cookies in an airtight container for up to 5 days.
Freeze baked cookies for up to 2 months or freeze portioned cookie dough for up to 3 months.
Warm leftover cookies for a few seconds in the microwave for a freshly baked texture.
