Equipment
Method
- Preheat the oven to 350°F.
- Line two large baking sheets with parchment paper.
- Melt the butter in a medium saucepan over medium heat, swirling often, for 5–8 minutes, until the milk solids turn amber and smell nutty.
- Pour the browned butter into a large bowl.
- Cool the browned butter for 15–20 minutes, until warm but not hot.
- Whisk the brown sugar and granulated sugar into the butter until combined.
- Whisk in the egg and egg yolk.
- Whisk in the sourdough discard and vanilla until smooth.
- In a medium bowl, whisk together the flour, baking soda, and salt.
- Fold the flour mixture into the butter mixture just until no dry streaks remain.
- Fold in the chocolate chips until evenly distributed.
- Scoop the dough into 24 portions of about 2 tablespoons each.
- Arrange 12 portions at least 2 inches apart on each prepared baking sheet.
- Refrigerate the portioned dough on the baking sheets for at least 1 hour, until firm.
- Bake one sheet at a time for 10–12 minutes, until the edges are golden and the centers look just set.
- Cool the cookies on the baking sheets for 5 minutes.
- Transfer the cookies to a wire rack to cool.
Notes
For the nuttiest flavor, watch the butter closely as the milk solids turn amber. Store cookies in an airtight container at room temperature for up to 4 days; freeze baked cookies for up to 3 months. For a dairy-free variation, use dairy-free butter and chocolate chips.
