Ingredients
Method
- Whisk melted butter, brown sugar, granulated sugar, and salt in a large bowl for 1 minute until smooth.
- Add egg, vanilla, and sourdough discard and whisk 30 seconds until thick and uniform.
- Fold in flour and baking soda with a spatula until just combined, about 15 strokes.
- Fold in chocolate chips, cover, and chill dough at least 30 minutes. Preheat oven to 350°F (175°C).
- Scoop 2-tablespoon portions onto parchment-lined sheets. Bake one sheet at a time for 10–12 minutes until edges are golden and centers look slightly underdone. Cool on the sheet 5 minutes, then transfer to a rack.
Notes
Chill time of 30 minutes to overnight is not included in prep or cook time. The dough can be chilled up to 36 hours for deeper flavor. For consistent sizing, use a #40 cookie scoop.
