Ingredients
Method
- Stir melted butter, brown sugar, and granulated sugar in a large bowl until it looks like wet sand, about 1 minute.
- Whisk in the egg and vanilla until smooth and glossy, about 30 seconds.
- Add flour, cornstarch, baking soda, and salt to the bowl and stir until just a few streaks remain, about 30 seconds.
- Fold in the white chocolate chips until evenly distributed.
- Preheat oven to 350°F (175°C) and line two baking sheets with parchment. Scoop rounded tablespoons of dough 2 inches apart and bake 10 to 12 minutes until edges are golden and centers look slightly underdone.
- Let cookies cool on the sheet for 5 minutes, then transfer to a rack. Press extra chips on top while warm.
Notes
For a bakery look, press a few extra white chocolate chips onto each dough ball just before baking. The cookies keep in an airtight container at room temperature for up to 5 days.
