Method
Preparation
- Whisk together flour, baking soda, cornstarch, and salt in a large bowl.
- In another bowl, mix melted butter, brown sugar, and granulated sugar until smooth.
- Add the egg, egg yolk, and vanilla to the butter mixture. Mix until combined.
- Stir the wet ingredients into the dry ingredients using a spatula. The dough should be soft and shiny.
- Fold in the chocolate chips.
- Cover and chill the dough for at least 2 hours or overnight.
Baking
- Preheat the oven to 325°F (163°C). Line baking sheets with parchment or silicone mats.
- Scoop 2 heaping tablespoons of dough for each cookie and roll them into tall, rough balls.
- Place cookies about 3 inches apart on the baking sheet.
- Bake for 13–14 minutes until the edges are golden and the centers look soft.
- Let them cool on the sheet for 10 minutes before transferring to a rack.
- Optional: Press extra chocolate chips on top while warm for an indulgent touch.
Notes
Chill the dough for chewiness and flavor. Store in an airtight container at room temperature for up to a week, or refrigerate for up to two weeks. Freeze for up to three months.
