Ingredients
Method
- Preheat the oven to 350°F (175°C). Line baking sheets with parchment paper.
- Beat butter, brown sugar, and granulated sugar until light and fluffy.
- Add eggs one at a time, then mix in vanilla.
- In another bowl, whisk flour, baking soda, cornstarch, and salt.
- Add dry ingredients to the wet mixture and mix until just combined.
- Fold in chocolate chips (and nuts, if using).
- Cover and refrigerate dough for at least 30 minutes.
- Scoop large dough balls onto baking sheets (about 2–3 tablespoons each).
- Bake 12–14 minutes, until edges are set and centers are slightly soft.
- Let cookies cool on the pan for 5 minutes, then move to a rack to finish cooling.
Notes
Chilling dough creates thicker, bakery-style cookies.
For extra chocolatey tops, press a few chips onto each dough ball before baking.
If cookies spread, chill the dough longer or use slightly cooler butter.
Dough freezes well — bake straight from frozen, adding 1–2 minutes.
