Classic Chocolate Chip Cookies. A classic soft, chewy, chocolate chip cookie recipe. This is such a popular chocolate chip cookie recipe!
Preheat oven to 385 degrees (unless you are chilling the dough before baking). In a large bowl, cream together butter, brown sugar, and sugar for 4 minutes, scraping the sides of the bowl often.
Add eggs and vanilla and beat for 1 minute longer.
Mix in flour, cornstarch, baking soda, and salt and only mix until combined to avoid over-mixing. Fold in chocolate chunks or chips*.
Roll into balls and place on a parchment paper-lined baking sheet. I suggest using light-colored baking sheets. Don't overcrowd the cookies and give plenty of room for spreading. If you would like to chill the dough before baking, roll into balls and then cover tightly and allow to chill for 24-48 hours.
Bake for 10-12 minutes. Don't overbake. Watch for the edges to start to turn a light golden color and the middle still slightly gooey. The cookies will continue to set up after you remove them from the oven.
