Ingredients

2 1/4 cups all-purpose flour 

1/2 teaspoon baking soda 

2 sticks (1 cup) unsalted butter, room temperature 

1/2 cup granulated sugar 

1 cup packed light brown sugar 

1 teaspoon kosher salt 

2 teaspoons pure vanilla extract 

2 large eggs 

12 ounces semisweet chocolate chips (2 cups) 

Preparation

Preheat oven to 350°F with racks in the upper and lower third positions. In a small bowl, whisk together flour and baking soda; set aside. In the bowl of a stand mixer fitted with the paddle attachment, beat butter and both sugars on medium speed until light and fluffy, about 3 minutes. Add salt, vanilla, and eggs; mix to combine. Reduce speed to low and gradually add flour mixture, mixing until just combined. Mix in chocolate chips.

Using a tablespoon measure, drop heaping portions of dough about 2 inches apart on baking sheets lined with parchment paper.

Bake until cookies are golden around the edges, but still soft in the center, 8 to 10 minutes. Remove from oven, and let cool on baking sheet 1 to 2 minutes. Transfer cookies to a wire rack and let cool completely. Store cookies in an airtight container at room temperature up to 1 week.
