2 1/4 cups flour
1 teaspoon baking soda
1 teaspoon salt (see headnote)
16 tablespoons (2 sticks) unsalted or salted butter, at room temperature (see headnote)
3/4 cup granulated sugar
3/4 cup packed light brown sugar
1 teaspoon vanilla extract
2 large eggs
12 ounces chocolate chips of your choice: mini semi-sweet chocolate chips, regular semisweet or dark chocolate chips or semisweet chocolate chunks
Preheat the oven to 375 degrees. Line baking sheets with parchment paper or silicone liners.
Whisk together the flour, baking soda and salt in a medium bowl.
Combine the butter, sugars and vanilla extract in the bowl of a stand mixer or hand-held electric mixer: beat on low, then medium speed. Add the eggs one at a time, beating well after each addition. On low speed, gradually add the flour to the mixing bowl, beating just until incorporated. Stir in the chocolate chips by hand. Remove from the mixer stand and use a large spatula or dough scraper to make sure the chocolate is well and evenly spread throughout the dough.
Cover and refrigerate for at least 1 hour and up to 1 day.
For mini chocolate chip cookies, scoop rounded teaspoons of dough, 3/8 ounce each.
For traditional or dark chocolate chip cookies, scoop rounded tablespoons of dough, 3/4 ounce each.
For mega chocolate chunk cookies, scoop 1 1/2 ounces to 1 3/4 ounces of dough. Form into balls, then flatten into discs about 1/2 -inch thick.
Place the formed dough onto the prepared sheets, leaving enough room for the cookies to spread.
