Chocolate Chip Cookies

In the bowl of an electric mixer fitted with the paddle attachment or beaters, beat the butter and both sugars on medium speed (or high speed if using a hand mixer) for 3 minutes, or until light and fluffy, scraping down the sides and bottom of the bowl as necessary. Add the vanilla and eggs and beat for 2 minutes more. Scrape down the bowl. Add the salt and baking soda and beat briefly until evenly combined. Add the flour and mix on low speed until the dough is uniform. Mix in the chocolate chips.

Cover the bowl with plastic wrap or scrape the dough into an airtight container and let rest in the refrigerator until firm, a few hours or overnight. (Alternatively, if you don't want to wait, form the dough into balls on the baking sheets as instructed below, and chill in the fridge until firm, about 30 minutes.)

Preheat the oven to 350°F (175°C) and set a rack in the middle position. Line a 13 x 18-in (33 x 46-cm) baking sheet with parchment paper.

Drop the dough in firmly packed 1½-tablespoon balls onto the prepared baking sheet, spacing them about 2 inches apart. (I use a #40/1½-T cookie scoop with a wire trigger.) For thick cookies, it's important to really pack the dough in the scooper or with your hands. Bake for 11 to 13 minutes, until golden around the edges but still soft and pale in the center. Let cool for a few minutes on the baking sheet, then transfer to a wire rack to cool completely. Repeat with the remaining cookie dough, refrigerating the dough between batches. The cookies will keep in an airtight container at room temperature for up to 3 days.
