Ingredients
2 1/2 cups (355 grams) all-purpose flour
1 teaspoon baking soda
3/4 teaspoon salt
12 tablespoons (1 1/2 sticks or 170 grams) unsalted butter, at room temperature
3/4 cup (150 grams) granulated sugar
3/4 cup (150 grams) brown sugar
2 large eggs
1 1/2 teaspoons pure vanilla extract
7 ounces (198 grams) semisweet or bittersweet chocolate, chopped into bite-size pieces, or 1 1/4 cups (226 grams) semisweet chocolate chips
Instructions
  1. Adjust an oven rack to the middle of the oven. Heat the oven to 350°F (180°C). Line three sheet pans with parchment paper.
  2. In a medium bowl, whisk together the flour, baking soda, and salt.
  3. In the bowl of a stand mixer fitted with a paddle, beat the butter on medium speed until creamy, about 1 minute. Add the granulated and brown sugars and beat on medium speed until light and fluffy, 2 to 3 minutes. Scrape down the sides of the bowl, add the eggs and vanilla, and mix until smooth. Add the flour mixture and beat on low speed until just combined. Add the chocolate and mix into the batter on low speed.
  4. Form the dough into 1 1/2-ounce (45-gram) balls (2 tablespoons) and place 8 cookies on each sheet pan.
  5. Bake one pan at a time, rotating halfway through baking. Bake for 8 minutes, until the cookies are slightly puffed in the center. Give the pan a slight tap in the oven. Bake the cookies until the edges are just turning golden brown but the center is still soft, 2 or 3 minutes more (10 to 11 minutes total).
  6. Give the pan one final tap in the oven and then transfer the pan to a wire rack to cool. Let the cookies cool completely before removing from the pan. When pulled from the oven, the cookies will look puffed and light in color, but they will slowly deflate as they cool on the pan. Store cookies in an airtight container at room temperature for up to 5 days.
