Begin by preheating your oven to 375°F (190°C). Line your baking sheets with parchment paper or silicone mats to ensure your cookies don’t stick and bake evenly.
In a medium bowl, whisk together the all-purpose flour, baking soda, and salt until well combined. This step ensures even distribution of the leavening agent and salt throughout the flour.
In a large mixing bowl, use an electric mixer or a sturdy whisk to cream the softened unsalted butter with granulated sugar and brown sugar. Beat on medium speed until the mixture is light and fluffy, about 3-4 minutes. This aeration is what gives the cookies a tender crumb.
Beat in the eggs one at a time, ensuring each is fully incorporated before adding the next. Then stir in the vanilla extract. This adds moisture and binds the ingredients together while enhancing flavor.
Gradually add the flour mixture to the wet ingredients, mixing on low speed until just combined. Avoid overmixing to keep your cookies tender and soft.
Stir in the semisweet chocolate chips with a spatula, distributing them evenly throughout the dough. This is where the magic begins – pockets of melty chocolate in every bite.
Use a spoon or cookie scoop to drop rounded tablespoons of dough onto the prepared baking sheets, spacing them about 2 inches apart to allow for spreading. Bake for 9-11 minutes, or until the edges are golden but the centers still look slightly underbaked. This ensures a chewy center once cooled.
Let the cookies rest on the baking sheet for 5 minutes before transferring them to a cooling rack. This allows them to set perfectly. Enjoy warm or store for later!
