01 - Preheat the oven to 350°F. Line two large baking sheets with parchment paper and set aside.
02 - In a large mixing bowl, beat the softened butter, brown sugar, and granulated sugar together using an electric mixer on medium speed until the mixture is pale, light, and fluffy, about 3 minutes.
03 - Add the eggs one at a time, beating well after each addition. Stir in the vanilla extract until fully combined.
04 - In a separate medium bowl, whisk together the flour, baking soda, baking powder, and salt until evenly distributed.
05 - Gradually add the dry ingredient mixture to the wet ingredients, mixing on low speed until just combined. Do not overmix.
06 - Using a spatula, gently fold the semi-sweet chocolate chips into the dough until evenly distributed throughout.
07 - Scoop rounded tablespoonfuls of dough and place them onto the prepared baking sheets, spacing each mound about 2 inches apart to allow for spreading.
08 - Bake for 10 to 12 minutes, rotating the sheets halfway through, until the edges are golden brown and the centers still appear slightly soft and underbaked.
09 - Allow the cookies to rest on the baking sheets for 5 minutes to set, then transfer them to a wire cooling rack to cool completely.
