Preheat Oven: Preheat your oven to 350°F (175°C)—line two baking sheets with parchment paper or silicone mats.
In a large bowl, cream the softened butter with both white and brown sugar until the mixture is smooth and fluffy. Beat in the eggs, one at a time, and then add the vanilla extract.
In a separate bowl, whisk together the flour, baking soda, baking powder, and salt until everything is well combined. Gradually add the dry ingredients to the wet ingredients, mixing until just combined.
Gently fold in the chocolate chips using a wooden spoon or spatula. Make sure the chips are evenly distributed throughout the dough.
Form Cookies: Drop spoonfuls of dough onto the prepared baking sheets, leaving about 2 inches of space between each cookie to allow for spreading.
Bake the cookies in the preheated oven for 10 to 12 minutes, or until the edges are golden and the centers remain soft. Avoid overbaking for a chewy texture.
Let the cookies cool on the baking sheet for 5 minutes before transferring them to a wire rack to cool completely.
