Preheat your oven to 350°F (175°C) and grease a 9x13-inch baking dish.

In a large mixing bowl, cream together the softened butter, granulated sugar, and brown sugar until light and fluffy.

Add the large eggs one at a time and the vanilla extract, then mix until smooth.

In a separate bowl, whisk together the flour, baking soda, and salt. Gradually add this mixture to the wet ingredients until just combined.

Gently fold in the chocolate chips.

Spread the batter evenly into the prepared baking dish and bake for 25-30 minutes.

Let cool in the pan for 10-15 minutes, slice into squares, and serve warm or at room temperature.
