Preheat your oven to 350°F (175°C) and line baking sheets with parchment paper.

Partially melt the unsalted butter and allow it to cool slightly.

In a large bowl, cream the cooled butter with both sugars until light and fluffy. Add eggs one at a time and mix in vanilla.

In a separate bowl, whisk flour, baking soda, and salt. Gradually mix these into the wet ingredients until just combined.

Fold in chocolate chips gently until evenly distributed.

Scoop dough onto prepared baking sheets, spacing them 2-3 inches apart.

Bake for 10-12 minutes for large cookies, or 8-9 minutes for medium cookies. Look for lightly golden edges.

Cool on baking sheets for 5 minutes before transferring to a wire rack.
