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

In a medium saucepan, melt the butter over low heat. Once melted, remove from heat and let it cool slightly.

In a large mixing bowl, combine the melted butter, light brown sugar, and granulated sugar, whisking until smooth.

Add the eggs one at a time, mixing well after each addition. Stir in the vanilla extract.

In another bowl, whisk together the flour, baking powder, baking soda, and kosher salt.

Gradually add the dry ingredients to the wet mixture, mixing until just combined. Be careful not to overmix.

Fold in the chocolate chunks, ensuring they are evenly distributed throughout the dough.

Use a cookie scoop or spoon to drop rounded tablespoons of dough onto the prepared baking sheet, leaving space between each cookie.

Bake for 10-12 minutes or until the edges are lightly golden. The centers will appear soft, but they will firm up as they cool.

Allow the cookies to cool on the baking sheet for a few minutes before transferring them to a wire rack.
