Preheat your oven to 375°F. Line a baking sheet with parchment paper.
In a medium bowl, whip the butter with an electric mixer until light and airy, approximately 20 seconds.
Add both sugars to the fluffy butter and beat until pale, approximately 30 seconds.
Add the egg yolk and vanilla into the mix and beat just until they're fully incorporated.
In a separate bowl, whisk together the flour, salt, baking soda, and baking powder.
Gently combine the dry ingredients with the butter mixture, beating just until combined.
Fold in the chocolate chips, ensuring they're evenly distributed.
Scoop the dough into 12 even balls and place them on the prepared baking sheet, spaced 1 inch apart.
Bake in the preheated oven for 8 to 10 minutes. Keep an eye out for the edges to just start turning golden.
After baking, let the cookies sit on the sheet for 5 minutes before transferring them to a wire rack to cool completely, approximately 30 minutes.
