Preheat the oven to 350 degrees. Line two cookie sheets with parchment paper.
Whisk the flour, kosher salt, and baking soda together in a medium bowl.
Beat your butter, sugar and brown sugar together with your mixer on medium speed until light and creamy, about 5 minutes.
Add in the eggs one at a time and then vanilla just until combined.
Turn the speed down to low and carefully add in the flour mixture just until it's combined.
Stir in the chopped chocolate.
With a 1/4 cup scoop, scoop out the dough into balls.
Arrange them on a sheet pan about 2 inches apart.
Bake for 15 to 18 minutes, just until the edges start turning brown. Halfway through rotate the pans so the cookies will cook evenly.
Let them cool on the cookie sheet for 5 to 10 minutes.
