Line 1 small and 1 large cookie sheet with parchment paper or a silicone baking mat. Set aside.
In a large mixing bowl, beat the butter and salt on low and increase to medium speed until combined.
Add the sugars and continue beating until combined.
Add the egg, egg yolks and vanilla extract and beat until combined, then briefly set aside.
In a medium sized bowl, whisk together the flours and baking soda until well combined.
Gradually add the dry mixture to the wet mixture until combined.
Mix in the chocolate chips until well combined, but not overly worked.
Use the Ice Cream Scooper to portion out the 17-18 cookies onto the small cookie sheet and pop into the freezer for an hour. Ideally, shape each cookie dough into a tower.
Preheat oven to 350°F / 176° C.
After an hour, place 6 frozen cookie dough "towers" onto a large lined cookie sheet and pop into the oven for 15-17 minutes. Rotate the cookie sheet halfway to ensure even baking.
Take the cookies out once the sides are golden and the middle is just turning golden brown.
