Preheat the oven to 350 F and line cookie sheet parchment paper.
Beat the cold butter and both sugars in a stand mixer on medium speed with a towel over for cover- it will get messy if you don’t. Let mix until fluffy, about 5 minutes.
Add egg yolks and vanilla extract and mix on low for 30 seconds. Mix in flour, salt, and baking soda until just combined. Fold in the chocolate chips.
Using a medium cookie scoop, scoop the dough balls on a cookie sheet about 2 inches apart- both next to each other and on top of each other. There should be 6-8 balls of dough on the cookie sheet. Place extra chocolate chips on each ball of dough.
Bake for 12-14 minutes and let cool on a cookie sheet for 5-10 minutes. Transfer the cookies to a cooling rack or enjoy!
