Preheat oven to 350°F and line 4 cookie sheets with parchment paper.
In a stand mixer, cream butter and sugars together until smooth and creamy, about 4 minutes.
Beat in eggs and bourbon until all combined.
With mixer on low, add in one cup of flour, baking soda and salt.
Add remaining flour, one cup at a time.
Fold in chocolate chips.
Using a small cookie scoop, drop evenly sized cookie dough balls on parchment paper about 2 inches apart
Bake in preheated oven for 8-10 minutes. Cookies will still look wet in centre. Don't over bake or cookies will be hard.
Remove from oven and transfer to a cooling rack to cool slightly before serving.
Let pans cool before placing another batch of cookie dough on them to bake.
Store cookies in an airtight container.
