Heat-Treat the Flour:
Spread the flour evenly on a baking sheet and bake at 350°F for 10 minutes, stirring halfway through. Alternatively, microwave the flour in a microwave-safe bowl for 60 seconds, stirring every 20 seconds. The flour should reach an internal temperature of 165°F. Let it cool completely.
Cream Butter and Sugars:
In a large mixing bowl, combine softened butter, brown sugar, and white sugar. Using an electric mixer on medium speed, cream for 2-3 minutes until light and fluffy.
Add Wet Ingredients:
Add the milk and vanilla extract to the butter-sugar mixture and mix on low speed until combined.
Incorporate Dry Ingredients:
Gradually add the cooled, heat-treated flour and salt to the mixture. Mix on low speed until just combined. The dough should resemble traditional cookie dough.
Fold in Chocolate Chips:
Use a wooden spoon or spatula to fold in the chocolate chips.
Serve:
Enjoy the cookie dough straight from the bowl, or refrigerate in an airtight container for up to a week. Allow it to come to room temperature for easier scooping.
