Preheat your oven: Begin by preheating your oven to 350 degrees F. While it's heating up, line two baking sheets with parchment paper and set them aside.
Mix the butter and sugars: In your mixing bowl, place the softened butter and both sugars. Use a stand mixer with the paddle attachment or a hand mixer to cream the ingredients at low speed until the mixture becomes light and fluffy.
Add the egg and vanilla: Incorporate the egg and vanilla extract into the mixture, blending at low speed until well combined.
Prepare the dry ingredients: In a separate bowl, whisk together the flour, baking soda, and salt. Gradually add the dry ingredients to the butter mixture and mix until just combined.
Fold in the chocolate chips: Finally, stir in the milk chocolate chips until they are evenly distributed throughout the cookie dough.
Portion the dough: Use your trusty cookie scoop to drop rounded tablespoons of cookie dough onto an ungreased baking sheet, ensuring there's some space between each cookie.
Bake to perfection: Slide the baking sheets into the preheated oven and let the cookies bake for about 10-12 minutes, or until the edges turn golden but the centers remain delightfully soft.
Cool and indulge: Allow the cookies to cool for 5 minutes on the baking sheet before transferring them to a wire rack to cool completely. This will be the hardest part, as the aroma will tempt you to grab one right away.
