Heat oven to 375º F. Line a rimmed baking sheet with parchment paper and set aside.
Cream the butter and both sugars until light and fluffy, about 2-3 minutes. While continuing to beat on medium speed, add in the eggs and vanilla and mix until creamy.
In a separate bowl, combine the flour, salt, baking soda and dash of cinnamon (if you'd like). Gradually add into butter mixture, stirring with a wooden spoon until combined. Lastly, add in the chocolate chips and stir.
Scoop onto baking sheet, arranging 2 inches apart so they don't touch when they bake. Bake for exactly 9 minutes (at least in my oven!) and remove from oven. Let them rest for 2 minutes on the pan and then transfer to wire rack to cook completely. Repeat until all cookie dough is used up.
