Preheat the oven to 350 degrees F, line a baking sheet with parchment paper, and set aside.

In a medium bowl, whisk together the flour, baking soda, and salt

In a large mixing bowl, cream the butter, sugar, and brown sugar until light and fluffy, then beat in the sour cream and vanilla extract.

Stir in the flour mixture, then fold in the chocolate chips, reserving some to decorate the top of the cookies if desired. 

Drop the dough by heaping tablespoons onto the prepared baking sheet 2” inches apart and press extra chocolate chips into the top of the cookie if desired. 

Bake in preheated oven for 8-10 minutes or until slightly golden.

Allow to cool for 5 minutes before carefully transferring to a wire rack to cool completely.
