Preheat oven to 350 degrees F. Line baking sheets with parchment paper.
In a medium mixing bowl, whisk together the flour, baking soda and salt. Set aside.
In another mixing bowl, use an electric mixer to cream together the butter, brown sugar granulated sugar until light and fluffy. Add the egg and vanilla and mix until smooth. Gradually, add the flour mixture and mix until just combined. Stir in the chocolate chips.
Scoop out decent portions of the dough and roll them into balls. The recipe makes 6 jumbo cookies, so divide the dough into 6 equal portions. Place the balls of dough on the prepared baking sheets, leaving lots of room between the cookies to allow for spreading while baking.
Bake for 18 to 20 minutes, or until they are golden brown along the edges.
Remove the baking sheets from the oven and before the cookies cool down, push some more chocolate chips on top of each cookie.
Let the cookies cool down completely and then remove them from the baking sheets.
Notes
If the dough is too soft, cover and chill for a while so it's easier to handle.
Leftovers can be stored in a cookie jar at room temperature or the fridge for up to 3 day.
