Preheat the oven to 350℉ and line 2 large baking sheets with parchment paper or silicone mats.
In a large bowl or stand mixer, cream together the butter, brown sugar, and white sugar until smooth.
Beat in eggs one at a time, then stir in vanilla.
Combine the flour, baking soda, and salt then stir into the creamed mixture ⅓ at a time until just blended.
Mix in the quick oats 1 cup at a time, and then mix in the chocolate chips.
Drop by heaping spoonfuls onto the baking sheets in 3 rows of 4 cookies.
Bake for about 12 minutes checking for doneness around 10 minutes for any differences in oven temperature or cookie size. The cookies are ready when the outer edges have browned.
Remove from the oven when done and place the cookies on a rack to cool.
