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.
