Preheat oven to 350°F and line cookie sheets with parchment paper.
Beat the softened butter until smooth.
Beat in the granulated sugar and the brown sugar until smooth.
Add eggs one at a time and blend well.
Add in vanilla, and stir to combine.
In a separate bowl, combine the all-purpose flour, salt, and baking soda.
Slowly beat the dry ingredients into the wet ingredients until incorporated.
Add the quick oats a little at a time until combined.
Use a #40 cookie scoop (or scoop by 1 ½ tablespoonsful of dough) and scoop cookie dough onto the cookie sheets, leaving 2 inches of space between each cookie.
Bake for 10-11 minutes.
Remove the cookies from the oven and allow them to cool for 10 minutes before transferring them to a wire cooling rack to cool completely.
Cool completely before icing.
Oatmeal Cookie Icing
Combine the confectioner's sugar together with the milk and vanilla extract.
Mix until the icing is smooth.
Once the cookies are completely cooled, ice the cookies by dipping the cookies face down into the bowl of icing. Use a spoon to help lift the cookies out of the icing if needed.
If the cookies are very soft even after cooling - drop 1 teaspoon worth of icing on the top of each cookie and use the back of the spoon to spread the icing around.
Allow the icing to harden completely before storing.
Notes
Use quick oats, not old-fashioned. Quick oats make a softer cookie.
Cool cookies completely before icing or the icing melts into a puddle.
Dip the cookies face down into the icing if they are firm. Drop and spread with a spoon if they are soft. The icing sets the same either way.
Make the icing while the cookies cool. It comes together in one minute.
Freeze dough balls for up to 3 months. Bake from frozen, adding a minute or two.
Store with parchment paper between layers so the icing does not stick.
