Preheat the oven to 350 degrees F.
Cream together the sugars and softened butter by hand or using a mixer.
Add eggs 1 at a time and the vanilla, beat well in between.
In a sperate bowl mix the flour, salt, baking soda and baking powder.
Add the dry to the wet in a few additions, mixing well.
Add the oats and chocolate chips and mix well to incorporate.
Scoop out 1 inch diameter balls or make them and roll them.
Place on a silicone matt or parchment paper lined cookie sheet, spread out well.
Bake between 12-15 minutes (12 minutes in my convection oven) until browned slightly. They might look slightly underdone still, but that is ok if you want them chewy!
Slide the parchment or silicone onto a cooling rack. Wait until completely cool to remove or they will fall apart.
Cool completely on a rack before stacking or storing. Enjoy the chewy goodness!
