In a large bowl combine the oats, flours, baking soda and salt. Stir to combine and set off to the side.
In the bowl of your mixer, add the butter, sugars and peanut butter. Mix on medium speed until fluffy {about 3-5 minutes}.

Reduce the speed to low and gradually add in the flour/oat mixture until combined.
Lastly add in the cup of chocolate chips and mix until combined.
