With a mixer beat butter until light and creamy. Add in sugars and cream together with butter. Add in beaten eggs and vanilla and mix until well combined.
In a separate bowl, combine oat flour, baking soda, corn starch and salt. Mix oat flour mixture with butter mixture and stir until combined. Add in whole oats and any mix ins, stir until combined, but do not over mix. Cover and refrigerate for approximately 24 hours.
When ready to bake, preheat oven to 350 degrees.
Scoop dough onto cookie sheets covered with parchment paper. About 1 1/2 tablespoons of cookie dough per cookie.
Bake for approximately 10-12 minutes or until lightly brown. Bake longer if you like a crunchy cookie. Remove from oven and allow to cool on cookie sheet for about 10 minutes. Store in an airtight container.
*To make gluten free: make sure to use oats that are specifically gluten free, as well as gluten free baking soda, corn starch and any mix ins.
*To make dairy free: Use a non-dairy butter substitute (I like Earth Balance Baking Sticks) or shortening. Use a non-dairy chocolate chip (I like Enjoy Life).
*When avoiding anything is your baking for health purposes, always make sure that YOU verify that YOUR ingredients are safe and meet your particular dietary requirements. Also, if you are baking for someone else with food allergies, sensitivities or special diets, make sure to consult with them (or their parent) regarding ingredients to verify if everything is "safe". Food allergies are not to be messed with, and it is always better to check and double check versus assume. To state the obvious, I am not a doctor, and this is not medical advice. :)
