Substitute for Oats?

Is the 1 cup of oats the only thing that is used or is there flour in the recipe as well? 

Is there a reason you want to eliminate the oats?  They do make the cookie chewier than a regular chocolate chip cookie.  If it is the texture that you want to eliminate you can grind the 1 cup of oats to a flour and add that as an oat flour. You will get the taste but not the "oatiness" that oatmeal would give. 

If you want to eliminate the oats completely just add 1 cup of flour in place of the 1 cup of oats. (I have ground oats and 1 cup of oats does grind down to 1 cup of oat flour)

For your update...just add an extra cup of flour. no one will know the difference. 

Oatmeal Substitutes

You can replace oatmeal in an oatmeal cookie recipe with the same amount of ground flaxseed, rice bran, quinoa flakes or chia seeds. Ground flax has very little flavor and is likely to produce cookies that taste similar to the recipe with oatmeal, with a slightly more sandy texture

Oats and Flour do not ''translate''

and it depends on the amount of 'wet' ingredients too (eggs for example).

On the back of the Nestle Chocolate Chip bag is a recipe for Toll House Cookies. Use that recipe.

Go on any recipe site and look for a chocolate chip cookie recipe.  I like the Toll House chip recipe.

Find a recipe that does NOT use oats. The internet abounds with them.

Substitutions and altering recipes may not work out, and that is a waste of your ingredients, time and money. Find a recipe that has the ingredients you have and/or want to use.
