Mary's Chocolate Chip Cookies

First off, you should know I do not like chocolate chip cookies! Growing up we always made what was supposedly the Mrs. Field's recipe. Everyone but me liked them. Well, my next door neighbor has brought us chocolate chip cookies a couple of time and hers are delicious! I finally asked her for the recipe. Mary sent me a picture of the recipe and it says "Neiman Marcus Cookies" as the title. They have ground oats in them - That's the big difference I noticed between the ones I usually make and the ones Mary makes. I also asked her what kind of chocolate chips she uses- maybe that's what makes a difference. I always buy the cheaper store brand chocolate chips and maybe I shouldn't. She uses Nestle semi-sweet chocolate chips or the Ghiradelli chocolate chips in the silver or gold bag. She says she usually halves the recipe. She doesn't add nuts.

2 cups butter
2 cups sugar
2 cups brown sugar (from the notes Mary had on the side of the recipe - I don't think she halves this?)
4 eggs
2 tsp vanilla
4 cups flour
1 tsp salt
2 tsp baking powder
2 tsp baking soda
5 cups old-fashioned oats, ground to flour in a food processor or blender
2 (11.5 oz) packages semi-sweet chocolate chips
8 oz milk chocolate Hershey bar crushed or 1 (11.5 oz) package milk chocolate chips (Mary says she just uses semi-sweet - not sure if she adds semi-sweet in place of these or skips it all together.)
2 cups chopped nuts, optional

Cream butter and sugars. Add eggs and vanilla and mix well. Mix in flour, salt, soda, baking powder and ground oats. Then gently stir in chocolate and nuts. Roll into balls with a cookie scoop (I don't even know what one is) and bake on a greased cookie sheet for 8 to 10 minutes at 375 degrees.

Update 4/10/2017 - I finally made these myself. We did a giant cookie for Myles to use to ask a girl to prom. I did half the entire recipe (including the brown sugar). I used 12 oz. of Semi-sweet Nestle Toll house chocolate chips and 4 oz of Kroger brand milk chocolate chips. To make the giant cookie, I pressed the dough into a quarter sheet cookie pan and baked at 350 for about 20 to 22 minutes.
