Mrs. Fields' Cookies

I got this recipe from Aunt Linda.  I have no idea if it's an authentic "Mrs. Fields" recipe or not! Sometimes I substitute half of the the butter with coconut oil.  And sometimes I substitute some of the white flour with wheat.  Maybe to assuage the guilt?  Anyway, the secret to making these soft and delicious is to take them out of the oven when they still look undercooked.

Preheat oven to 350 degrees (325 convection)
Blend:
1 C butter
1 C sugar
1 C brown sugar
Add:
2 eggs
1 tsp. vanilla
Mix in:
2 C flour
2.5 C oatmeal (blended)
1/2 tsp. salt
1 tsp. baking powder
1 tsp. baking soda
12 oz. chocolate chips
1.5 C chopped walnuts

Scoop onto greased cookie sheet (or better yet, use a silicone mat on a jelly roll pan).  Bake for 8-10 minutes. (start with the minimum!)  Take cookies out while still a little doughy.  They will continue to cook while they cool.  Loosen from pan after 2 minutes.
