2 sticks butter, softened
1 cup packed light brown sugar
1/2 cup white sugar
2 teaspoons vanilla
1 1/4 cups flour
1/2 teaspoon baking soda
1 teaspoon salt
3 cups oats
1 cup chopped walnuts
1 cup semi-sweet chocolate chips
Cream butter and sugars. Add eggs and vanilla.
Stir flour, soda, and salt together. Add to butter and egg mixture. Mix just until incorporated.
Stir in oats, nuts, and chips.
Spread evenly in a 10×15 ungreased cookie pan. The dough will be quite thick. I use a folded piece of waxed paper that I have lightly sprayed with cooking spray to spread the dough.
Bake at 375 for 20-25 minutes for gooey and chewy; 25-30 minutes for drier.
