I make these cookies for Christmas; individually wrapped, these BIG COOKIES make nice thank you treats for teachers, the mail man, the UPS man, etc.

The flavor of this chocolate chip cookie the best I've ever found, with tons of chocolate and walnuts.  This recipe makes about 24 HUGE 5" cookies.

1/2 cup rolled oats 
2  1/4 cups flour
1  1/2 teaspoon baking soda
1  teaspoon salt
1/4 teaspoon cinnamon
1 cup butter (room temperature)
3/4 cup brown sugar
3/4 cup regular white sugar
1 1/2 teaspoon vanilla
1/2 teaspoon lemon juice
2 eggs
3 cups semi-sweet chocolate chips
1 cup walnuts chopped

Put the rolled oats in the food processor and process until you get a fairly fine powder. In a bowl, mix the oat "powder" with the flour + baking soda + salt + cinnamon and set aside.
In a large bowl, beat the room temperature butter, sugars, vanilla and lemon juice until it is smooth and creamy. Add the eggs and mix until smooth.

Add the dry ingredients, 1 cup at a time, mixing well in between each addition. Dough is going to be very stiff, so a stand mixer works well for this.  

Add the chocolate chips and nuts and mix until well combined.  CHILL THE DOUGH FOR ABOUT 1 HOUR.

Each cookie takes a little less than 1/4 cup of cookie dough. I use my ice cream scoop to measure them out.

Roll the 1/4 cup of cookie dough in your hand and place six cookie dough balls on every large cookie sheet (at least 5" apart).  Bake in...
