OK, someone asked for the recipe I used so here it is...

2 cups butter                                
2 cups sugar                                       
2 cups brown sugar
            
4 large eggs                                                     
2 tsp. vanilla
                                    
4 cups flour                                         
5 cups blended oatmeal*(see note below)
1 tsp. salt
2 tsp. baking powder
2 tsp. baking soda (also called bicarbonate of soda)

24 oz. chocolate chips (or more, more is good, I used more)
3 cups chopped nuts (pecans or walnuts)(yes, I used more of these, too!)

*Note about what blended oatmeal is...Measure oatmeal and blend in a blender or food
processor to a powder.

Also note - most civilized people with a well equipped kitchen will have a sturdy
mixer to cream the butter and sugar and then mix the dough and a blender for the
oatmeal. We still have a basically bachelor kitchen from Alan which I am slowly
upgrading. So I made these cookies using nothing but a food processor to cream the
butter and sugar and a bowl and big spoon to hand mix the rest.

Cream butter and both sugars. Take time to make sure it is light and fluffy.
Add eggs and vanilla and mix well.
Mix together with flour, oatmeal, salt, baking powder and soda. 
Add chocolate chips, and nuts.
Roll into balls and place two inches apart on a cookie sheet. Lightly flatten balls
with the palm of your hand.

Bake for 10 minutes at 375F. (I baked them for 9 1/2 min at 170C in a fan convection
 oven.)
Makes a LOT of large cookies - like about 100 or so. You can halve the recipe but why?
They will all be quickly eaten and everyone will be very happy and grateful. Nah,
they'll be happy and ungrateful and demand more cookies!
