This was last weeks and this weeks cookie, because it makes so much dough. Four logs.
However, it could be easily cut in half.
1 box brown sugar (16 oz) :: 1 lb melted butter (4 sticks) :: 2 cups sugar :: 4 eggs :: 2 tsp vanilla :: 2 cups oats :: 2 cups corn flakes :: 4 cups flour :: 2 tsp baking soda :: 2 tsp baking powder
Mix in order. Add nuts if desired. Roll into logs wrapped in wax paper. Chill for at least 2 hours before cutting. Bake at 350 for 10-14 minutes. Can store in the freezer.
