My grandmother's recipie oatmeal chocolatechip cookies they are VERY heavy on the oatmeal and a very hearty cookie:
two cups vegetable shortening
four eggs
one marshmallow fluff jar filled to the line, (not the brim) with 1/2 white and 1/2 dark brown sugar
Marshmallow fluff jar filled to the line with flour
Marshmallow fluff jar filled to the line with oats (not quick cooking)
2 teaspoons baking soda
2 teaspoons salt
some vanilla
whatever is left of the chocolate chips after you are done snacking on them while you have been mixing the ingredients)
Maybe some coconut if you want (I use a lot of coconut, up to two bags)
a few dried cranberries, or raisins or nuts if you want
cream the sugar and shortening together, add eggs, mix
Sift in flour, soda and salt
mix in oats and tidbits and whatever else you want in your cookies. Mix with your hands.
Drop by teaspoon full onto waxpaper lined cookie sheets. 350 degrees for harder cookies
400 for soft cookies.
Cook until they are done. Makes mountains of cookies
If you don't have a marshmallow fluff jar, then I'm sorry, I don't know exactly how much flour, oats and sugar you need. I think maybe four cups of each?
