That's bikkies to you antipodeans, but it's her recipe so she gets to call them what she likes.
About once a year I ask my sister for her oatmeal cookie recipe and then lose it; about 50% of the time I manage to make a batch before it disappears. This time, I'm whacking it on the cloud. They're kind of similar to Anzac bikkies (though to be honest, everyone seems to disagree about what exactly makes an Anzac Anzac, so I may be lying.)
Tuned to 7,000 feet, so tweak as necessary lowlanders.
1 cup butter (substitue 1/2 for applesauce if you want to make your doctor happy)
2 1/2 cups brown sugar
2 tsp vanilla extract
2 cups all-purpose flour (substitute 1/2 with whole wheat, but use a little extra)
1 cup whole wheat flour
2 tsp baking soda
1/2 tsp salt
1 1/2 cups raisins
1 1/2 cups chocolate chips
1 cup coconut
1 cup chopped walnuts
7 1/2 cups oats (lose the half if not at altitude.)
Preheat oven to 375F. Mix ingredients in order listed. Scoop into balls on a baking sheet. Bake until golden.
