The cookies were easy and successful. The obligatory initial sampling went well with an afternoon cup of tea. The recipe, for those interested:
Cream together 1/2 cup each of white sugar, brown sugar and butter.
Then add:

1/4 tsp salt
1/2 tsp baking powder
1 tsp vanilla
1 cup of quick (rolled) oats
3/4 cup of flour
1/2 cup of coconut (shredded or flaked)
1/2 tsp of cinnamon and a pinch of nutmeg
Mix it all up, spoon out globs and bake in a 350 oven, for about 10min or until browned.
The original recipe called for a 'can of flaked coconut' but that's apparently an obsolete delivery method. Can't say I remember ever seeing coconut come in cans. You could probably double the coconut without much of an issue - I found half a cup to work out nicely. You can taste it, but still taste the oatmeal flavour.
