Jam cookies

Preheat the oven to 180 ºC and lightly butter a few baking sheets or spray with non-stick spray.
Cream the butter and sugar together until light and fluffy. Add the eggs one by one, beating well after each addition.
Add the condensed milk, beating until well blended.
Sift the cake flour, baking powder, cream of tartar and salt together. Add to the butter mixture and mix to form a dough.
Roll into small balls and arrange on the prepared baking sheets. Using the back of a wooden spoon handle, press a hole into each cookie and fill with a little jam.
Sprinkle with coconut and bake for 12 to 15 minutes until pale brown.
