Cream together 1/2 cup butter and 1/4 cup granulated sugar
and mix in 1 egg.
Sift in 1 1/2 cups all-purpose flour and 1 T baking powder
and add 1/2 cup finely shredded coconut and 1 T milk.
Mix it all up to look like this. Yes, it's insanely dry.
Roll it into donut hole-sized balls like this (one batch should make about 16):
Roll each ball in more coconut and poke the middle of it with your little finger:
Fill the holes with jam (traditionally apricot, but also good with raspberry or strawberry), and bake at 350 for 12-15 minutes.
