Preheat the oven to 325 degrees. Line a cookie sheet with parchment paper.

Place the grated coconut in a shallow bowl and set aside.

Combine the flour, baking soda, salt and oats in a large mixing bowl.

In another bowl, cream together the butter and brown sugar until light and fluffy. Then beat in the egg and vanilla. Add the flour mixture and mix just until combined.

To shape cookies, roll the batter between your hands to form balls the size of a large walnut. Roll in the grated coconut to coat, then place on the cookie sheet and flatten to 2 inch circles with the palm of your hand. With your thumb, make a depression in the center of each and fill with a generous teaspoon of jam. Bake 20 to 25 minutes, until lightly browned. Transfer to racks to cool.
