Preheat oven to 350 degrees F. In a small bowl, combine the first 3 ingredients:  flour, baking soda, and salt, and set aside.

In a medium mixing bowl, cream together the butter, and both sugars until smooth. Add the egg and vanilla and beat until light and fluffy. Slowly pour in the flour mixture, then add the coconut, stirring until combined. Drop about a teaspoonful of dough about 2 inches apart onto an ungreased baking sheets {I use silpats}.

Bake for 8 to 10 minutes or until golden. Cool before serving.
