Reduce speed and add eggs and vanilla extract until just combined.
Add flour mixture and mix until just combined.
Stir in coconut.
Place balls of dough about 1/4 a cup in size on a lined baking sheet and bake for 10-12 minutes. They should look a little underdone in the center. Let them sit on the baking sheet until they are cool.
