Beat butter and sugar until light and fluffy. Mix in vanilla and salt.
Stir in flour and coconut until combined.
Form dough into 2 logs, 12 x 3 x 1-inches. Wrap in plastic wrap and chill at least 2 hours.
Preheat oven to 300F. Slice logs into 1/3-1/2 inch slices. Bake on parchment lined baking sheets for 20-25 minutes until lightly golden at edges.
Let cool completely before storing airtight. Enjoy!
