Add the egg whites, sweetener, vanilla extract, and salt to a mixer and beat on high speed until the mixture is thick and doubled in size.
Gently fold in the shredded coconut until it is coated with the egg whites.
Use a small cookie scoop and place the macaroons on a silicone or parchment paper-lined baking sheet. Bake 20-25 minutes until the coconut is toasted on the top and beginning to brown on the bottom lightly.
Allow the macaroons to cool completely.
Melt 1 tablespoon of coconut oil and 1 cup of sugar-free dark chocolate chips and stir to combine. Dip each macaroon in the chocolate and place on a silicone baking sheet or wax paper to dry. Drizzle the remaining chocolate over the macaroons.
