Preheat your oven to 325°F (163°C) and line a baking sheet with parchment paper.
In a mixing bowl, whip the egg whites until they form stiff peaks.
In a separate bowl, combine melted coconut butter, powdered sweetener, and vanilla extract. Mix well and fold in desiccated coconut.
Gently fold the whipped egg whites into the coconut mixture until just combined.
Using a spoon or cookie scoop, portion out the mixture onto the prepared baking sheet, spacing them about an inch apart.
Bake for 15-20 minutes or until golden brown. Watch closely to avoid burning.
Allow to cool on the baking sheet for a few minutes, then transfer to a wire rack. Drizzle with melted chocolate if desired.
