In a coffee grinder or mini food processor, grind your shredded coconut into a flour.
Pour the shredded coconut into a mixing bowl and add the corn starch. Mix well.
Add the essential oils (if using) and quickly mix it into the dry ingredients.
Lastly, scoop in the creamed coconut and blend once more. You should have a nice, moist, powder-like consistency.
Store in an air tight container in the fridge.
Add to the bath as you are pouring the bath so that the coconut milk bath powder mixes well. The water should be almost opaque (and silky smooth on your gorgeous skin). Enjoy!
