In a large bowl combine coconut, icing sugar, coconut essence and condensed milk. Stir with a spatula until well combined.
Roll a tablespoon full of mixture (25g) into balls and place on a tray lined with baking paper. Place in fridge to firm up whilst melting the chocolate.
In a small microwave safe bowl, melt the chocolate chips with coconut oil in 30 second bursts, stirring in between until fully melted and smooth.
Using 2 forks, dip each ball into the chocolate allowing the excess chocolate to drip off. Place them back onto the tray lined with baking paper and let stand until set, approx. 15 minutes. Store in fridge until chilled. Drizzle remaining chocolate on top for decoration.
