Add all the ingredients into a large bowl. Mix well with a spoon until well combined.
With clean hands, roll into 10 balls and place on a plate.
Place in the freezer for 20 minutes.
After 20 minutes, remove the energy balls from the freezer and melt the 4 squares of dark chocolate in the microwave. (do this in 30 second intervals until fully melted) Once melted, spoon over the energy balls before placing in the fridge for 5 minutes until the chocolate has set.
