Put the pitted dates, cocoa powder and orange juice in the blender. Blend until smooth. Scrape the mixture down occasionally. You might need to add extra orange juice if it gets too dry or hard to blend.

Transfer the mixture in to a bowl and make small balls. Wet your hands occasionally when making balls as the mixture is sticky.

Put ¼ cup of cocoa powder into a bowl and roll the balls into this cocoa powder.

Line a baking sheet with parchment paper and place the truffles on it. Chill for about an hour to firm up.
