Add black beans, honey, coconut oil and cacao to a high speed blender and whizz until a smooth paste is formed.
Transfer black bean paste to a bowl and mix in rolled oats, and coconut until very well combined.
Roll into balls. They may crumble a bit so give them a squeeze and gently roll between your hands.
Keep refrigerated for up to 3 weeks (they never last more than a day in our house!). I've also made large batches and frozen them. They freeze well.
