Add the almonds and walnuts to a food processor and pulse until roughly chopped.
Add the dates, oats, cocoa, hemp seeds, coconut, nut butter and salt.
Blitz until the mixture starts clumping together. Add a splash of water if it seems too dry.
Scoop out roughly tablespoon-sized portions and roll between your palms.
Roll in additional coconut, cocoa or chopped nuts if you fancy.
Refrigerate for around 30 minutes before eating.
