Blend the peanuts, in a food processor, until they are chopped into little chunks (not a fine powder).

Then add the dates, salt and cocoa and mix together a bit in the food processor, making sure the food processor is off before you mix them by hand.

Turn the food processor back on and blend the mix until the peanuts and dates are well combined.

Extract the mixture from the blender into a mixing bowl and roll into balls.
