1. Pour nuts into a blender or food processor, and pulse until nuts are mostly ground, with some larger nut pieces left for texture (can blend completely for less noticeable crunch). Pour ground nuts into a bowl and set aside.
2. Next, put pitted dates into your blender/food processor, and blend until a thick paste is formed.
3. Next, either scrape the date paste into the bowl with the nuts and add cocoa, vanilla, and salt, mixing by hand OR put everything into the blender with the date paste and combine in the blender. I find that my blender won't fully incorporate everything and I end up scraping it back out and mixing by hand anyway.
4. Using a small ice cream scoop or a spoon, scoop dough into mounds and roll between your palms to shape into balls. Eat immediately or store in the fridge for at least a week, maybe longer. Ours don't last long enough for me to tell you if they'd be good after that.
