Combine your pecans, almonds, and cocoa powder in your food processor and pulse until you have a crumble consistency, not powder
Add your dates and pulse until the a mixture is formed, it should resemble a paste (you made need to keep scraping the sides down to help your trusty food processor)
If your mixture is too thick, you can add 1 to 2 tablespoons of water to help you form the truffles (don't add too much or you will get mush)
Transfer your mixture to a mixing bowl and add your cinnamon and vanilla bean seeds and mix well by hand
Form your mixture into 10 equal size truffles
Roll your truffles into the shredded coconut, cocoa powder, both or any other garnish you want. You can used crushed macadamia nuts, sesame seeds, etc
Store in your refrigerator covered for up to 2 weeks
