In a large food processor, combine all of the ingredients and process until a sticky dough is formed.
Scoop the dough by rounded tablespoons and use your hands to roll into smooth balls. Place the balls on a baking sheet lined with parchment paper for easy removal.
Place the tray in the freezer to set for 30 minutes.
Melt the cup of dark chocolate chips (5 minutes in a 400F oven does the trick), and remove the baking sheet from the freezer. Roll each ball in the melted dark chocolate, then return them to the parchment paper to set.
If you'd like to sprinkle some crushed pecans or coconut on top for decoration, be sure to do it while the chocolate is still melted-- it will solidify quickly on the chilled truffles!
Return the chocolate truffles to the fridge or freezer until ready to serve.
Notes
For a chocolate-filled variation, add 1/4 cup cocoa powder before processing the filling ingredients.
