Place avocado in a food processor and blend until smooth. Meanwhile, add chocolate chips to a microwave safe bowl and melt for 1 1/2 - 2 minutes, stirring every 30 seconds. Once chocolate is melted and smooth, stir in avocado and vanilla. Cover with plastic wrap and chill until firm, at least a few hours. (I forgot to add the vanilla in mine, but they were still good! Do what you'd prefer.)

Line a cookie sheet with waxed paper. Place sprinkles in a dish for rolling. You can also use cocoa powder, powdered sugar, or sweetened coconut, if you prefer. Use whatever you would cover regular truffles in! Use a 1 tablespoon cookie scoop to scoop balls of the chocolate mixture. Roll into even sized balls. Roll in topping, place back on cookie sheet. Chill until ready to serve.
