01 - Gently melt the chopped dark chocolate in a heatproof bowl set over a saucepan of simmering water (double boiler method). Stir continuously until the chocolate is completely smooth. Remove from heat and allow to cool slightly for approximately 5 minutes.
02 - In a separate medium bowl, thoroughly mash the ripe avocado until it achieves a consistent, creamy texture with no lumps.
03 - Add the slightly cooled melted chocolate, pure vanilla extract, and a pinch of sea salt to the mashed avocado. Stir vigorously until all components are thoroughly integrated and the mixture possesses a glossy sheen.
04 - Cover the bowl containing the chocolate-avocado mixture and refrigerate for 1 hour, or until the mixture is firm enough to be easily scooped and shaped.
05 - Line a baking tray with parchment paper. Utilize a small scoop or spoon to divide the chilled mixture into approximately 18 equal portions. Gently roll each portion between your palms to form smooth, round truffle bites.
06 - Place the prepared coatings (unsweetened cocoa powder, chopped nuts, or shredded coconut) in separate shallow dishes. Roll each truffle bite in your desired coating until evenly covered.
07 - Arrange the finished truffles on the parchment-lined tray. Refrigerate for at least an additional 30 minutes to allow the flavors to meld and achieve the optimal texture before serving.
