Prepare the Truffle Mixture Place finely chopped chocolate in a heatproof bowl. In a small saucepan, heat cream and butter over medium heat until just simmering. Pour the hot cream mixture over the chocolate. Let sit for 2 minutes, then stir until silky smooth. Stir in vanilla extract. Cover bowl with plastic wrap and refrigerate for about 1 hour, or until the mixture is firm enough to shape.

Shape the Truffle Balls Once chilled, use a small spoon or melon baller to scoop portions of the truffle mixture. Roll between your palms to form smooth balls (about 1 inch in diameter). Work quickly, as the chocolate can soften with the warmth of your hands.

Create the “Spider Nest” Look Spread shredded coconut in a shallow dish. Roll each truffle ball in the coconut until fully coated. For variety, roll some in cocoa powder first, then in coconut for a darker “nest” look. Place finished truffles on a parchment-lined tray.

Decorate (Optional) Add tiny candy spiders, edible eyes, or sprinkle chocolate sprinkles on top for a creepy-crawly effect. Chill truffles until ready to serve.
