Place the dark chocolate (broken into pieces), unsalted butter, and sweetened condensed milk into a saucepan.

Heat the mixture over medium-low, stirring continuously with a heatproof utensil, until fully melted and beginning to thicken.

Continue cooking, scraping the bottom of the pan constantly to prevent burning. Cook until you can run a spatula through the middle and the mixture takes about 2 seconds to fill back in, approximately 10 minutes.

Remove the saucepan from heat. Transfer the mixture to a bowl, cover with plastic wrap, and allow to cool to room temperature. Once cooled, refrigerate until thoroughly chilled.

Scoop out spoonfuls of chilled mixture, about the size of a walnut. Roll each portion between your hands to form smooth balls.

Roll each ball in vermicelli or other toppings as desired. Place finished truffles into paper liners and serve.
