Gather 8 ounces of high-quality dark chocolate, 1/2 cup of heavy cream, and 2 tablespoons of unsalted butter.
Finely chop the dark chocolate and place it in a heatproof bowl.
In a saucepan, heat the heavy cream over medium heat until it just begins to simmer.
Pour the hot cream over the chopped chocolate and let it sit for a minute to soften the chocolate.
Gently stir the mixture until the chocolate is completely melted and the ganache is smooth.
Add the butter to the ganache and stir until it's fully incorporated, creating a shiny and velvety texture.
Refrigerate the ganache for at least 2 hours or until it becomes firm enough to handle.
With a spoon or a melon baller, scoop out portions of the chilled ganache and roll them into small, round truffle balls.
Roll the truffles in cocoa powder or chopped nuts for an elegant finish.
Place the coated truffles in the refrigerator for another 30 minutes to set before serving. Enjoy your homemade dark chocolate truffles!
