Add the chocolate and cream to a saucepan over very low heat. Use a rubber spatula to stir the mixture until the chocolate is melted and the cream is just incorporated. Turn off the heat and set aside to cool.
Transfer the melted chocolate ganache to a shallow pan with sides, like an 8 x 8 baking dish. Cover with plastic wrap or foil, and refrigerate for 30 minutes or until the chocolate mixture is cooled and just firm enough to scoop out with a spoon & form into balls.
Prep your truffle station by lining a baking sheet or plate with parchment paper, and spreading out each topping you are using on a small plate.
Use a cookie dough scoop or tablespoon measuring spoon to scoop 1 Tbsp of chocolate at a time into your hands. Gently roll into a ball shape with your hands, then roll in toppings of your choice, pressing lightly so they stick. Lay out on the parchment lined plate, then transfer to the refrigerator.
Eat after about 10 minutes of "setting" in the fridge, or whenever you're ready!
Store in the refrigerator, and enjoy! They taste great right out of the fridge, but I like them most after sitting out at room temperature for a few minutes to soften a bit.
