Start by finely chopping the chocolate. You want it to be small thin pieces so that it will melt smoothly in the next step. Place the chopped chocolate in a bowl.
Pour heavy cream into a microwave safe measuring cup or bowl. Microwave the heavy cream for 1 minute or until it begins to boil.
Add the vanilla extract to the cream and stir together.
Pour the hot cream over the chopped chocolate in the bowl and let it sit for 2 minutes. Then stir until chocolate is completely melted and smooth.
Place the chocolate in the refrigerator for 30 - 60 minutes or until it cools enough to be a consistency that can be molded easily.
Scoop out about 1 tablespoonful of chocolate and roll into a ball.
Roll completed ball in topping of your choice.
Serve immediately or store in the refrigerator or freezer.
Notes
To make ahead, follow the instructions as written and then store in the following ways:Room Temperature - If you'll be serving these in the next 3-4 days you can store them in an air tight container at room temperature and serve immediately. If you are storing them in layers, it works best to place a sheet of wax or parchment paper between each layer to keep them from sticking together.Refrigerator - If you are making these up to 2 weeks ahead of time you can store them in an air tight container in the refrigerator. Again, make sure to separate layers with wax paper or parchment paper to keep them from sticking together.When you are ready to serve allow them to warm to room temperature for about 30 minutes before serving. Freezer - You can also store them in the freezer. Place them in an airtight container with wax or parchment paper between the layers and freezer for up to 2 months.When you are ready to serve allow them to warm to room temperature for about 60 minutes before serving. Note for best results when refrigerating or freezing:Because there tends to be a bit of condensation that appears on top of the truffles as they come to room temperature the powder coated truffles don't do as well. The powder gets a bit moist from the condensation.If you want to make the powder coated variety or sprinkle coated variety ahead of time I suggest making the truffles and refrigerating or freezing before coating them in the powder.When you are ready to serve let them come to room temp and quickly roll in powder or sprinkles before serving. This will guarantee the best results every time!
