In a heavy-bottomed saucepan over low heat, warm the cream for 3-4 minutes.
Make the coffee/espresso while the cream is warming up. I used espresso, you can use instant coffee, too.
Add the chocolate and coffee to the heavy cream. Keep the heat on low and stir constantly to melt the chocolate with the heavy cream.
Continue to melt and stir until the chocolate mixture is completely smooth.
Add in the vanilla extract and mix well.
Remove from the heat.
Line a 9x13" pan or a 9x9" pan with parchment paper, letting the paper hang over the sides. Pour the chocolate mixture into the pan and place it in the refrigerator for 2-4 hours to chill completely. It should be completely firm and be scoopable with a spoon or cookie scoop.
Use a 1" cookie scoop to scoop balls of chocolate, then roll the balls smooth.
Roll the truffles in cocoa powder, finely chopped nuts, sprinkles or coconut.
Store an an airtight container in the fridge for up to 2 weeks. Freeze for up to 3 months.
