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.
Pour the chocolate into a fondue pot or a bowl and place on a dessert board with your favorite dippers.
