Fill a medium-large pan with 3 inches of water. Place a bowl (metal or glass. I use metal as it's lighter and easier to lift when needed) on top of the pot with water. This is what we call the double broiler method. If you have a double broiler pot, more power to you! But the bowl method works perfect.
Pour the cream into the bowl and let warm. This will take a solid 5 minutes. Whisk occasionally.
Once cream is warm, add the chocolate pieces and begin whisking.
When chocolate begins to melt, add the brandy and vanilla. Whisk and let combine. We want it warm!
Pour your chocolate fondue into the top bowl of a fondue pot. If you don't have one, it's okay. You can totally pour it into a saucepan and heat it up, while whisking, if it starts to cool down. You can also buy a small fondue pot on amazon for like $25 and up. So they're very affordable!
