In a saucepan, heat the heavy cream over medium heat to a gentle simmer. Remove from heat and add the brandy, vanilla, butter and chopped chocolate. Swirl the cream so that the chocolate is covered. Allow to sit for 2 minutes.
Gently whisk until completely smooth, serve immediately.
For a party, set out a large variety of treats to dip into the chocolate. I used 3-inch cocktail skewers to do the dipping. At the last minute, divide 4- or 6-ounce ramekins with the warm ganache.
If it is just a party of two, then set up a smaller selection of dip-able treats with one larger pot of chocolate in the middle.
