Over medium high heat, in a double boiler (or a metal or glass bowl placed over a saucepan filled 1/4 of the way with water), combine the chocolate, 2 cups of the heavy cream, brown sugar, and brandy.
When the cream begins to to steam, and the chocolate starts to melt, whisk gently to combine to form a smooth, shiny mixture. Remove from heat and place in the refrigerator. Whisk periodically until the mixture stiffens to solid mass.
While the ganache is firming up, make your whipped cream by combining the remaining whipping cream and the 1/4 cup sugar in a mixing bowl. Whip on high until the cream stands up in stiff peaks when the beaters are pulled from it. Place in the refrigerator for later use.
Once your ganache is firm, scoop out balls about 1" in diameter with a portion scoop or a tbsp. Place them on a parchment lined sheet pan and place in the fridge again to harden.
Once your truffles have hardened, place them into a quart-sized mason jar for storage.
To make your Hot Truffles Chocolate:
Pour the whole milk in saucepan. Scrape the seeds out of the vanilla bean and stir into the milk adding the vanilla bean pod as well. Heat over medium heat, or until small bubbles form on the outer edge of the milk. When the milk begins to steam, remove it from the heat.
Place two (or three, depending on how rich you want your cocoa to be) truffles into a heat safe mug. Strain the milk into a larger kettle or pour a cup of milk directly into the mug. Allow it sit for 10 seconds to begin melting the truffles before stirring.
Garnish with a spoonful of whipped cream, more to thin out the rich chocolate taste. Enjoy!
