A wonderful winter treat, great as a gift too!
Recipe makes 1.75 liters (1.85 quarts | 7 cups) of chocolate liqueur.
I used rum with the alcohol content of 40% (ABV = 80 proof), you can of course use a lighter or stronger rum, and adjust the amount to your own taste.
If you don’t have powdered chocolate, you can use good quality milk chocolate. (Stir melted chocolate into warm milk and follow the recipe.)
Because alcohol has a different density than milk the two separate in the bottle. You’ll notice that your chocolate liqueur is suddenly of two different colors if it’s been standing in the fridge for a while. Shake the bottle or simply stir the liqueur with a straw before serving.
This liqueur will keep for months, if properly stored in a cool place (I keep mine in the fridge).
