In a medium sauce pan, add the milk, chocolate chips, sugar and salt. Heat on medium low heat, whisking often. Continue to whisk until the chocolate melts completely and the mixture comes to a low simmer. (Do NOT let boil, as it will burn to the bottom of the pan.) Once liquid comes to a low simmer, promptly remove from heat. Add the vanilla and stir to combine.
Ladle the hot chocolate into 3 mugs, and add 1 oz. Amaretto liquor to each glass. Stir to combine. Top with your favorite toppings. Enjoy!
