In a medium saucepan, heat 2 ¼ cups of the milk and the chocolate chips over medium-high heat.

In a small bowl, whisk together the remaining ¼ cup of milk with the cornstarch until smooth.

When the chocolate is smooth and melted, whisk in the milk + cornstarch mixture and let everything come to a low boil.

Remove pan from heat, and whisk in the alcohol. Divide the hot chocolate into two mugs, and top with whipped cream. Enjoy immediately!
