In a saucepan over low heat, warm up 2 cups of milk or heavy cream until it simmers slightly. Patience is key here.
Gradually add 4 oz of bittersweet chocolate to the warm milk, stirring consistently until it completely dissolves. Keep the heat low to avoid burning.
Introduce 2 tbsp. of sugar to the mix, ensuring it dissolves and enhances the sweetness.
Add 1 tsp. of peppermint extract for that delightful holiday flavor. Adjust to your preference.
Once the chocolate has melted and the mixture has slightly thickened, turn off the heat.
Pour this luxurious chocolate blend into your favorite mugs or jars, leaving a bit of space at the top.
Now, the optional garnish: Top it off with a generous swirl of whipped cream. For extra indulgence, add marshmallows and crush candy canes for a festive touch.
