For a richer flavor, use whole milk or half-and-half when preparing your hot chocolate. Adjust the amount of peppermint schnapps to your preference. Start with 1/2 part and add more to taste. To make your own simple syrup, combine equal parts sugar and water in a saucepan. Heat over medium heat, stirring until the sugar dissolves completely. Let cool before using. Consider using a high-quality white chocolate for an even more luxurious experience
