Add all ingredients, excluding Piper-Heidsieck, to a cocktail shaker and shake over ice until well-chilled.
Strain into a chilled flute glass. Top with Piper-Heidsieck Brut Champagne.
Garnish with an orange twist.
Gingerbread Syrup
In a small saucepan over medium heat, combine all ingredients listed. Bring to a boil, stirring to make sure the ingredients blend together.
Reduce to medium low and let simmer for about 20 minutes. Once reduced and slightly syrupy, remove from heat and let sit for 10-15 minutes.
Carefully strain the whole ingredients out of the syrup. Once cool enough to handle, store the gingerbread syrup in a swing top bottle or mason jar and keep in the fridge. Syrup will keep for at least a month.
