Mix chocolate liqueur, Creme de Cacao, half-and-half, peppermint schnapps and some ice cubes in martini shaker. Shake for 20 seconds and strain into a chilled martini glass. Garnish with shaved chocolate.
Place the martini glass in the freezer for an hour so it keeps your martini chilled.
You can substitute half-and-half with heavy cream or whole milk.
If you love peppermint, increase it by ½ oz or more. Just be careful as peppermint is a very strong flavor.
