Add ice to a martini glass to chill, set aside. In a shaker, combine vodka, coffee liqueur, espresso, chocolate liqueur, and RumChata peppermint bark cream.
Shake until well combined and frothy.
Wet the top of the martini glass with a lemon or simple syrup, then dip into crushed candy canes. Pour the martini and serve.
Notes
Be sure to chill the martini or coupe glasses with a few ice cubes so that the glass gets frosty and the beverage is served as cold as possible.Use a jigger to measure out the liquids that go into the drink so that everything is well balanced.Fresh brewed espresso will yield a frothy crema at the top of the drink, whereas cold brew coffee will not, but either one works well.
