Crush peppermint bark or candy cane and spread on a plate. Wet the glass rim with cream or syrup, then dip in crushed candy.
Fill shaker with ice. Pour in tequila, chocolate (or vanilla) vodka, peppermint schnapps, and cream.
Shake vigorously for 15+ seconds. Strain into rimmed glass. Drizzle with chocolate syrup if desired.
Notes
Chocolate vodka adds richness, vanilla keeps it lighter. Skip cream for a less creamy drink. Top with extra peppermint bark for fun presentation. Sweetness and strength can be tweaked by vodka type.
