Crush candy canes and place on a shallow plate.
Lightly wet the rims of the shot glasses and dip them into the crushed candy to coat.
In a cocktail shaker with ice, pour in peppermint schnapps, white chocolate liqueur, and vodka.
Shake it like you’re trying to win a dance-off—about 15 seconds.
Strain into prepared shot glasses.
Top with whipped cream if you’re feeling fancy, and serve immediately.
