Pour in the eggnog, vodka, and coffee liqueur or amaretto if using.
Shake for about 10-15 seconds until well chilled.
Strain into a short tumbler or rocks glass with fresh ice.
Add whipped cream on top if desired.
Sprinkle with nutmeg or cinnamon for garnish.
For a peppermint twist, rim the glass with crushed peppermint candy before pouring.
Notes
Fresh eggnog—homemade or store-bought—tastes best. Amaretto or vanilla vodka adds sweetness, while cinnamon on top gives a nice kick. Italian eggnog offers a richer flavor. Peppermint on the rim is festive, and whipped cream adds indulgence.
