Chill cream or coconut milk beforehand for the creamiest texture. Use freshly brewed espresso syrup or cold brew concentrate to enhance coffee flavor in non-alcoholic versions. Layer cream slowly over ice for the classic marbled effect. Experiment with coffee liqueur brands and try variations like vegan, spiced, mocha, decaf, extra creamy, or frozen White Russian. Store leftover vodka and coffee liqueur mix refrigerated up to 3 days; add cream just before serving.
