Fill shaker halfway with ice. Add all spirits, liqueurs, almond milk, and vanilla. Shake hard until chilled.
Strain into a chilled glass. Top with whipped cream.
Grate fresh nutmeg on top. Add a cinnamon stick if desired.
Notes
Use cream for a richer nog, almond milk for lighter. Adjust sweetness with extra liqueur. Always use fresh nutmeg for aroma and taste. Serve immediately for best flavor.
