Place your dates in a blender and cover them with hot water. Allow dates to soak for 5-10 minutes. Drain and return dates to blender.
Scoop only the solid white coconut milk from the cans and add to blender. This should be about 2 ¾ cups. Then add almond milk, maple syrup, nutmeg, cinnamon, vanilla extract, and pinch of salt. Blend on high until smooth and dates are incorporated.
Add a ½ to 1 ounce bourbon, rum, or cognac to each serving glass. Pour eggnog in glasses and serve immediately. Top with a sprinkle of nutmeg. Add a cinnamon stick for garnish, if desired. For non-alcoholic drinks, omit the alcohol.
Store any leftover vegan eggnog in an airtight container for 3-4 days. Natural separation will occur, so stir to re-incorporate before serving.
