Cream + spices. Combine almond milk (2 cups), heavy cream (2 cups), whole cloves (3), ground cinnamon (1/2 teaspoon), and ground nutmeg (1/4 teaspoon) in a small saucepan. Bring mixture to a boil, then remove from heat and set aside.
Eggs. In a large bowl, combine the egg yolks (6) and sugar (3/4 cups) using an electric mixer until fluffy and the sweetener has dissolved. With the mixer on, slowly add very little at a time of the milk/cream combo to the egg yolks.
Warm. Once combined, pour contents of the bowl into the saucepan and bring to a simmer for about 3 minutes, stirring constantly. Don't allow this to boil.
Chill. Remove cloves (I do this with a spoon) and place eggnog in the fridge to cool for at least an hour.
Final touches. Add the vanilla extract (1 1/2 teaspoons) and light rum (1 1/4 cups). Top with cinnamon and nutmeg and enjoy!
