Soak cashews in water overnight (or for at least 4 hours).

Drain the water from the cashew and place them in a blender with 2 cups of fresh water. Blend until very smooth.

Add the remaining ingredients and blend until a uniform consistency is achieved. This will require some time, as the dates take a great deal of blending.

Pour eggnog into a glass container and refrigerate until cold (all the blending will likely heat the mixture up, so for best results, refrigerate before drinking).

Do crazy awesome stuff with your eggnog.
