Blend the first section of ingredients together in order until totally smooth. Pour the mixture into ice cube trays (I used 3) and freeze until hard.When you are ready to make your eggnog, get the ice cube trays out and let them soften up for 10 minutes. Blend in a high-powered blender with the second section of ingredients for about a minute until smooth (mixture will be thick). Taste and adjust sweetness, rum flavor, and nutmeg as desired. You can also add more cream and/or almond milk for a thinner beverage if you like. Serve (yields about two quarts).Store any leftovers back by the vent in your fridge where it's cold and drink the next day.
