Put all ingredients into a blender and blend until creamy and smooth. Put in the fridge to get cold or serve over ice.
Add brandy or rum for an alcohol treat. Top with whipped cream if desired.
Serve!
Notes
Make Sure To Blend Long Enough: If the mixture is still a little gritty, it needs to be blended for more time.
Taste And Adjust: Everyone has their own idea of how sweet or spiced eggnog should be. Start small with maple syrup and spices, then blend and taste until it’s perfect for you.
Avoid Boxed Coconut Milk: The boxed version just isn't as rich or creamy as the canned version! Trust me on this one, the canned version is the way to go.
Don’t Skip The Salt: Even a tiny pinch makes the vanilla and spices pop. It brings balance to the whole drink.
Make It Ahead: I've noticed that this eggnog gets even better after a few hours in the fridge. The flavors blend and mellow, and it thickens up slightly as it chills.
Without A High Speed Blender: If you are not using a high speed blender, you can soak the cashews overnight, boil them for 30 minutes or grind the dry cashews into a fine powder using a coffee grinder (do not soak them for this method).
