Your favorite holiday drink — creamy with strong notes of cinnamon and nutmeg — is now contained in a sweet dessert offering that is perfect for your holiday dessert table (or any time during the year you find yourself with an eggnog craving).
Butter an 8-inch square pan, and set aside.
Bring the sugar, butter, and eggnog to a boil in a medium sauce pan over high heat.
Cook for 8 to 10 minutes, or until a candy thermometer registers 234 degrees F (soft ball stage). Stir to prevent scorching.
Remove the pan from the heat, stir in the white chocolate and spices. Stir until smooth. Then, add the marshmallow cream, vanilla extract, and rum. Mix well.
Pour the fudge into the prepared pan. Allow to cool, and set. Finally, cut and serve!
