Place 1 pint vanilla ice cream in a blender. Add 1 cup egg nog. Blend. Add more egg nog if you want a looser consistency.
Add ½ teaspoon of vanilla extract to bump up the vanilla flavor. Pour into 2 large glasses and serve.
Notes
Garnishing the Rims of the Glasses
Place some tiny or crushed candies or other little sweet things in small bowls (but bowls big enough for the glasses to be dipped in upside down). You can use mini chocolate chips(try to find the super mini chips if you can, available at baking shops and places where baking supplies are sold), crushed peppermint bark or candy canes (these may well be hanging around your home at this time of year as well) or m ‘n m’s.
