In a high speed blender, add vanilla ice cream ,eggnog, and ground cinnamon.
Blend until smooth.
Serve in the individual glasses. Top with whipped cream and sprinkle with cinnamon.
Notes
Use more eggnog for a stronger flavor but also for a runnier milkshake.
Eggnog Ice Cream- for an extra flavorful experience use eggnog ice cream instead of vanilla ice cream at a 1:1 ratio.
Deluxe - top the shake with whipped cream and sprinkle with ground cinnamon for an extra special look.
Fireball Flavor - use fireball eggnog for a tasty variation.
Chocolate Ice Cream-use chocolate ice cream instead of vanilla ice cream at 1:1 ratio to add a chocolate taste.
Maraschino Cherry- Make it a special treat by adding a maraschino cherry on top for appearance.
Whipped Cream-We are big whipped creamy fans over here and adding whipped cream gives this treat an extra creamy taste.
Kid Friendly - this is a fan favorite with kids. Eggnog can sometimes have a really strong taste, but when paired with creamy vanilla ice cream, it makes this delicious holiday treat have a sweet custard taste.
