In a large punch bowl, pour in the eggnog, peppermint-flavored syrup, and milk. Whisk together gently until all components are well combined and smooth.
Next, add the vanilla extract and peppermint extract into the mix. Stir gently to incorporate these fragrant flavors without losing the creamy texture.
Cover the punch bowl and place it in the refrigerator. Chill for at least 30 minutes to allow the flavors to meld together harmoniously.
After chilling, stir the punch again to ensure everything is well mixed and frothy. Using a ladle, pour the punch into individual glasses or festive cups.
Generously top each glass with whipped cream, creating a beautiful fluffy layer on the surface.
For a delightful finishing touch, sprinkle crushed peppermint candies on top of the whipped cream and add a fresh mint leaf to each glass for color and aroma.
Notes
For an extra festive look, serve the punch in a glass bowl and set it on a decorative tray with additional mint leaves and peppermint candies around the base.
