A rich and cozy holiday cocktail with creamy eggnog, peanut butter whiskey, and a touch of nutmeg—my Santa’s Nightcap Cocktail is pure festive indulgence!

Santa’s Nightcap Cocktail: A Little Something Special!
Santa’s Nightcap Cocktail is the perfect way to wind down during the holidays. Eggnog wasn’t always a staple for me, but at some point I started grabbing a single carton of eggnog each season for a little festive indulgence. Last Christmas, I played around with flavors and realized how well peanut butter whiskey pairs with the creamy, spiced notes of vegan eggnog, such as OatNog. Served in a small mug, this rich little drink is just the right size to savor by the fire or after a holiday feast. Add a dollop of whipped cream and a sprinkle of nutmeg for the ultimate finishing touch!
Why You’ll Love This Recipe
- Rich and decadent. The combination of creamy vegan eggnog and peanut butter whiskey creates an indulgent holiday drink with warm, dessert-like flavor.
- Quick and simple. With just a few ingredients and less than 10 minutes to make, it’s perfect for last-minute holiday entertaining.

- Fully vegan. Using oat-based eggnog keeps the drink entirely plant-based without sacrificing the classic flavor or creamy texture.

Ingredient Highlight: Eggnog
Eggnog is the star of this holiday cocktail, bringing its creamy texture and warm, spiced flavor to every sip. While classic versions are traditionally dairy- and egg-based, today’s plant-based eggnogs capture the same festive sweetness and richness using ingredients like oats, almonds, or coconut. It’s the ultimate holiday drink—just made lighter, kinder, and perfect for vegan cocktails.
Madly Delicious Must-Know Tips and Questions
- Warm it Gently: Avoid boiling the eggnog mixture, as it can affect the flavor and texture. Heat over low to medium heat until just warm.
- Whipped Cream Shortcut: Store-bought vegan whipped cream works beautifully here, and oat- or coconut-based versions melt into the drink in the best way.
- Play with garnishes. Freshly grated nutmeg is classic, but a pinch of cinnamon or even a dusting of cocoa powder can add a fun, festive twist.
Can I use a different whiskey?
Yes! Flavored bourbons, spiced rums, or even a splash of Irish cream liqueur can work wonderfully in this cocktail.
What if I don’t like whiskey?
No problem! Swap the whiskey for spiced rum or leave it out entirely for a rich, non-alcoholic treat.
What kind of mug should I use?
Since the cocktail is under 8 ounces, a small mug feels just right. A festive holiday mug adds extra charm when serving.

Let’s Dish About Eggnog: Did You Know?
Eggnog has surprisingly luxe origins — it dates all the way back to medieval Britain, where it began as a warm milk punch enjoyed by the upper class. Because milk, eggs, and spices were expensive, it became a status drink reserved for celebrations and special gatherings. As the tradition spread to the American colonies, rum became the go-to spirit of choice, giving rise to what was called “rum nog” or “egg-and-grog.” In fact, early Americans loved eggnog so much that there was even an “Eggnog Riot” at West Point in 1826 after cadets smuggled in too much alcohol for their holiday festivities.
Around the world, variations evolved: Puerto Rico has coquito (coconut-based and naturally dairy-free), Mexico enjoys rompope, and Germany has a thicker version called eierlikör. Today, modern plant-based eggnogs have joined the family — proving that this centuries-old drink is still evolving.
