Keto Holiday Eggnog — Low-Carb, Boozy, and Full of Spirit

There’s something magical about Grandma’s eggnog. That first sip, creamy and sweet, spiked with a generous pour of rum or bourbon—it’s a tradition that warms both heart and home. But let’s be honest: her version is packed with sugar and carbs, making it tricky to enjoy on a keto lifestyle.

Fear not! We can honor the spirit (pun intended) of her eggnog while trimming the carbs. This keto-friendly version is rich, creamy, and boozy—without the sugar crash.


Why We Make These Changes

Grandma’s recipe is traditionally loaded with sugar, milk, and heavy cream, which add up to 20–30 grams of carbs per cup. Our goals:

  1. Replace sugar with keto-friendly sweeteners

    • We use Keystone Pantry Allulose. Allulose mimics sugar’s sweetness and browning ability without the carbs or insulin spike.

  2. Replace milk with lower-carb alternatives

    • Whole milk is higher in lactose (milk sugar). Instead, we use unsweetened almond milk or macadamia milk to cut carbs while keeping creaminess.

  3. Keep the creamy, rich mouthfeel

    • We retain heavy cream—it’s keto-approved and contributes luxurious texture and body.

  4. Maintain the holiday kick

    • A mix of bourbon or dark rum keeps the boozy warmth alive. Optionally, you can spike it at serving for those who want a lighter version.

  5. Enhance the holiday flavor

    • Nutmeg, cinnamon, and vanilla are non-negotiable—they give the aroma and taste that make eggnog iconic.


Ingredients (Serves 6–8)

  • 2 cups unsweetened almond milk

  • 1 cup heavy cream

  • 4 large egg yolks

  • ½ cup Keystone Pantry Allulose

  • ½ tsp ground nutmeg, plus more for garnish

  • ¼ tsp ground cinnamon

  • 1 tsp pure vanilla extract

  • ½–¾ cup bourbon or dark rum (adjust to taste)

  • Pinch of salt

Optional: whipped cream for serving (unsweetened)


Instructions

Step 1: Temper the eggs

  1. In a medium bowl, whisk the egg yolks until smooth.

  2. Slowly pour in ½ cup of the warm almond milk while whisking continuously. This prevents the eggs from scrambling when heated.

Step 2: Heat the base

  1. In a saucepan, combine the remaining almond milk, heavy cream, allulose, nutmeg, cinnamon, and salt.

  2. Heat over medium heat until just warm—do not boil. Stir frequently.

Step 3: Cook the custard

  1. Slowly add the tempered egg yolks to the saucepan, whisking constantly.

  2. Cook over medium-low heat, stirring continuously, until the mixture thickens slightly and coats the back of a spoon (170–175°F / 77–80°C).

Step 4: Add flavor and booze

  1. Remove from heat. Stir in vanilla extract and bourbon or dark rum.

  2. Taste, and adjust sweetness or spice if desired.

Step 5: Chill and serve

  1. Let the eggnog cool to room temperature, then refrigerate at least 2 hours.

  2. Serve in glasses, garnish with extra nutmeg, and optionally a dollop of unsweetened whipped cream.

FAQ

Q: Can I make this eggnog completely alcohol-free?
A: Yes! Simply omit the bourbon/rum. You can add a splash of rum extract for flavor without alcohol.

Q: Can I make this ahead of time?
A: Absolutely. Eggnog keeps in the fridge for 3–4 days. Add alcohol just before serving if you prefer.

Q: Can I use coconut milk instead of almond milk?
A: Yes, but choose full-fat canned coconut milk thinned slightly with water for the best creamy consistency.

Q: Can I sweeten it with stevia or erythritol instead of allulose?
A: You can, but allulose gives the closest taste and mouthfeel to traditional sugar, making it the top choice.

Q: How do I know when the custard is thick enough?
A: When it coats the back of a spoon and you can draw a line with your finger, it’s done. Don’t boil—it will curdle.
