I used to mourn eggnog season—because one cup of the traditional stuff could wipe out my whole daily carb budget. After a few sad attempts (one involved scrambled eggnog… don’t ask), I finally cracked a version that’s creamy, festive, and won’t spike blood sugar like a Christmas cookie binge.
This keto eggnog is thick enough to feel decadent, spiced just right, and easy to make dairy-free if you need it. Plus, it’s actually smooth—no weird grit, no clumping disasters.
Why This One Works So Well (Low-Carb Edition)
Traditional eggnog relies on tons of sugar for body and sweetness. Instead, I beat the yolks fluffy and use a powdered monk fruit-allulose blend, which dissolves cleanly and doesn’t recrystallize when chilled.
Heating the milk gently and tempering the eggs slowly locks in that velvety texture without cooking the eggs into a lumpy mess.
The bonus? Bourbon optional—but highly recommended for “festive metabolism management.”
What Packs Flavor Without the Carbs
- Egg yolks – The golden heart of this recipe. They give richness and structure.
- Powdered monk fruit-allulose blend – Dissolves like sugar but stays blood-sugar friendly. (Granular sweeteners = gritty eggnog. Ask me how I know.)
- Unsweetened almond milk – Lightens the mixture without adding carbs. (Or use coconut milk for nut-free.)
- Heavy cream – Serious creamy mouthfeel. Sub coconut cream if you’re dairy-free.
- Nutmeg + Cinnamon – Classic cozy vibes.
- Vanilla extract – Rounds everything out with sweet warmth.
- Bourbon (optional) – Adds depth, tradition… and slightly better shelf life.
Low-Carb Swaps That Actually Work
- Dairy-Free – Swap almond milk for coconut milk and heavy cream for coconut cream. (Slight coconut flavor but honestly, still festive and GOOD.)
- No Alcohol – Just skip it! It doesn’t change the thickness.
- Sweeter Eggnog – Bump up monk fruit blend to 70g (½ cup) if you like a sweeter sip.
Keto Missteps and How I Fixed Them
What Went Wrong | Why It Happens | How to Fix It |
---|---|---|
Scrambled eggnog | Poured hot milk too fast into yolks | SLOW drizzle while whisking like a maniac |
Grainy texture | Used granular sweetener | Always use powdered sweetener |
Thin eggnog | Didn’t cook long enough after tempering | Keep stirring over medium-low until it lightly coats the back of a spoon |
Step-By-Step: How to Make It
- Beat egg yolks: In a bowl, use a hand mixer to beat the yolks until light yellow. Gradually add the powdered sweetener and beat until dissolved.
- Heat milk and spices: In a saucepan, combine almond milk, heavy cream, cinnamon, and nutmeg. Heat over medium until just barely boiling. Remove from heat. Stir in vanilla.
- Temper eggs carefully: Slowly whisk hot milk into the yolks—thin stream only!—constantly whisking to prevent scrambling.
- Thicken gently: Return the mixture to the pan. Stir constantly over medium-low until it reaches 160°F (71°C) and thickens slightly.
- Optional bourbon: Stir in now if using.
- Chill: Transfer to a container. Cover and refrigerate 3–4 hours until cold and thick.
- Serve: Top with sugar-free whipped cream and a sprinkle of cinnamon.
Macro Hack: I portion this into 6 cups (roughly 1 cup each)—makes tracking net carbs simple.

Smart Moves I Always Use
- Letting the eggnog sit overnight makes it even thicker and silkier.
- If using coconut milk/cream, whisk it first to smooth out any clumps.
- Keep a candy thermometer handy—guesswork = scrambled eggs. Trust me.
Keeping It Keto-Friendly All Week
- Fridge: Store in an airtight bottle or mason jar for up to 4 days.
- Separation? Totally normal. Just shake or stir before pouring.
- Freezing: Not recommended. Texture changes (sadly) after thawing.
Real Keto Questions, Real Answers
Will this spike blood sugar?
Not if you stick with the monk fruit-allulose blend and keep your serving size reasonable. I’ve tested post-drink glucose, and mine stayed flat.
Can I use granular monk fruit sweetener?
Nope. You’ll get sandy eggnog. Go powdered or go home.
Is the bourbon necessary?
No, but it adds flavor and acts as a mild preservative. Plus, it’s festive. Your call.
