This luxurious keto eggnog captures everything you love about traditional holiday beverages—think velvety creaminess, warming nutmeg and cinnamon, and that perfectly sweetened finish. By swapping sugar for erythritol and using almond milk, you'll enjoy all the festive flavors with only 3g net carbs per serving.
The technique remains classic: gently warm your dairy base, temper the eggs for that silky consistency, then infuse with aromatic spices. Whether you prefer it straight-up or spiked with dark rum, this batch yields four generous glasses of cheer.
For extra frothiness, give the chilled mixture a quick spin in the blender before serving. Top with freshly whipped cream and a generous dusting of nutmeg for that picture-perfect holiday presentation.
The snow was falling sideways last December when my keto mentor Sarah showed up at my door with a mason jar of something creamy and spiced. I'd been complaining about missing holiday traditions, and she just smiled and said 'taste this' before I could even finish my sentence about how much I missed real eggnog.
I served this at our neighborhood cookie exchange and watched three different people go back for seconds, completely shocked when I mentioned there was zero sugar involved. My friend Tom actually said 'this tastes like the holidays in a cup' which is basically the highest compliment you can give a December beverage.
Ingredients
- Unsweetened almond milk: This creates the base without adding carbs, and I've found that the really creamy brands work best here
- Heavy cream: Essential for that luxurious mouthfeel that makes eggnog feel indulgent and special
- Large eggs: Room temperature eggs incorporate much more smoothly into the warm milk mixture
- Powdered erythritol: Dissolves beautifully and doesn't leave that cooling effect some sweeteners have
- Ground nutmeg and cinnamon: Freshly grated nutmeg makes a huge difference if you have it
- Vanilla extract: Pure extract really shines in simple recipes like this one
- Dark rum or bourbon: Totally optional but a splash transforms this into a proper party drink
Instructions
- Warm the milk mixture:
- Combine the almond milk and heavy cream in a medium saucepan over medium heat, stirring occasionally until steaming but never boiling
- Prepare the eggs:
- Whisk the eggs and powdered erythritol in a mixing bowl until the mixture turns pale yellow and smooth
- Temper the eggs:
- Ladle about half a cup of the warm milk into the eggs very slowly while whisking constantly, then repeat with another ladleful
- Cook the custard:
- Pour everything back into the saucepan and cook over low heat, stirring continuously until it thickens enough to coat the back of a spoon
- Add the spices:
- Remove from heat and stir in the nutmeg, cinnamon, and vanilla extract, plus any alcohol if you're using it
- Chill thoroughly:
- Pour into a glass pitcher or bowl and refrigerate for at least one hour, though overnight is even better
- Serve it up:
- Pour into chilled glasses and top with whipped cream and an extra dusting of nutmeg
Last year my sister who never diets asked for the recipe before she even finished her first glass, and now she makes it for her keto friends every Sunday during December. It's become the thing we all look forward to when the temperature drops below freezing.
Making It Extra Special
Blend the chilled eggnog for 30 seconds before serving to create that frothy, coffee shop style foam on top. I learned this trick from a bartender friend who said the aeration actually makes the spices taste more pronounced.
Dairy Free Adaptations
Coconut cream works surprisingly well as a heavy cream substitute, though it does add a subtle tropical note that some people actually prefer. Just make sure you're using full fat canned coconut cream, not the carton kind meant for drinking.
Serving Suggestions For Gatherings
Set up a little eggnog station with different garnishes so guests can customize their drinks. Cinnamon sticks, star anise, and even a little orange peel make beautiful and flavorful additions.
- Chill your glasses in the freezer for 15 minutes before serving
- Grate fresh nutmeg over each serving right at the table
- Offer a shot of dark rum on the side for guests who want to spike their own
There's something magical about standing in a warm kitchen with a cup of this while snow falls outside, knowing you're not missing out on anything this holiday season.
Recipe Q&A
- → Can I make this eggnog dairy-free?
-
Absolutely. Swap the heavy cream for full-fat coconut cream. The texture remains luxuriously thick, though you may notice a subtle coconut undertone that pairs beautifully with the warm spices.
- → How long does keto eggnog keep in the refrigerator?
-
Store your eggnog in an airtight container and it will stay fresh for 3-4 days. Give it a good whisk or quick blend before serving, as natural separation may occur during chilling.
- → What's the best keto sweetener to use?
-
Powdered erythritol dissolves seamlessly into cold liquids, but you can also use monk fruit blends, allulose, or liquid stevia. Powdered sweeteners prevent any grittiness in the final pour.
- → Is it safe to use raw eggs?
-
This recipe uses tempering and gentle cooking to pasteurize the eggs, making it perfectly safe. If you prefer, use pasteurized eggs from the grocery store for completely raw preparations.
- → Can I freeze keto eggnog?
-
Freezing isn't recommended as the texture may separate and become grainy upon thawing. However, you can prepare the base a day in advance and keep it chilled—flavors actually develop beautifully overnight.
- → How do I make it extra frothy?
-
After chilling, blend the mixture on high speed for 30-60 seconds. This aerates the eggnog, creating a light, frothy texture that feels even more indulgent when poured into glasses.
