Warm Keto Eggnog with Vanilla (Alcohol-Free)
Eggnog, sometimes called egg punch and similar in spirit to German Eierlikör, is a classic winter drink made from eggs, milk, and sugar, often spiked with rum. The keto-friendly version uses cream instead of milk, erythritol instead of sugar, and skips the alcohol entirely, so you can enjoy it sober. The egg yolks make the drink thick and rich while delivering lecithin, vitamin A, and choline. Per cup: 3 g net carbs, 32 g fat, 9 g protein.

Preparation
Pour 100 ml cream and 100 ml water into a small saucepan. Slit a vanilla pod lengthwise, scrape out the seeds, and add both the seeds and the empty pod to the cream. Heat over medium heat to about 70 °C, do not boil. Meanwhile, whisk 2 egg yolks with 1 tbsp erythritol in a bowl for 1 minute until the mixture lightens and turns frothy. Slowly pour the warm cream into the egg yolks while whisking constantly, never the other way around, otherwise the yolks will curdle. Return the mixture to the pan and warm gently while stirring until it thickens slightly (around 80 °C, the classic "coating the back of a spoon" stage). Remove from the heat, take out the vanilla pod, pour into a prewarmed cup, and dust with freshly grated nutmeg.
Why this eggnog fits keto
Traditional eggnog often contains 20 to 30 g of sugar per cup. Sweetened with erythritol, this drink stays at around 3 g net carbs, all from the cream and egg yolks. One egg yolk (approx. 18 g) delivers about 5 g fat, 3 g protein, and only 0.5 g carbs. Heavy cream with 32 % fat is one of the few dairy products that fits comfortably in keto thanks to its very low carb content. Real vanilla seeds (not flavored extracts with added sugar) round out the sweetness without adding carbs.

How can I vary the eggnog?
Classic rum flavor: add 2 drops of alcohol-free rum extract for that traditional taste without the booze. Cold as eggnog: let it cool completely, chill in the fridge for 1 hour, and serve over ice. Overnight it thickens even further. Chocolate eggnog: whisk 1 tsp unsweetened cocoa powder into the egg yolks together with the erythritol for a cross between eggnog and hot chocolate. With cinnamon: steep half a cinnamon stick alongside the vanilla. For 2 servings: double the quantities. Whipping the mixture in a larger bowl over a water bath makes it frothier, almost like a warm zabaglione.
Tips for foolproof eggnog
- Warm the cream but never boil it, otherwise the yolks curdle when combined.
- Whisk the yolks with erythritol beforehand for a more stable binding.
- Keep the temperature below 85 °C while thickening, or the eggs will scramble.
- Use very fresh eggs because the yolks are only gently heated.
- Grate the nutmeg just before serving so the aroma stays bright.

FAQ
Is this eggnog risky because of the raw eggs?
The yolks are heated to around 80 °C during thickening, which effectively pasteurizes them, so the salmonella risk is minimal. Pregnant women and people with weakened immune systems should opt for pasteurized egg yolks from a carton.
Can I make the eggnog ahead of time?
Yes, the finished drink keeps in the fridge for 24 hours. Reheat gently before serving (max. 70 °C) and whisk briefly to bring back the foam. Do not bring it back to a boil.
Which sweetener works best here?
Erythritol dissolves well when warm. Allulose would be even closer to real sugar but is hard to find in many markets. Stevia thins out the mouthfeel because it lacks the bulk that erythritol provides.
