This homemade spiked eggnog combines rum and whiskey with whipped egg yolks, sweetened condensed milk, and warm spices for a rich, creamy holiday drink that's leagues better than anything you'll find in stores. The Angostura bitters add subtle complexity while the alcohol acts as a preservative, keeping it fresh in the refrigerator for up to a month. Make it one to two weeks ahead so the flavors can meld together beautifully. Serve over ice with a dusting of cinnamon for a festive touch that will have guests asking for the recipe.
In the bowl of a stand mixer fitted with a whisk attachment, whisk the yolks on high for about 20 minutes until light in color and thick and fluffy.
Mix in the grated nutmeg.
In a separate bowl, combine all the milks.
Add the milks to the yolks in 4 batches, mixing on low speed.
Add the Angostura bitters and vanilla extract and mix until incorporated.
Add the rum and whiskey and mix well.
Transfer to glass bottles and refrigerate overnight before serving. Serve over ice and optionally sprinkle with cinnamon for garnish.
Notes
This recipe uses raw egg yolks, which can carry a risk of Salmonella. Use pasteurized eggs when possible.If using regular eggs and you want to reduce risk while keeping the eggs fluffy, you can temper the eggs by gently warming the milk mixture to about 110–120 °F and slowly adding it to the whipped yolks while whisking constantly. This warms the eggs enough to reduce bacterial risk without compromising their fluffy texture.
