How many calories are in a cup of eggnog?

Quick answer

A cup of regular eggnog is roughly 343 calories with 19 g of fat, according to one nutrition database (FatSecret). That is a typical figure, not an exact one: brands and homemade recipes differ, and a splash of rum or brandy adds more. The Nutrition Facts label on your carton is the number to trust.

How many calories are in a cup of eggnog?

For regular eggnog, the nutrition database FatSecret lists 343 calories, 19 g of fat, about 34 g of carbohydrate and about 10 g of protein in 1 cup. That is about 135 calories per 100 g. Treat it as a typical figure: carton eggnog varies by brand, and homemade eggnog depends on how much cream, egg yolk and sugar you use.

Why the number varies

  • Dairy: Eggnog made mostly with cream is higher than eggnog made with milk. The same database has a separate entry for a 2% milk version, so check which one you are looking at.
  • Sugar: Sweeter recipes add calories quickly.
  • Alcohol: Rum, brandy or bourbon add calories on top of the eggnog itself. The amount depends on how much you pour.
  • Serving size: The serving on a carton may be smaller than a full mug. Check the serving size line before you multiply.

These are third-party database numbers, not a lab test, so use them for planning only.

How to check your own

  1. Find the serving size on the label.
  2. Multiply the calories by the number of servings you pour.
  3. Add the calories of any alcohol you stir in.

Ways to lighten it

  • Serve a smaller glass
  • Choose a reduced-fat carton and compare the label
  • Mix half eggnog with cold milk
  • Top with cinnamon or nutmeg instead of whipped cream

Food safety note

Homemade eggnog made with raw eggs carries a food-poisoning risk, so use pasteurized eggs or a cooked recipe, and keep it cold.
