Instructions

1. Add the butter and the eggnog to a mixing bowl. The butter needs to be what we call, slightly softened which is somewhere between straight out of the refrigerator and room temperature.
2. Mix the butter and the eggnog together on medium speed until thoroughly combined (about 2 minutes.)  The goal is to get the eggnog to meld with the butter to enhance the flavor of the frosting.
3. Use a spatula to scrape the butter and eggnog mixture down from the sides of the bowl.  
4. We use a food scale to measure 1 Pound of Powdered Sugar.  If you don’t have a food scale, measure 4 cups instead. We normally do not sift the powdered sugar and instead rely on the mixer to do that work for us.
5. Add the powdered sugar to the butter/eggnog mixture in the mixing bowl.
6. Start your mixer (or electric beater) on the lowest setting and keep it on low until the butter and sugar are incorporated (about 30 seconds). Stop the mixer and scrape down the sides of the bowl and then increase the speed to medium-high and mix for another 30-45 seconds until the frosting is light and fluffy.
7. Add the nutmeg and mix again until just combined.
8. Taste your frosting. You are trying to determine if the consistency is correct or if it needs a little more eggnog or nutmeg. If it tastes great, test the consistency.  Too thick? Add 1 teaspoon of eggnog and mix again to check to see if it is now the right consistency.  The amount of eggnog to use depends on the state of your frosting and sometimes the time of year (if it is a hot humid day, you might not need to add any milk.) A good rule of thumb is to add the eggnog a teaspoon at a time.
