Instructions

1. Add the butter and the peppermint extract 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 peppermint extract together on medium speed until thoroughly combined (about 2 minutes.)
3. Use a spatula to scrape the butter and vanilla mixture down from the sides of the bowl.
4. Measure 1 Pound of Powdered Sugar on a food scale. If you don’t have a food scale, measure 4 cups instead.
5. Add the powdered sugar to the butter/peppermint 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. Taste your frosting. You are trying to determine if the consistency is correct or if it needs some milk or maybe a little more peppermint extract. If it tastes great, test the consistency. Too thick? Add 1 teaspoon of milk and mix again to check to see if it is now the right consistency.  The amount of milk 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 milk a teaspoon at a time. You can check out our FAQ section below to see some other advice on making the perfect batch of frosting.
