Instructions

1. Add the butter and the maraschino cherry juice 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 cherry juice together on medium speed until thoroughly combined (about 2 minutes.)  You really want the cherry flavor to meld with the butter to enhance the flavor of the frosting. 
3. Use a spatula to scrape the butter mixture down from the sides of the bowl.  
4. Add the Powdered Sugar to the mixing bowl.
5. Start your mixer (or electric beater) on the lowest setting and keep it on low until the marshmallow fluff/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 so the frosting gets light and fluffy.
6. Add the cornstarch to the frosting and mix until combined. This will thicken the frosting and counteract the moisture of the cherry juice without adding any extra flavor.
7. Finely dice 8-10 Maraschino Cherries. 
8. Fold the cherries into the frosting with a spoon.
