While the cake is baking, in the bowl of a stand mixer fitted with a whisk attachment (or using a hand mixer in a large bowl), beat the butter until light and fluffy, about 3 minutes. Gradually add the powdered sugar, one cup at a time, beating well after each addition. Add 6 tablespoons of maraschino cherry juice and beat until the frosting is light and fluffy.

Once the cake is cool, frost with the cherry buttercream and garnish with remaining cherries.
