In a mixer bowl, beat the butter for 2-3 minutes until it is creamy and almost white in appearance.
Add in the powdered sugar, melted chocolate and 2 tablespoons of cherry juice until light and fluffy. (Add in additional juice, one tablespoon at a time, until the frosting is the consistency you like.)
Gently fold in the drained chopped cherries (these should be well drained so that it doesn't add more liquid to your frosting).
Frost on cupcakes, cakes, brownies or cookies.
Refrigerate leftover frosting.
