Preheat oven to 350. Line a 12-cup cupcake tin with cupcake liners.

Prepare cake batter according to package instructions. Fill each cupcake liner about two-thirds full with batter and bake until a toothpick inserted into each cupcake comes out clean, about 20 minutes. Let cool completely.

Make the frosting: Combine powdered sugar and butter in a large bowl. Beat with a hand mixer until smooth and fluffy. If the mixture is too thick, beat in milk.

Using an ice cream scoop, scoop frosting onto cooled cupcakes. Drizzle with chocolate syrup then garnish with sprinkles and cherries.
