Place the piping bag into a large glass and fold the sides of the bag over the rim of the glass. Scoop the vanilla frosting into the piping bag.
Bring the pastry bag edges up and twist them together to start decorating. Add your star tip.
If you don’t have a piping bag, try a plastic bag with the tip snipped off and star tip added. Frost the cooled and filled cupcakes.
Top cupcakes with one cherry and some sauce from the pie filling.
