Christmas Tree Cupcakes

If necessary, slice the tops off of the cupcakes to create a flat surface. Slather a small portion of the frosting on the cupcakes to create a base atop which to position the sugar cone tree. Stir the food coloring into the remaining frosting, adding more food coloring as necessary to achieve your desired green color. Apply a thin layer of frosting on the exteriors of the sugar cones. Transfer the remaining frosting to a pastry bag fitted with the star-shaped pastry tip. Place the sugar cones atop the cupcakes then pipe leaves onto the trees. Garnish with the edible silver ball sprinkles and dust with powdered sugar.
