Make cupcakes following directions on the box. Allow to cool.
Using a small spatula, spread the white cake frosting evenly on the sugar cone.
Pick out the red pieces of Malt-O-Meal Colossal Berry Crunch cereal and place them on the cone. Take one marshmallow and add a dab of white cake frosting to the end. Place on top of the cone.
Place the finished cone on top of the cupcake, and press down gently.
Enjoy!
