Bake cupcakes according to directions using a boxed cake mix, or buy pre-made cupcakes.
Pipe the white frosting onto the cupcakes, and then set aside.
Spray the sugar cones with the red color mist as you see in the photo. Set aside to dry.
Once the sugar cones (Santa hats) are dry, place a dot of frosting on a mini marshmallow, and place on top of the cone.
Set the sugar cone on top of the white frosted cupcake.
Enjoy your Santa Hat cupcakes!
