great idea : marshmallows as cupcake frosting

I saw this idea in September's Real Simple and thought the suggestion sounded good enough to try next time I bake cupcakes.

When your cupcakes have about three minutes left to bake, pull out the tin and place one marshmallow on top of each cupcake. Return the tin to the oven for the remaining time or until the marshmallows are slightly melted but still fluffy.
