If you're making cupcakes for a party and you need to leave now you can skip the few minutes it takes to ice them by adding a marshmallow to the top of each cupcake five minutes before the end of the baking period.
Household blogger Toni Pilsbury offers the marshmallow tip, noting that after five minutes in the oven the marshmallows will be spreadable and will give an interesting twist on cupcakes. Simple but effective.
