It's easy to toast marshmallows without a campfire. Line up marshmallows on a baking sheet and broil in the oven until the tops are toasted golden brown. Remove the tray from the oven, turn over the marshmallows, return the tray to the oven and toast that side until golden brown. Add toasted marshmallows to a bowl of chocolate pudding and crushed-up graham crackers for a fun take on s'mores.
