What could be more cozy than a steaming mug of hot cocoa topped with homemade marshmallows? We can't think of much that outdoes that. It's a fun project to work on with kids (but be careful of the boiling sugar; adults only!), especially in the dregs of winter. Take a look at the video for the whole recipe; it couldn't be simpler, and the result is sure to wow everyone who gets a taste.
