Last Christmas I got the Ninjabreadmen Cookie Cutters - the kids love them, but I think I love them more. So of course, we had to make Ninja marshmallows. One has a little battle damage (to be expected when a three year old wields the cookie cutter) but they turned out pretty well. They taste like store bought ones, just fresher.
Next time I will try the chocolate marshmallow recipe I found in Cooking Light. We were also thinking it would be fun to put them on a stick and dip them in chocolate. Maybe add some sprinkles, sea salt, caramel, other toppings.
I got the marshmallow recipe from Bon Appetit magazine: http://www.bonappetit.com/
Like the Ninjas? The cookie cutters can be found at ThinkGeek and Amazon
