In case you're wondering, "What in the world are ninjabread cookies?!" it's the same recipe as gingerbread cookies, but with ninjabread men/ahem women cookie cutters. We will usually incorporate them with more traditional cookie cutters as well - candy canes, people shapes, snowflakes...sometimes hearts and dog bones because...littles.
Quite honestly, I either buy the gingerbread cookie mix that is everywhere this time of year, or if I didn't plan accordingly, we usually have what we need to make it from scratch. I like Martha Stewart's Basic Gingerbread Cookie recipe.
It's an easy and fun (not to mention delish) way to spend a snowy afternoon at home and you end up with gifts for friends and family that come by!
