In a medium bowl, combine the cinnamon and the applesauce until a soft dough forms.
1 cup ground cinnamon, ¾ cup applesauce
Roll the dough out until it is about ¼-inch thick.
Use cookie cutters to carefully cut shapes out of the dough.
Transfer the pieces to a baking sheet and use a straw or toothpick to make holes (to add string to hang the ornaments).
Continue re-rolling the dough and cutting out shapes until you have used all of the dough.
Allow the ornaments to dry completely by either leaving them at room temperature for 24 hours or baking for 2 hours at 200°F.
Run string or ribbon through the holes and hang your ornaments on your tree.
Notes
These ornaments aren't made to be eaten, but they're also non-toxic. If your little one takes a bite, it won't be the end of the world, but they also probably won't enjoy it too much.
You can use inexpensive generic cinnamon! No need to break out the fancy stuff for this easy craft.
Have fun with several different festive cookie cutters!
Storage: Store cinnamon ornaments in an airtight container or Ziplock bag in a cool, dry place for up to 1 year.
