Reindeer food is a special blend of oats, hay, and molasses that we love to eat on Christmas Eve. To make your own reindeer food, mix equal parts oats and hay together in a bowl. Then, add a few spoonfuls of molasses and stir well until it's all combined. That's it! Your very own homemade reindeer food. Just sprinkle it outside on Christmas Eve and watch as the reindeer flock to it.
