In a large, shallow bowl, mix your eggs, milk, and cinnamon and vanilla, if using. Preheat your griddle or pan over medium heat. If you aren’t using non-stick, coat with oil or butter.
Dip each piece of bread in the egg mixture and turn to coat. Cook in the hot pan until golden brown to your liking, about 2-4 minutes per side. Allow the slices to cool, and then cut each slice into 4 sticks. You can cut multiple pieces at once.
Can be stored in the freezer in a glass container or a Zip-lock freezer bag for 1-2 months.
