I learned how to make this rich, gooey, caramel-ly version of French Toast when I lived in Louisiana. It is very sweet - feel free to decrease the amount of sugar if you wish. There is no milk in this version. If you don't have a good nonstick pan, you may need to grease your pan with some oil or butter rather than the nonstick spray, as the sugar caramelizes and can be a little messy to clean.
An unusual name for a breakfast recipe, I know. The name comes from the way this French toast looks when it is baked - it is baked whole, with cuts down the center marking off each serving slice - giving it the appearance of a hedgehog...well, sort of...you have to use your imagination.
