Baked French Toast

One of my families favorite breakfasts is baked french toast.
I mix up my secret recipe the day before and let it sit over night marrying all the lovely flavors together. I either bake it like a casserole or I spoon it into individual ramekins and serve it as a side with bacon and eggs. I like to use brioche, challah or french bread. I serve it hot from the oven and it looks lovely like a soufflé.
