In a bowl, whisk together the water, powdered milk, powdered eggs, vanilla, salt, orange juice and zest and sugar.
Pour this mixture over the dried bread and cranberries.
Cover with aluminum foil and bake for 35-45 minutes or until the center seems firm and no longer soft.
While the casserole is baking you can whip the whipped topping, make some cream cheese frosting to drizzle over the top or just enjoy with maple syrup for more of a breakfast casserole.
Serve syrup or toppings over baked casserole.
If you want to make this casserole using fresh eggs, simply replace the water with 1 3/4 cup milk and 8 eggs. The rest of the recipe will be the same.
