Overnight Brioche French Toast with streusel topping may be served for brunch or dessert! Easy to make, and bakes up similar to bread pudding.
Spray or coat a 9"x13" or other comparable casserole dish with cooking oil or butter.
Tear or cut bread into large pieces, place into prepared pan. The pieces will be squished together; it is ok to layer the pieces a bit.
Using a whisk or blender, Mix eggs, half and half, milk, sugars, cinnamon and vanilla until combined.
Pour mixture over bread in casserole dish. Push the pieces down if they begin to float!
Cover with Saran Wrap or foil and place overnight in the refrigerator.
Mix the streusel topping, place in a bowl and refrigerate until ready to bake.
When ready to bake, remove foil and preheat the oven to 350 degrees with the rack in center of the oven. Top with streusel, and bake uncovered for 45-55 minutes. The egg should be cooked, and not runny or wet looking.
Sprinkle generously with powdered sugar and top with fresh fruit, syrup, or serve plain.
