S’mores French Toast Casserole
As we were dealing with the unexpected disappointment, it occurred to me that we should just turn my tried and true Overnight French Toast Bake into a s’mores version! So that’s exactly what we did!
If you love s’mores, too, then I recommend making Golden Graham S’mores Bars , Frozen S’mores , S’mores Bars , S’mores Brownie Bars , S’mores Candy Bites , or S’mores Mini-Pudding Pies , too!

What You’ll Need
1 loaf Sour Dough Bread
8 Eggs
2 cups Milk
1/2 cup Heavy Cream
3/4 cup Sugar
2 tbsp Vanilla
1/2 cup Flour
1/2 cup Brown Sugar
1 tsp Cinnamon
1/4 tsp Salt
1/2 cup Cold Butter, Cut into Pieces
Mini-Marshmallows
Chocolate Chips

How to Make Overnight French Toast Bake
Spray 9 x 13 pan with non-stick spray.
Cut a loaf of sour dough bread into cubes and distribute evenly into the pan.
In a bowl, mix together 8 eggs, 2 cups milk, 1/2 cup heavy cream, 3/4 cup sugar, and 2 tbsp vanilla.
Pour over bread evenly. Cover pan and refrigerate overnight.
For the topping, mix together 1/2 cup flour, 1/2 cup brown sugar, 1 tsp cinnamon, and 1/4 tsp salt.
Cut 1/2 cup cold butter into pieces and mix with the topping mixture until crumbly. Place into a separate container and refrigerate overnight.
Take the pan and container out of the refrigerator when ready. Sprinkle the crumbly topping over the bread evenly.
Bake at 350 degrees for 45 minutes. (Remove from the oven if you like it soft; continue to bake if you like it firm.)
Set oven to broil.
Sprinkle the top with desired amount of mini-marshmallows, chocolate chips, and crushed Graham crackers.
Broil for 1-2 minutes. Watch the entire time and remove from oven just as the mini-marshmallows start to turn golden brown.

Bread – Make sure to use bread that is a day or two old. This helps to make sure it doesn’t absorb too much and become soggy. I highly recommend using sour dough bread!
Variations – You can add chopped pecans, apple pieces, or blueberries!
Full Pan – Make sure your pan is filled just about to the top, not heaping, with the cubed sour dough bread. Depending on the size of the loaf you buy, you may need a loaf and a half. Making sure the pan is full helps with not having soggy French toast.
