Step 1

Preheat oven to 350.

Step 2

Combine heavy cream, milk, nutmeg, cinnamon, vanilla extract, white granulated sugar and eggs into a bowl.  Whisk until combined and set aside.

Step 3

Coat a medium sized baking dish with butter.

Step 4

Cut brioche loaf into small cubes.  Place in baking dish, evenly layering bread.

Step 5

Pour cream and egg mixture evenly over the cubed bread ensuring that each piece is covered with the mixture.  (Tip:  Leave the casserole in the fridge over night before baking so the egg mixture can really soak in to the bread)

Using a separate bowl for the crumb coating, combine brown sugar, flour and butter into bowl.  Using a fork combine the ingredients and break the butter up into small pieces.  Pour crumb coating mixture over the top of the french toast, spreading evenly.
