Prepare the Custard Mixture
- In a medium pan, whisk together the eggnog, whole milk, bourbon vanilla extract, teaspoon cinnamon, nutmeg, and butter on medium heat. Simmer for 5 minutes.
- Set the milk mixture aside to cool while you prepare the bread.
Chop the Bread
- Use day-old bread for best results. Cut the brioche bread into 1-inch cubes and layer half of them into a parchment-lined baking dish.
Add the Eggs to the Custard
- Whisk the large eggs into the cooled custard mixture, ensuring it’s well combined.
Assemble the Casserole
- Sprinkle half of the cinnamon sugar mixture over the first layer of bread.
- Add the remaining bread cubes and gently press them down.
- Pour the custard mixture evenly over the bread, ensuring every piece is soaked. At this point, let it sit on the counter for 30 minutes or overnight in the fridge.
Make the Crumble Topping
- In a medium bowl, combine the flour, remaining cinnamon sugar, and cold butter. Blend in a blender until nice and crumbly.
- Sprinkle the crisp topping evenly over the casserole.
Bake the Casserole

- Place the casserole in the preheated oven and bake for 35 minutes, or until the top is golden brown and the custard is set.

Serve and Enjoy
- Drizzle the bourbon syrup over the casserole before serving.
