Follow The Directions

01

Step

Preheat oven to 350 degrees F (175 degrees C). (5 minutes)

02

Step

In a medium bowl, combine brown sugar, flour, melted butter, salt, and 1/2 teaspoon of the cinnamon. Mix until a crumbly streusel forms. Set aside. (5 minutes)

03

Step

Lightly grease a 9x13 inch baking dish with cooking spray. (2 minutes)

04

Step

In a large bowl, whisk together milk, heavy cream, eggs, maple syrup, vanilla, and the remaining 1 1/2 teaspoons of cinnamon until well combined. (3 minutes)

05

Step

Add the cubed brioche to the milk mixture, gently tossing to ensure all pieces are moistened. The bread will be saturated, but may not absorb all the liquid. (5 minutes)

06

Step

Transfer the brioche mixture to the prepared baking dish. Sprinkle evenly with granulated sugar. (2 minutes)

07

Step

Evenly distribute the cinnamon streusel topping over the brioche mixture. (2 minutes)

08

Step

Allow the casserole to stand at room temperature for 10 minutes before baking. (10 minutes)

09

Step

Bake in the preheated oven for 35 to 40 minutes, or until the casserole is set, golden brown, and puffed up. (40 minutes)

10

Step

Remove from the oven and let cool slightly before serving with additional maple syrup. (5 minutes)

For an extra layer of flavor, consider adding a splash of bourbon or rum to the custard mixture.
If you don't have day-old brioche, you can dry out fresh brioche cubes in a low oven (200°F) for about 30 minutes before assembling the casserole.
Feel free to customize the streusel topping with chopped nuts like pecans or walnuts.
Leftovers can be stored in the refrigerator for up to 3 days. Reheat gently in the oven or microwave.
