Creating this amazing crème brûlée French toast is easier than you might think! Follow these simple steps:

1. Prepare the Bread: Cut the brioche into thick slices, about 1 to 1.5 inches thick. Arrange the slices in a greased baking dish.
2. Make the Custard Mixture: In a large mixing bowl, whisk together the eggs, heavy cream, milk, granulated sugar, vanilla extract, cinnamon, and salt until well combined.
3. Soak the Bread: Pour the custard mixture evenly over the slices of brioche, ensuring each piece is well-coated. Allow it to soak for at least 20 minutes, or overnight in the refrigerator for best results.
4. Preheat the Oven: Preheat your oven to 350°F (175°C) while the bread soaks.
5. Bake: Place the baking dish in the oven and bake for 30-35 minutes, or until the top is golden brown and the middle is set.
6. Caramelize the Sugar: Once baked, sprinkle a thin, even layer of brown sugar over the top and use a kitchen torch to caramelize it until bubbling and golden. (Alternatively, broil it in the oven for a couple of minutes, watching closely to avoid burning.)
7. Serve: Allow the caramelized sugar to harden for a couple of minutes before slicing and serving.

Following these straightforward steps will lead you to a mouthwatering dish that is sure to impress!
