Making Overnight Crème Brûlée French Toast is a straightforward process. Follow these easy steps for a delicious result:

1. Prepare the Bread: Slice the brioche or challah bread thickly and arrange the slices in a greased 9×13 inch baking dish. Overlap if necessary.
2. Whisk Eggs and Dairy: In a large bowl, whisk together the eggs, heavy cream, whole milk, granulated sugar, vanilla extract, ground cinnamon, and salt until well combined.
3. Soak the Bread: Pour the egg mixture evenly over the bread slices, ensuring they are well coated. Press down gently to help the bread absorb the liquid.
4. Cover and Refrigerate: Cover the baking dish with plastic wrap and refrigerate overnight. This allows the flavors to meld and the bread to soak thoroughly.
5. Preheat Oven: On the day of serving, preheat your oven to 350°F (175°C).
6. Add Brown Sugar: Remove the plastic wrap and sprinkle brown sugar evenly over the top of the soaked bread.
7. Bake: Place the baking dish in the preheated oven and bake for 30-35 minutes, or until the top is golden brown and a knife inserted into the center comes out clean.
8. Cool Slightly: Once baked, let it cool for a few minutes before serving to allow the custard to set.
9. Serve Warm: Slice and serve warm, garnished with fresh berries or sliced bananas if desired.
