Follow these simple steps to create perfect Crème Brûlée French Toast:

1. Prepare the Bread: Arrange the slices of challah or brioche in a single layer in a baking dish.
2. Make the Custard: In a large bowl, whisk together eggs, milk, heavy cream, granulated sugar, vanilla extract, salt, and cinnamon until smooth.
3. Combine Mixtures: Pour the egg mixture evenly over the bread slices, making sure each slice is soaked well.
4. Chill: Cover the baking dish with plastic wrap and refrigerate for at least 1 hour, allowing the bread to absorb the custard. Overnight is ideal for optimal flavor.
5. Preheat the Oven: Heat your oven to 350°F (175°C).
6. Bake: Remove the plastic wrap. Bake the French toast in the preheated oven for 25-30 minutes, or until puffed and golden.
7. Caramelize the Sugar: Sprinkle brown sugar evenly over the top of the baked French toast. Use a kitchen torch to caramelize the sugar until it forms a crispy, golden crust. If you don’t have a kitchen torch, you can broil it for a few minutes, watching closely to avoid burning.
8. Serve Immediately: Allow the Crème Brûlée French Toast to cool slightly before serving.
