Creating Croissant French Toast Bake is straightforward if you follow these simple steps:

1. Preheat the Oven: Preheat your oven to 350°F (175°C) and grease a 9×13-inch baking dish.
2. Prepare the Croissants: Cut the croissants into quarters and arrange them in the greased baking dish, making sure to fill it evenly.
3. Make the Custard Mixture: In a large bowl, whisk together the eggs, whole milk, heavy cream, granulated sugar, vanilla extract, ground cinnamon, and salt until well combined.
4. Combine: Pour the custard mixture evenly over the croissant pieces, pressing down gently to ensure they soak up the liquid.
5. Let it Rest: Allow the mixture to sit for about 30 minutes, or cover it and refrigerate overnight for a richer flavor.
6. Bake: Place the baking dish in the preheated oven and bake for 30-35 minutes, or until the top is golden brown and the custard is set.
7. Cool: Remove from the oven and let it cool for 10-15 minutes before serving.
8. Dust with Powdered Sugar: Just before serving, dust the top with powdered sugar for a beautiful finish.

These steps will guide you in creating this delicious croissant bake effortlessly.
