Creating this Chocolate Croissant Breakfast Bake can be straightforward if you follow these simple steps:

1. Preheat Oven: Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish.
2. Prepare Croissants: Cut the chocolate croissants into quarters and place them evenly in the prepared baking dish.
3. Whisk Eggs: In a large bowl, whisk together the eggs until well beaten.
4. Combine Milk and Cream: Add the whole milk, heavy cream, granulated sugar, vanilla extract, ground cinnamon, and salt to the eggs. Mix until fully combined.
5. Pour Mixture: Pour the custard mixture evenly over the croissant pieces, ensuring they are well soaked.
6. Let Soak: Allow the mixture to sit for about 15 minutes to let the croissants absorb the custard.
7. Bake: Place the baking dish in the preheated oven and bake for 40-45 minutes, or until the top is golden brown and a knife inserted in the center comes out clean.
8. Cool: Remove from the oven and let it cool for about 10-15 minutes.
9. Dust with Sugar: Before serving, dust the top with powdered sugar if desired.
10. Garnish: Serve warm, garnished with fresh berries for a pop of color.
