Preheat the oven to 175°C and grease a 23x33 cm baking dish.

Tear croissants into chunks and place half of them evenly in the baking dish. Scatter half of the chocolate chips over this layer. Repeat with the remaining croissants and chocolate chips to create two layers.

In a mixing bowl, whisk together the eggs, whole milk, heavy cream, granulated sugar, vanilla extract, ground cinnamon, and salt until the mixture is smooth and homogeneous.

Pour the custard mixture evenly over the croissant layers, pressing down lightly to ensure absorption. Allow the dish to sit at room temperature for 20 to 30 minutes or refrigerate overnight for enhanced custard infusion.

Bake uncovered for 35 to 40 minutes until the top is puffed and golden brown. If browning too quickly, loosely tent the dish with foil to prevent burning.

Remove from oven and let rest for 10 minutes before slicing. Dust with powdered sugar and garnish with fresh berries if desired. Serve warm.
