Preheat your oven to 350°F (175°C).
Grease a 9x13 inch baking dish.
Arrange the bread slices in the dish, overlapping them slightly.
In a mixing bowl, whisk together the eggs, milk, heavy cream, sugar, vanilla, cinnamon, and salt.
Pour the egg mixture evenly over the bread, ensuring all slices are soaked.
Cover the dish with plastic wrap and refrigerate for at least 1 hour, or overnight.
Remove from the fridge and let sit at room temperature for 10 minutes.
Bake uncovered for 30-35 minutes, until golden and puffed.
Let cool slightly before slicing.
Serve warm, topped with fresh berries and maple syrup.
