In a large mixing bowl, whisk together eggs, milk, cream, sugar, vanilla, and cinnamon.
Layer the bread slices in a greased baking dish.
Pour the egg mixture over the bread, ensuring all slices are soaked.
Cover the dish with plastic wrap and refrigerate overnight.
Preheat the oven to 350°F (175°C) the next morning.
Remove the plastic wrap and bake the french toast for 30-35 minutes.
Check for a golden-brown top and a custardy center.
Let it cool slightly before serving.
Top with fresh berries and a drizzle of maple syrup.
Serve warm and enjoy!
