# Method:
01 - Grease a 9x13-inch baking dish with butter or nonstick spray.
02 - Arrange half of the cubed bread evenly in the prepared dish.
03 - In a large bowl, whisk together mashed bananas, eggs, milk, cream, brown sugar, granulated sugar, vanilla, cinnamon, nutmeg, and salt until smooth and fully combined.
04 - Pour half of the custard mixture over the bread cubes, pressing gently to ensure even saturation.
05 - In a medium bowl, beat softened cream cheese, sugar, egg yolk, and vanilla until smooth and creamy. Dollop by spoonfuls over the soaked bread layer.
06 - Top with remaining bread cubes, then pour remaining custard over the top. Gently press to ensure all bread is thoroughly moistened.
07 - Mix melted butter, brown sugar, and cinnamon in a small bowl. Drizzle or dot the mixture evenly over the casserole.
08 - Cover tightly with plastic wrap or foil and refrigerate overnight, minimum 6 hours, ideally 8 hours.
09 - Preheat oven to 350°F. Remove casserole from refrigerator while oven reaches temperature.
10 - Bake uncovered for 40-45 minutes, until puffed and golden brown and a knife inserted in the center comes out clean.
11 - Cool for 10-15 minutes before serving. Serve warm, optionally with maple syrup or a dusting of powdered sugar.
