04 - 1 1/2 cups whole milk

# Cooking Steps:
01 - Grease a 9x13-inch baking dish with butter or nonstick spray.
02 - Arrange half of the cubed bread evenly across the bottom of the prepared dish.
03 - In a large bowl, whisk together mashed bananas, eggs, milk, heavy cream, brown sugar, granulated sugar, vanilla extract, ground cinnamon, nutmeg, and salt until thoroughly smooth.
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 extract until smooth and creamy.
06 - Dollop the cream cheese mixture by spoonfuls over the soaked bread layer, distributing evenly across the dish.
07 - Top with remaining bread cubes and pour the rest of the custard mixture over the top. Gently press to ensure all bread is fully moistened.
08 - Mix melted butter, brown sugar, and ground cinnamon together. Drizzle or dot the mixture evenly over the casserole.
09 - Cover tightly with plastic wrap or aluminum foil and refrigerate for a minimum of 6 hours, ideally 8 hours or overnight.
10 - When ready to bake, preheat oven to 350°F. Remove casserole from refrigerator to allow it to come closer to room temperature while oven heats.
11 - Bake uncovered for 40 to 45 minutes, until the top is puffed and golden brown and a knife inserted in the center comes out clean.
12 - Allow the casserole to cool for 10 to 15 minutes. Serve warm, optionally topped with maple syrup or a light dusting of powdered sugar.
