Coat a 9x13-inch baking dish with cooking spray.

Place half of the cinnamon raisin bread cubes in the prepared dish. Sprinkle cream cheese evenly over the bread layer and top with diced apples. Add the remaining bread cubes on top.

In a large bowl, beat half-and-half, eggs, melted butter, and maple syrup together. Pour this mixture evenly over the bread layers. Cover the baking dish with plastic wrap and press down to ensure all the bread pieces are soaked. Refrigerate the mixture for at least 2 hours.

Preheat the oven to 325°F (165°C).
