Preheat your oven to 350°F (175°C) and grease a 9x13-inch baking dish with butter.

Layer half of the cubed French bread in the baking dish.

Scatter half of the cream cheese cubes and half of the sliced strawberries over the first layer of bread.

Repeat layering with remaining bread, cream cheese, and strawberries.

In a large bowl, whisk together eggs, whole milk, heavy cream, granulated sugar, light brown sugar, vanilla extract, ground cinnamon, and salt until smooth.

Pour custard mixture over layered bread, pressing down gently to absorb.

Allow the dish to rest for 15 minutes or refrigerate overnight for deeper flavor.

Bake uncovered for 45-50 minutes until golden brown and center is set.

Cool for about 10 minutes before dusting with powdered sugar and serving.
