Ingredients
  

1 loaf of challah bread (or brioche), cut into 1-inch cubes

6 large eggs

2 cups whole milk

1 cup heavy cream

3/4 cup brown sugar, packed

1 teaspoon vanilla extract

1 teaspoon ground cinnamon

1/2 teaspoon nutmeg

1/4 teaspoon salt

1 cup mixed berries (blueberries, strawberries, or raspberries)

1/2 cup maple syrup (for serving)

Powdered sugar (for dusting, optional)

Instructions
 

Prepare the Bread: In a large mixing bowl, combine the bread cubes with the mixed berries, tossing gently to ensure even distribution. Place the mixture into a greased 9x13 inch baking dish.

    Make the Egg Mixture: In a separate bowl, whisk together the eggs, whole milk, heavy cream, brown sugar, vanilla extract, cinnamon, nutmeg, and salt until well blended.

      Combine: Pour the egg mixture evenly over the bread and berry mixture, pressing down gently to ensure all bread is soaked. Cover the baking dish with plastic wrap and refrigerate overnight (at least 6 hours) to allow the bread to absorb the custard.

        Preheat Oven: The next morning, preheat your oven to 350°F (175°C).

          Bake: Remove the casserole from the refrigerator and let it sit at room temperature for about 20 minutes. Bake uncovered for 45-50 minutes, or until the top is golden brown and the center is set.

            Serve: Let the casserole cool for a few minutes before cutting it into squares. Serve warm drizzled with maple syrup and a dusting of powdered sugar, if desired.
