Ingredients

• 1 loaf Challah bread (or brioche, cubed)
• 8 large Eggs
• 2 cups Milk
• 1 cup Heavy cream
• 1 cup Granulated sugar
• 0.5 cup Brown sugar
• 1 tablespoon Vanilla extract
• 1 teaspoon Ground cinnamon
• 0.25 teaspoon Nutmeg (optional)
• 4 tablespoons Butter (melted)
• 0.25 cup Powdered sugar (for garnish)
• 0 optional Maple syrup (for serving)

Directions

Step 1

Grease a 9x13-inch baking dish with butter or non-stick spray.

Step 2

Cut the challah bread into 1-inch cubes and evenly distribute them in the prepared baking dish.

Step 3

In a large mixing bowl, whisk together eggs, milk, heavy cream, granulated sugar, brown sugar, vanilla extract, cinnamon, and nutmeg (if using).

Step 4

Pour the egg mixture evenly over the bread cubes, ensuring all pieces are coated.

Step 5

Cover the dish with plastic wrap or aluminum foil and refrigerate for at least 3 hours or overnight to allow the bread to soak up the custard mixture.

Step 6

Preheat the oven to 350°F (175°C).

Step 7

Remove the plastic wrap or foil from the casserole dish. Drizzle the melted butter evenly over the top.

Step 8

Bake the casserole uncovered for 40-45 minutes, or until the top is golden brown and the custard is set.

Step 9

Let the casserole cool for 5-10 minutes before serving.

Step 10

Dust with powdered sugar and serve warm with maple syrup, if desired.
