Instructions

Grease a 9×13-inch baking dish with butter or cooking spray.
Spread the cubed bread evenly in the dish.
In a large mixing bowl, whisk together eggs, milk, cream, granulated sugar, brown sugar, vanilla, cinnamon, and salt.
Pour the mixture evenly over the bread cubes, pressing down slightly to soak all the bread. Cover with plastic wrap and refrigerate overnight.
In the morning, preheat the oven to 350°F (175°C).
For the topping, mix flour, brown sugar, cinnamon, and salt in a bowl. Cut in the butter with a fork or pastry cutter until the mixture resembles coarse crumbs.
Sprinkle the topping evenly over the soaked bread.
Bake for 45–50 minutes, or until the top is golden and the center is set.

Let it cool for 5–10 minutes before serving. Enjoy warm with syrup or fresh fruit.

Notes

You can swap brioche or challah for a richer texture.
Add chopped nuts or berries before baking for extra flavor.

To make it dairy-free, use almond milk and coconut cream, and vegan butter for the topping.
