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

Chop the stale bread into 1-inch cubes and evenly spread them across the bottom of the greased baking dish.

In a mixing bowl, whisk together eggs, milk, sugar, vanilla extract, cinnamon, and salt until smooth.

Pour the custard mixture over the bread cubes and gently press down to help it soak. Let it rest for 10 minutes.

Drizzle the melted butter over the top and bake uncovered for 40 minutes or until golden brown.

Let it cool for about 10 minutes before serving warm with maple syrup and fresh berries.
