In a large bowl, whisk together the eggs, milk, brown sugar, vanilla, cinnamon, and salt. Stir in the bread until fully coated. Spoon into the prepared baking dish.

Step 3

In a small bowl, whisk together the brown sugar, cinnamon, and salt. Sprinkle the mixture and the butter evenly over the bread mixture.

Step 4

Bake for about 30 minutes or until the filling is set and the top is golden brown. Cool for a few minutes before serving. Serve with powdered sugar and maple syrup, if desired.
