Step 1: Prepare the Dish
- Grease a 9x13-inch baking dish with butter or nonstick spray. Add the bread cubes evenly.

Step 2: Make the Custard
- In a large bowl, whisk eggs, milk, heavy cream, both sugars, vanilla, cinnamon, nutmeg, and salt until smooth.

Step 3: Assemble
- Pour the custard evenly over the bread. Press gently so all the bread absorbs the liquid.

Step 4: Chill
- Cover and refrigerate for at least 4 hours or overnight for best results.

Step 5: Make Topping
- Mix flour, brown sugar, cinnamon, and salt. Cut in cold butter until crumbly. Keep chilled.

Step 6: Bake
- Preheat oven to 350°F (175°C). Let the casserole sit at room temp for 20 minutes. Add topping and bake 45–55 minutes until golden and set.
