Ingredients:
- 6 cups (450g) cubed Challah or Brioche bread
- 4 tbsp (56g) unsalted butter, melted
- 4 large eggs
- 2 cups (480ml) half-and-half
- 1/2 cup (100g) light brown sugar, packed
- 1 tbsp (15ml) vanilla extract
- 1 tsp (2g) ground cinnamon
- 1/4 tsp (1g) ground nutmeg
- 1/4 tsp (1.5g) salt
- 3 tbsp (35g) granulated sugar
- 1 tsp (2g) ground cinnamon
- 2 tbsp (28g) unsalted butter, softened
Instructions:
- Preheat the oven to 350°F (180°C) and grease a 9x13 inch baking dish with butter or non-stick spray.
- Place the 6 cups of cubed bread in a large bowl, drizzle with 4 tbsp melted butter, and toss gently to coat.
- Spread the buttered bread cubes evenly into the prepared baking dish.
- In a mixing bowl, whisk together 4 large eggs and 1/2 cup packed light brown sugar until smooth.
- Slowly stir in 2 cups half-and-half, 1 tbsp vanilla extract, 1 tsp ground cinnamon, 1/4 tsp ground nutmeg, and 1/4 tsp salt until the mixture is fully emulsified.
- Pour the custard evenly over the bread cubes and use a spatula to lightly press the bread down, ensuring every piece is submerged.
- Let the dish sit for 30 minutes to soak (or cover and refrigerate for 8 hours).
- In a small bowl, cream together 2 tbsp softened butter, 3 tbsp granulated sugar, and 1 tsp ground cinnamon until a paste forms.
- Dot the cinnamon butter paste evenly across the top of the casserole.
- Bake for 40–45 minutes until the top is a rich brown-brown and the center is set with an internal temperature of 160°F (71°C).
- Remove from the oven and let the bake rest for 5–10 minutes before slicing into 8 squares.
