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:

  1. Preheat the oven to 350°F (180°C) and grease a 9x13 inch baking dish with butter or non-stick spray.
  2. Place the 6 cups of cubed bread in a large bowl, drizzle with 4 tbsp melted butter, and toss gently to coat.
  3. Spread the buttered bread cubes evenly into the prepared baking dish.
  4. In a mixing bowl, whisk together 4 large eggs and 1/2 cup packed light brown sugar until smooth.
  5. 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.
  6. Pour the custard evenly over the bread cubes and use a spatula to lightly press the bread down, ensuring every piece is submerged.
  7. Let the dish sit for 30 minutes to soak (or cover and refrigerate for 8 hours).
  8. In a small bowl, cream together 2 tbsp softened butter, 3 tbsp granulated sugar, and 1 tsp ground cinnamon until a paste forms.
  9. Dot the cinnamon butter paste evenly across the top of the casserole.
  10. 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).
  11. Remove from the oven and let the bake rest for 5–10 minutes before slicing into 8 squares.
