Ingredients
  

  • 1 loaf brioche or challah bread cut into 1-inch cubes (stale or day-old works best)
  • 8 large eggs at room temperature
  • 2 cups whole milk (or half-and-half for extra creaminess; almond milk as a dairy-free swap)
  • 1/2 cup pure maple syrup (plus extra for drizzling)
  • 3/4 cup granulated sugar (or swap half for brown sugar for depth)
  • 2 teaspoons pure vanilla extract (look for Nielsen-Massey brand for top flavor)
  • 1 teaspoon ground cinnamon (add 1/4 teaspoon nutmeg for a warm twist)
  • 1/4 teaspoon kosher salt
  • 2 tablespoons unsalted butter cut into small pieces (plus more for greasing)
  • Optional toppings: fresh berries, toasted pecans, powdered sugar, whipped cream

Instructions
 

  • Preheat your oven to 350°F and lightly butter a 9x13-inch casserole dish. Scatter a handful of bread cubes on the bottom to check if they stick.
  • In a large bowl, whisk together eggs, milk, maple syrup, sugar, vanilla, cinnamon, and salt until smooth and frothy.
  • Gently fold the bread cubes into the custard, pressing down slightly so each piece soaks up the mixture.
  • Dot the top with small butter pieces for golden pockets and a buttery crust.
  • Cover tightly with foil and refrigerate for at least 4 hours or overnight to enhance flavor and texture.
  • Bake for 40-45 minutes until puffed and lightly browned. Let it rest before serving with desired toppings.

Notes

Bread Texture: I tested with brioche, challah, and thick-sliced bread—brioche gave the richest crumb. If bread feels dry after chilling, add extra milk and egg. Tent with foil if edges brown too quickly.
