Ingredients
 

Main Ingredients

  • 8 cup day-old brioche or challah, cut into cubes
  • 1.5 cup ripe bananas, mashed
  • 1 cup eggs, beaten
  • 1.5 cup whole milk
  • 0.5 cup heavy cream
  • 0.5 cup packed brown sugar
  • 2 tbsp granulated sugar
  • 2 tsp vanilla extract
  • 1.5 tsp ground cinnamon
  • 0.25 tsp ground nutmeg
  • 0.5 tsp kosher salt
  • 3 tbsp unsalted butter, melted divided
  • 0.5 cup chopped pecans or walnuts optional
  • 0.25 cup maple syrup for serving

Instructions

Preparation Steps

  • Heat oven to 350°F. Brush a 9x13-inch baking dish with 1 tbsp melted butter.
  • Spread the bread cubes in the dish. Drizzle with 1 tbsp melted butter and toss to coat.
  • Whisk the eggs, milk, cream, mashed bananas, brown sugar, granulated sugar, vanilla, cinnamon, nutmeg, and salt until smooth.
  • Pour the custard over the bread. Gently press so all cubes soak evenly. Rest 10 minutes.
  • Sprinkle nuts on top if using. Drizzle remaining 1 tbsp melted butter over the surface.
  • Bake 35–40 minutes, until puffed, golden, and the center is set.
  • Cool 10 minutes. Slice and serve warm with maple syrup.

Notes

Variation: Swap half the brioche for cinnamon-raisin bread, or fold in chocolate chips before baking. To prep ahead, assemble and refrigerate overnight; bake straight from the fridge, adding 5–10 minutes as needed. Leftovers keep 3–4 days chilled; rewarm covered at 300°F.
