  • Total Time: 9 hours (with chilling)
  • Yield: 8 servings

Ingredients

  • Cream Cheese Mixture:
  • 8 oz cream cheese, softened
  • 1 cup powdered sugar
  • 2 tablespoons milk
  • 1 tablespoon vanilla extract (split use)
  • 1 cup blueberries
  • Bread Layers:
  • 2 loaves cubed French bread (day-old or slightly stale)
  • Egg Mixture:
  • 2 cups milk
  • 8 large eggs
  • 1 teaspoon cinnamon
  • 1/2 teaspoon ground nutmeg
  • 1 teaspoon vanilla extract
  • 1 cup blueberries (for topping)

Instructions

  1. Make the Cream Cheese Mixture: Beat cream cheese, powdered sugar, 2 tbsp milk, and 1 tsp vanilla until smooth. Gently fold in 1 cup blueberries.
  2. Assemble: Grease a 10×14-inch baking dish. Add half the cubed bread. Spread cream cheese mixture evenly. Top with remaining bread cubes.
  3. Egg Mixture: Whisk milk, eggs, cinnamon, nutmeg, and 1 tsp vanilla. Pour over bread layers. Press gently to soak. Top with remaining 1 cup blueberries.
  4. Chill: Cover tightly and refrigerate overnight (at least 8 hours).
  5. Bake: Remove from fridge and rest at room temp for 30–60 minutes. Bake at 375°F covered for 45 minutes. Uncover and bake another 30 minutes until golden and set.
  6. Serve: Let cool slightly before slicing. Optionally drizzle with icing or maple syrup before serving.

Notes

  • Use challah, brioche, or Texas toast for variation.
  • Substitute mascarpone or ricotta for cream cheese.
  • Try mixed berries or raspberries instead of blueberries.
  • Add a dash of cardamom or ginger for a spiced twist.
  • Top with powdered sugar glaze or cream cheese icing for extra sweetness.
