Ingredients
- 1 loaf day-old brioche challah, or French bread (cubed)
- 1 ½ cups fresh or frozen blueberries
- 6 large eggs
- 2 cups milk or half-and-half
- ½ cup cream cheese optional
- ½ cup maple syrup or brown sugar
- 1 teaspoon vanilla extract
- 1 teaspoon ground cinnamon
- Topping:
- ½ cup all-purpose flour
- ½ cup brown sugar
- ½ teaspoon cinnamon
- ¼ cup cold butter cubed
Instructions
- Prepare the bread: Cut into cubes and place half in a greased 9x13-inch baking dish.
- Add blueberries: Sprinkle half over the bread, layer the rest of the bread and remaining blueberries.
- Make custard: Whisk eggs, milk, vanilla, cinnamon, and syrup until smooth. Pour evenly over the bread and press down gently.
- Prepare topping: Mix flour, brown sugar, and cinnamon; cut in butter until crumbly. Sprinkle on top.
- Chill or bake:
- For make-ahead: Cover and refrigerate overnight.
- For same-day: Let sit 30 minutes.
- Bake: Preheat oven to 350°F (175°C) and bake 40–45 minutes until golden and set.
- Serve: Rest 10 minutes before serving. Top with syrup, powdered sugar, or whipped cream.
Notes
- Slightly stale bread absorbs the custard best.
- Frozen blueberries don’t need thawing just toss with flour to prevent color bleeding.
- Add cream cheese or nuts for extra richness and texture.
- To prevent sogginess, use sturdy bread and don’t oversoak.
