(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

Directions

Spray a 9×13 inch pan with nonstick spray. Add the bread cubes into the prepared baking pan and top evenly with blueberries. Set aside.
In a large bowl, whisk the eggs, milk, cinnamon, brown sugar, and vanilla together until fully combined. Pour this mixture evenly over the bread cubes. Cover the pan and refrigerate for at least 8 hours or overnight.
When ready to bake, preheat the oven to 350°F (175°C). Remove the pan from the refrigerator and uncover it.
For the topping: In a medium bowl, combine the brown sugar, flour, and cinnamon. Cut in the cold butter using a pastry blender until the mixture resembles coarse crumbs. Sprinkle the topping evenly over the casserole.
Bake for 45-55 minutes, or until golden brown on top. If you want an extra crispy top, broil for 1 minute.
Serve hot with pure maple syrup and extra blueberries on the side.
