Preheat your oven to 350°F (175°C). Grease an 8x8 inch baking dish.
Cut your bread into cubes. I use kitchen scissors for this. Place the cubed bread in the prepared baking dish.
In a separate bowl, whisk together the eggs first. Then add milk, cinnamon, and vanilla extract and whisk until well combined.
Pour the egg mixture over the bread in the baking dish, ensuring that all the bread is coated evenly.
Sprinkle the fresh blueberries over the top of the bread mixture.
Cover the baking dish with foil and bake for 30 minutes.
Remove the foil and bake for an additional 15 minutes, or until the top is golden brown and the center is set.
Once done, allow the casserole to cool slightly before serving.
