Preheat oven to 350°

In a large bowl, add milk, eggs, sugar and vanilla and stir well.

Butter each piece of bread and add 6 pieces of bread to a 9x14x2 inch pan or baking dish. I used a larger pan for this.

Buttered side down.

Sprinkle a little cinnamon on top of the bread.

Add blueberries on top of bread (optional, and if you want plain bread pudding, just add the other 6 pieces of bread and omit the blueberries).

Next add the remaining 6 pieces of bread and sprinkle with a little cinnamon.

Pour milk mixture over bread and let it soak in. If you are adding in the blueberries, you can add some on top as well as the ones in between the layers of bread.

Just a note, this is really full, to the top of your dish, with milk, that is why you need a larger baking dish then the standard 9x13. Do not worry if all the milk mixture does not fit in the dish. Just use as much as you can.

Cover with foil and bake for 1 hour. After an hour, take off foil and continue baking for an additional 10-15 minutes or until done.

It might seem like a LOT of milk, but trust me, this is what makes the "custard like" pudding!
