Step 1

Lightly grease a 9x13 inch baking dish. Arrange half the bread cubes in the dish, and top with cream cheese cubes. Sprinkle 1 cup blueberries over the cream cheese, and top with remaining bread cubes.

Step 2

In a large bowl, mix the eggs, milk, vanilla extract, and syrup. Pour over the bread cubes. Cover, and refrigerate overnight.

Step 3

Remove the bread cube mixture from the refrigerator about 30 minutes before baking. Preheat the oven to 350 degrees F (175 degrees C).

Step 4

Cover, and bake 30 minutes. Uncover, and continue baking 25 to 30 minutes, until center is firm and surface is lightly browned.

Step 5

In a medium saucepan, mix the sugar, cornstarch, and water. Bring to a boil. Stirring constantly, cook 3 to 4 minutes. Mix in the remaining 1 cup blueberries. Reduce heat, and simmer 10 minutes, until the blueberries burst. Stir in the butter, and pour over the baked French toast
