Preheat oven to 350 degrees. Spray a regular sized muffin tin with non stick cooking spray, set aside. In a large bowl combine the milk, sugar, eggs, vanilla and cinnamon.
Gently toss in the cubed bread.
Divide the mixture between the 12 muffin cups. There should be about 1/3 cup in each cavity.
Prepare the streusel topping and sprinkle on top of the muffins. Bake for 25-30 minutes or until golden brown. Allow the muffins to cool in the pan for 5 minutes before removing.
Serve immediately with maple syrup and powdered sugar if desired.
