If you have fresh bread, place it in a large baking pan and bake in a 300°F oven about 7 minutes.
In a large mixing bowl, whisk together the milk, butter, vanilla, cinnamon, sugar and the beaten eggs and mix well.
Add bread cubes to milk mixture. Let it stand for approximately 20 minutes or until bread absorbs most of the mixture. Add the mashed banana mix well.
Pour the bread-pudding mixture into a baking pan. Bake uncovered in a 350° f oven for about 1 hour or until a knife inserted into the center comes out clean.
Remove from the oven and allow to cool completely, then refrigerate for at least 2 hours or overnight.
Notes
Be sure to use stale bead for this recipe, it's the best to soak the sauce. If you have fresh bread, just place it in the oven and bake it for about 7 minutes to make it hard.
