Directions:
1. Preheat the oven to 350 degrees F (175 degrees C).
2. Place bread pieces into an 8-inch square baking pan. Drizzle melted butter over bread and sprinkle raisins over top.
3. Whisk milk, sugar, eggs, cinnamon, and vanilla together in a medium mixing bowl until well combined. Pour mixture over bread, and lightly push down with a fork until all bread is covered and soaking up the liquid.
4. Bake in the preheated oven until golden brown and the top springs back when lightly pressed, about 45 minutes.
