1. In a large mixing bowl, combine warm milk, melted butter, and sugar. Stir until sugar is dissolved.
2. Sprinkle yeast over the milk mixture and let it sit for about 5 minutes, until foamy.
3. Add flour, salt, and ground cinnamon to the bowl. Mix until a dough forms.
4. Knead the dough on a floured surface for about 10 minutes, until smooth and elastic.
5. Place the dough in a greased bowl, cover with a damp cloth, and let it rise in a warm place for about 1 hour, or until doubled in size.
6. Punch down the dough and knead in the raisins.
7. Shape the dough into a loaf and place it in a greased loaf pan. Cover and let rise for another 30 minutes.
8. Preheat oven to 375°F (190°C). Bake the bread for 35-40 minutes, until golden brown and sounds hollow when tapped.
9. Let the bread cool in the pan for 10 minutes, then transfer to a wire rack to cool completely.
