In a small bowl, combine warm milk, honey, and active dry yeast. Stir gently and let sit for 5 to 10 minutes until frothy.

In a large mixing bowl, blend rolled oats, all-purpose flour, ground cinnamon, and salt using a whisk.

Pour the yeast mixture into the dry ingredients and add melted butter. Stir until it forms a shaggy dough, then knead for 5 to 7 minutes.

Place the kneaded dough in a greased bowl and cover with a towel. Let it rise in a warm place for about 1 hour.

Punch down the risen dough and shape it into a loaf. Place it in a greased 9x5 inch loaf pan.

Cover the loaf and let it rise for another 30 minutes until puffed.

Preheat the oven to 350°F (175°C) and bake for about 35 minutes until golden brown.

Remove from the oven and cool in the pan for 10 minutes, then transfer to a wire rack for at least 30 minutes.
