In a bowl, combine the warm milk and active dry yeast. Let it sit for about 5-10 minutes until foamy.

In a large mixing bowl, combine the flour, sugar, and salt. Make a well in the center and add the yeast mixture, melted butter, and eggs.

Use a wooden spoon or electric mixer to combine everything until a dough forms. Knead on a floured surface for about 5-7 minutes until smooth and elastic.

Place the dough in a greased bowl and cover with plastic wrap or a damp towel. Let it rise in a warm place for about 1 hour, or until doubled in size.

In a bowl, mix the softened butter, brown sugar, and ground cinnamon until well combined.

Once risen, punch down the dough and roll it out on a floured surface into a rectangle about 1/4 inch thick.

Spread the cinnamon filling evenly over the dough. Then, starting from one edge, roll the dough tightly into a log.

Slice the log into 12 equal pieces and place them in a greased baking dish.

Bake at 350°F (175°C) for 25-30 minutes until golden brown.
