Making the Dough:

1. Combine warm milk, active dry yeast, and a pinch of sugar in a bowl. Let it sit for 5 minutes until frothy.
2. In a large mixing bowl, combine yeast mixture, sugar, melted butter, flour, salt, and eggs. Mix until a soft dough forms.
3. Knead the dough on a floured surface until smooth and elastic.
4. 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.

Creating the Filling:

1. Mix brown sugar and ground cinnamon in a small bowl.
2. Roll out the risen dough into a rectangle and spread softened butter evenly.
3. Sprinkle the cinnamon-sugar mixture over the buttered dough.

Rolling and Cutting:

1. Starting from the long edge, tightly roll the dough into a log.
2. Cut the log into 12 equal pieces.

Baking:

1. Place rolls in a greased baking dish, leaving space between each.
2. Cover and let rise for an additional 30 minutes.
3. Preheat oven to 350°F (180°C) and bake for 25-30 minutes or until golden brown.
