Warm the milk until it reaches 110°F and froth with active yeast.

Mix in granulated sugar, one whole egg, egg yolk, and melted butter until creamy.

Gradually add bread flour and ground cinnamon, mixing to form a slightly sticky dough.

Knead the dough for 8 minutes until smooth and elastic.

Place in an oiled bowl, cover, and let rise in a warm place for 1 to 1.5 hours.

Roll out dough into a rectangle and spread with softened butter, then top with brown sugar and cinnamon.

Roll tightly into a log and slice into 9-10 equal pieces.

Let rolls rise again for 30-45 minutes in a greased pan.

Preheat oven to 350°F and bake rolls for 20-25 minutes until golden.

Prepare frosting by beating cream cheese, melted butter, powdered sugar, and vanilla together until smooth.

Frost warm rolls with cream cheese frosting and serve immediately.
