In a small bowl, combine warm milk and yeast. Let it sit for 5 minutes until foamy.

In a large mixing bowl, combine flour, sugar, and salt. Add the melted butter, egg, and yeast mixture. Mix until a dough forms.

Knead the dough on a floured surface for about 5-7 minutes until smooth and elastic.

Place the dough in a greased bowl, cover with a cloth, and let it rise in a warm place for 1 hour or until doubled in size.

In a medium bowl, mix together brown sugar and cinnamon.

Pour the melted butter into a separate bowl.

Once the dough has risen, punch it down and tear off small pieces (about 1 inch each).

Dip each piece in melted butter, then roll in the cinnamon sugar mixture. Layer the pieces in a greased bundt pan.

Preheat the oven to 350°F (175°C).

Once all dough pieces are in the bundt pan, let it rise for another 20 minutes.

Bake for 30-40 minutes until golden brown. Let cool for 10 minutes before inverting onto a serving plate.
