Preheat your oven to 200°F (95°C) to help the dough rise.

Combine flour, yeast, and salt in a large mixing bowl. In a separate bowl, heat milk, sugar, and butter until warm, then combine with dry ingredients.

Add the egg and stir until a sticky dough forms. Gradually add flour until the dough pulls away from the sides.

Knead the dough on a floured surface for about 5-8 minutes until smooth and elastic.

Place the dough in a greased bowl, cover with plastic wrap and let it rest in the warm oven for 10-20 minutes.

Prepare the filling by mixing the softened butter, brown sugar, cinnamon, and a pinch of salt until creamy.

Roll the dough into a rectangle, spread filling, roll tightly, and slice into 12 pieces.

Place rolls in a greased pan, cover, and let rise for 30 minutes in a warm place.

Preheat the oven to 350°F (175°C) and bake for 26-30 minutes until golden brown.

Mix together frosting ingredients until smooth and frost warm rolls.
