Add milk and butter to microwave safe bowl. Heat 30 seconds at a time, stirring between each, until butter is melted and mixture is warm to the touch, but not scalding.
In the bowl of a stand mixer, combine yeast, salt, sugar, and 4 cups of flour. Add in melted butter and milk mixture and mix until combined. Add 1 egg and mix well.
Mix in 1.5- 2.5 cups of flour, until the dough cleans the bowl. Knead in the mixer for 5 minutes. Cover bowl with towel and let until dough has doubled; about 45 minutes- 1 hour.
Punch down the dough and divide into 4 equal balls.
Roll out each ball into a circle and brush with melted butter.
Using a pizza cutter, cut each circle into 12 wedges. Roll up each triangle from the fat end to the point. Place on a cookie sheet, with the point on the bottom and brush with melted butter.
Let rise for 30-45 minutes. Preheat oven to 375.
Bake for 10-15 minutes, until rolls are very lightly golden brown.
