In a large bowl, combine the warm milk, sugar, and yeast. Let sit for 5 minutes until foamy.
Add the melted butter, egg, salt, and flour. Mix until a dough forms.
Knead the dough on a lightly floured surface for about 8 minutes until smooth.
Place the dough in a greased bowl, cover, and let rise for 1 hour, or until doubled in size.
