Place milk into a large measuring cup. Heat in the microwave until warmed. Stir granulated sugar and active dry yeast into the warm milk. Let sit for 10 minutes.
In a large bowl, combine flour and salt. Add in melted butter, egg and the yeast mixture. Mix until a dough forms.
Dump dough out onto a floured surface. Knead dough until smooth, adding in more flour as needed. Place dough into a large greased bowl, cover with a towel or plastic wrap and let rise in a warm place for 1-2 hours, or until doubled in size.
Preheat oven to 400 F. Deflate dough and divide in half. Roll out each half of the dough into a large circle. Spread each half with 2 tablespoons of the softened butter. Cut each half into 12 even triangles using a pizza cutter.
Roll up and form each into a crescent. Place crescent rolls onto greased baking sheets. Cover and let rise for another 30-60 minutes. Bake for 12-15 minutes, until golden browned.
