Combine flour, undissolved yeast, sugar and salt in a large bowl.
Heat milk, water and butter until very warm (120 degrees to 130 degrees F). Add to flour mixture. Beat 2 minutes in your stand mixer, scraping bowl occasionally. Add 1/4 cup flour; beat 2 minutes at high speed. Stir in enough remaining flour to make soft dough.
Knead on lightly floured surface until smooth and elastic, about 8 to 10 minutes. Cover; let rest 10 minutes.
Divide dough into 12 equal pieces; shape into balls. Place in greased 8-inch round pan. Cover; let rise in warm place until doubled in size, about 30 minutes.
Bake in preheated 375 degrees F oven for 20 minutes or until done. Remove from pan; brush with additional melted butter, if desired. Serve warm.
