Combine 3/4 cup flour, undissolved yeast, sugar and salt in a large bowl. Heat milk, water and butter until very warm. Add to flour mixture. Beat 2 minutes at medium speed of electric 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 7 equal pieces; shape into balls. Place in greased 8-inch round pan. Cover; let rise in warm, draft-free place until doubled in size, about 30 minutes, Sprinkle in sesame seeds (optional).

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.
