In a large saucepan, heat the buttermilk and cheese over low heat. Stir until cheese is melted (mixture will look weird or curdled). Cool to 110° to 115°.

In a large bowl, add sugar and yeast in warm water. Let sit for about 5 minutes. Add buttermilk mixture, eggs, salt and 3 cups of flour. Beat until smooth. Stir in enough remaining flour to form a soft dough.

Put dough onto a floured surface; knead until smooth and elastic, about 6-8 minutes. Or alternately knead in using a stand mixer fitted with dough hook for 5-6 minutes.Put dough in greased bowl. Turn dough once to grease top. Cover and let rise in a warm place until doubled, about 1 hour.

Press dough down. Place on a lightly floured surface and divide in half. Roll each portion into an 18-in. x 12-in. rectangle. Brush each rectangle with half of melted butter. Top with cheese and remaining dough.

Cut into twelve 1-1/2-in. strips. Cut each strip in half and twist. Place 1 inch apart on greased foil-lined baking sheets or use non stick baking mats. Sprinkle with Parmesan cheese, if desired.

Bake at 375° for 15-20 minutes or until lightly browned. Remove to wire racks to cool. Serve warm. Refrigerate any leftovers.
