Activate the Yeast: Combine 1 cup of warm milk with 1 tablespoon of sugar. Sprinkle 2 teaspoons of active dry yeast. Let sit for 5-10 minutes until foamy.

Prepare the Dough: In a stand mixer, combine 4 cups of flour and 2 teaspoons of salt. Add the yeast mixture, 1 beaten egg, and 4 tablespoons of butter. Mix until a smooth dough forms, about 7-8 minutes.

Let the Dough Rise: Transfer to a greased bowl, cover, and let rise in a warm place until doubled, about 1 to 1.5 hours.

Roll Out the Dough: Punch down the risen dough, turn onto a floured surface, and roll into a rectangle about ¼-inch thick. Brush with melted butter.

Add the Filling: Layer shredded mozzarella and grated parmesan on the dough, followed by minced garlic and fresh herbs. Season to taste.

Create the Swirl: Roll the dough into a log shape. Slice the log lengthwise and twist the two halves together, keeping the filling side up.

Shape and Proof: Shape into a spiral and place in a greased loaf pan. Cover and proof for 30-40 minutes.

Preheat and Brush: Preheat oven to 350°F. Brush the dough with a beaten egg and sprinkle with extra herbs or cheese if desired.

Bake the Bread: Bake for 30-35 minutes until golden brown and a toothpick comes out clean.

Cool and Slice: Cool in the pan for 10 minutes, then transfer to a rack to cool completely before slicing.
