Mix/knead dough using your favorite method, with a mixer, by hand, or a bread machine.
You can start by mixing 1½ cups of the flour, sugar, yeast, salt, water, butter, & egg for about 2 minutes. Add in remaining flour & continue kneading/mixing until soft dough forms.
Cover & let rise 1 hour or until doubled in size. Roll out to form an 12x6" rectangle. Cut into 3 pieces 12x2" long. Roll out each piece until rounded.
Start at the top & braid the 3 pieces together. Pinch the ends of the loaf off so they stick together. Let rise 1 hour or until almost doubled in size.
Preheat oven to 400 degrees. Bake for 12-15 minutes or until the top & bottom are golden brown. Remove from oven & brush with butter if desired.
