In a large mixing bowl or the bowl of a stand mixer, combine 1 ½ cups of the flour, 1/4 cup granulated sugar and 1 - 0.25 oz package active dry yeast.
In a small saucepan, heat 1 cup milk, ¼ cup unsalted butter and 1 teaspoon salt to 110-115°F.
Remove from heat and add to the flour mixture; beat on low speed with electric mixer. Add in 1 large egg, mix well and scrape down the sides of the bowl. Beat the mixture for a total of 3 minutes on high speed, until smooth.
Stir in the remaining flour (1 to 1 1/2 cups) by hand, adding enough of the flour to make it a soft, but not sticky, dough.
Turn out onto a floured surface and knead until smooth and elastic, 5-8 minutes. Alternately, use the dough hook on the stand mixer and knead the mixture 2-3 minutes, or until smooth and elastic.
Shape the dough into a ball and place in a greased bowl; cover with a clean kitchen towel and let rise in a warm but not hot place until doubled in size (about 1 hour).
Punch down the dough and allow to rest 10 minutes. On a large floured surface, roll the dough into a large rectangle, about 15"-7” in size.
