Melt the butter in the microwave in a 1 cup glass measuring cup. Add the sugar, salt and milk and stir until the sugar and salt dissolve.

In a second glass measuring cup, measure out the water and test the temperature, either microwaving or adding ice until it measures between 105°F and 115°F. Dissolve the yeast in the warmed water.

Run warm water into the mixer bowl to heat it. Add the two measuring cups of liquids, along with 4 ½ cups of the flour.

Place the bowl in the mixing stand, and use the dough hook to mix on Speed 2 for about 1 minute. Continue to add the flour, slowly, until dough forms on the hook and cleans the sides of the bowl. Continue kneading the dough on Speed 2 for another 2 minutes. Dough will be a little sticky.

Grease a clean bowl with vegetable oil, and place the dough in this bowl to rise. Turn the dough over in the bowl so all sides are coated in oil. Cover the bowl with a towel or plastic wrap and let it rise for about an hour, or until doubled in size.

Punch the dough down and divide it in half. Shape each dough into a loaf on a parchment paper lined baking sheet. Cover again and let rise for about 1 hour more, or until doubled in size again.

Bake at 400°F for about 30 minutes.
