Grease a 9×13 baking pan with baking spray or oil. Set aside.
Combine warm water, milk, with the butter pieces, sugar, salt and microwave for about a minute. Stir until everything is melted. Add to a standing mixer.
Add about 3 ½ cups of flour, together with the yeast and mix for at medium speed, using a paddle hook. Add in enough additional flour (if needed) to make soft dough. You want the dough to be slightly stick.
Switch with hook dough and mix for about 6-8 minutes.
If mixing by hand, turn dough into floured board and mix , for about 6-8 minutes
Next divide dough into 15 pieces and roll to form balls. For even balls you might want to use a scale to measure evenly.
Place dough into 9 x 13 greased pan.
Cover with a clean cloth and let rise in a warm place (see notes ) for about 20 minutes or until doubled.
Bake rolls in at 350 Degrees F. oven for about 15-20 minutes, or until golden brown.
Remove rolls from oven and immediately brush with melted butter.
Let it cool slightly before serving.
