Add the first 3 ingredients to a Kitchen Aid bowl and let sit for a few minutes to activate yeast. Add the remaining ingredients and mix with the hook attachment on low speed until combined. Increase speed to medium, and mix for 2 minutes to develop gluten.
Transfer dough to an oiled stainless-steel bowl. Cover the bowl with a dish towel, and let the dough rise until doubled in size in a warm place, about 30 minutes.
Grease a 9"x13" glass baking dish; set aside.
After dough has risen, punch it down and weigh out twelve (2.75-ounce) pieces. Roll each piece into a tight ball, and place them in the prepared baking dish. Arrange the balls 4 lengthwise and 3 across, leaving equal space between each.
Cover the pan with a dish towel and let rise again in a warm place until doubled, 30 to 60 minutes.
Preheat the oven to 375°F and adjust the rack to a lower third position.
Bake rolls in the preheated oven for 8 minutes. Rotate the dish and continue baking until golden brown on top, about 8 minutes more. Remove from the oven and brush with butter.
