Combine the hot water, honey, butter, brown sugar and salt in one bowl.
In the bowl of a stand mixer, combine together the yeast, oats, whole wheat flour, and about one cup of white flour.
Pour wet ingredients into dry, and mix for 1-2 minutes.
Stir in the additional white flour until the dough forms a ball.
Knead, by hand or in the mixer using a dough hook, for 5-7 minutes.
Let the dough rise for about an hour.
Roll into 24 balls (if dough is too sticky, flour your hands and/or add extra flour as needed) and place in a greased 9″x13″ pan. Let rise another 30-45 minutes.
Bake 350 degrees for 18-22 minutes, or until golden brown (cover with foil if necessary the last few minutes to prevent over-browning).
Brush tops of warm rolls with melted butter immediately. Serve warm with butter.
