In a stand mixer, or large mixing bowl, dissolve yeast, and honey in the warm water.
Let sit for 5 minutes.
Add in the whole wheat flour, white flour, butter and salt and mix until the dough pulls away from the sides (Add in more flour 1 TBS at a time if needed)
Knead, or allow to mix with dough hook for 8 minutes.
Remove the dough from the bowl and oil the bowl.
Place dough back in the bowl and cover. Allow to rise for about 1 hour until doubled in size.
Punch the dough down and roll it on a lightly floured surface.
Divide the dough into 2 equal halves, and roll into loaves.
Place each load in a greased bread pan.
Cover and allow to rise for another 45 minutes, or so, until doubled.
Preheat the oven to 375 degrees and bake for 25-30 minutes.
Coat the tops with butter, and return to the oven for another 5 minutes.
Allow to cool, if you can wait, and slice and serve.
