Dissolve the yeast in the warm water. Add honey and mix well.
Stir in the whole wheat flour, salt, vegetable oil, and butter and mix until a stiff dough has formed. Gradually work the all-purpose flour into the mix, one cup at a time.
Turn the dough onto a lightly floured countertop, and knead for about fifteen minutes. When it reaches the point where it's sort of elastic, shape it into a ball and place it into an oiled bowl. Cover with a warm, damp cloth, and allow to sit and rise until it's doubled in size -- usually about 45 minutes.
