In a large bowl, combine boiling water and oats; let stand until warm (110°-115°). In a small bowl, dissolve yeast in warm water; add to oat mixture. Add honey, butter, salt and 2 cups flour; beat until smooth. Add enough remaining flour to form a soft dough.
Turn onto a floured surface; knead until smooth and elastic, about 6-8 minutes. Place in a greased bowl, turning once to grease top. Cover and let rise in a warm place until doubled, about 1 hour.
Punch the dough down. Shape into a loaf; place in a greased 8x4-in. loaf pan. Brush with melted butter. Sprinkle with oats. Cover and let rise in a warm place until doubled, about 30 minutes.
Preheat oven to 350°. Bake 50-55 minutes or until golden brown. Remove from pan to a wire rack to cool.
