In a large bowl, dissolve yeast in warm milk. Add the butter, sugar, salt, eggs and 2 cups flour. Mix on medium speed for 3 minutes. Stir in the rest of flour until smooth. Cover dough in bowl and let rise in a warm place until doubled, about 30 minutes.

Stir batter vigorously for 25 strokes (dough will be slightly sticky). Spoon into greased muffin cups. Tap pans to settle the batter. Cover and let rise until batter reaches tops of muffin cups, approximately 20 minutes. In the meantime, preheat oven to 400°.

Bake 10-15 minutes or until golden brown and baked through. Brush with butter.
