In a mixing bowl, combine warm milk, sugar, and yeast. Let it sit for about 5-10 minutes until it becomes frothy.

Add melted butter and the egg to the yeast mixture. Stir until well blended.

In a separate bowl, whisk together 3 ½ cups of flour and salt.

Gradually add the dry ingredients to the wet mixture. Mix until a shaggy dough forms and knead by hand or with a dough hook for about 5-7 minutes.

Place the dough in a greased bowl, cover with a kitchen towel, and let it rise in a warm place for about 1 hour.

Punch the dough down and divide it into 12 equal pieces. Shape each piece into three smaller balls and place them in greased muffin tins.

Cover the rolls with a towel and let them rise for another 30 minutes.

Preheat your oven to 375°F. Bake the rolls for 15-18 minutes, or until golden brown.

Brush with melted butter immediately after baking.
