Combine the warm milk and yeast in a large bowl. Let it sit for 5 minutes until foamy.
Stir in the sugar, egg, 1/4 cup melted butter, and salt into the yeast mixture.
Gradually add the flour, mixing until a shaggy dough forms.
Turn the dough out onto a lightly floured surface. Knead for 5 to 7 minutes until the dough is smooth and elastic.
Place the dough in a lightly oiled bowl, turning to coat. Cover the bowl with plastic wrap and let it rise in a warm place for 30 minutes, or until doubled in size.
Gently punch down the dough. Divide it into 12 equal pieces. Roll each piece into a smooth ball.
Arrange the dough balls in a greased 9×13 inch baking pan, leaving a small space between them for rising.
Cover the pan loosely and let the rolls rise again for 15 minutes.
Preheat your oven to 375°F (190°C).
Bake for 15 to 18 minutes, or until the tops are golden brown.
Immediately brush the tops of the hot rolls with the remaining 4 tablespoons of melted butter.
Serve warm.
Notes
For extra flavor, add 1 teaspoon of garlic powder to the melted butter used for brushing.
If your kitchen is cold, place the covered dough bowl inside a turned-off oven with a pan of hot water on the rack below to create a warm environment for rising.
You can use instant yeast; if you do, mix it directly with the flour instead of proofing it with the milk first.
