Mix yeast: In a small bowl, combine warm water and sugar, then sprinkle in the yeast. Let it sit for 5–10 minutes until foamy.

Combine ingredients: In a large bowl, whisk together the foamy yeast mixture, warm milk, melted butter, egg, and salt.

Add flour: Gradually incorporate the all-purpose flour, mixing gently until a soft dough forms.

Knead dough: Turn the dough onto a floured surface and knead for 8–10 minutes until smooth.

First rise: Place the dough in a greased bowl, cover, and let it rise for 1 to 1½ hours until doubled.

Shape rolls: Punch down the dough, divide into 12–16 portions, and roll into balls.

Second rise: Cover the shaped rolls and let them rise again for 30–45 minutes.

Preheat oven: While rolls rise, preheat your oven to 375°F.

Bake rolls: Bake for 18–20 minutes until golden brown.

Brush and serve: Brush with melted butter and serve warm.
