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

Add melted butter, salt, and flour gradually. Mix until a dough forms.

Knead the dough on a floured surface for about 8-10 minutes until smooth and elastic.

Place the dough in a greased bowl, cover with a cloth, and let it rise in a warm place for 1 hour or until doubled in size.

Preheat the oven to 375°F (190°C).

Punch down the risen dough and divide it into 4 equal pieces. Shape each piece into a ball.

Place the shaped dough on a baking sheet lined with parchment paper. Cover and let rise for another 30 minutes.

Brush the tops with beaten egg for a shiny finish.

Bake in the preheated oven for 15-20 minutes until golden brown.

Remove from oven and let cool on a wire rack before serving.
