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

Add flour, melted butter, and salt to the yeast mixture. 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, and let it rise in a warm place for about 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 dough balls on a baking sheet lined with parchment paper. Flatten slightly.

Cover and let them rise for another 30 minutes.

Brush the tops with beaten egg for a shiny finish.

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

Remove from the oven and let cool on a wire rack.
