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

In another bowl, whisk together the flour and salt.

Pour the yeast mixture into the flour mixture, then add the melted butter. Stir until the dough comes together, forming a sticky ball.

Turn the dough onto a floured surface and knead for about 5 minutes until smooth and elastic.

Place the dough in a greased bowl, cover it with a cloth, and let it rise in a warm place for about 30 minutes or until doubled in size.

Preheat your oven to 425°F (220°C). Grease your 9-inch round pan.

Roll out the dough on a floured surface to fit the pan. Place the dough in the prepared pan, pressing it up the sides to form a crust.

Spread the pizza sauce evenly over the crust. Layer with shredded mozzarella and your favorite toppings, then finish with more cheese on top.

Bake in the preheated oven for 25 minutes or until the cheese is bubbly and golden.
