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

In a large bowl, combine the flour and salt. Stir to mix evenly.

Add the activated yeast mixture and olive oil to the flour mixture. Stir until a dough begins to form.

Transfer the dough to a floured surface and knead it for about 5-7 minutes until smooth and elastic.

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

While the dough is rising, preheat your oven to 475°F (245°C) and place your cast iron skillet inside to heat up.

Once the dough has risen, punch it down and roll it out on a floured surface. Carefully transfer the rolled dough to the hot cast iron skillet.

Spread pizza sauce evenly over the dough, sprinkle with mozzarella cheese, and add your choice of toppings.

Place the skillet in the preheated oven and bake for 20-25 minutes, or until the cheese is bubbly and the crust is golden brown.

Remove the skillet from the oven and let the pizza cool for about 5 minutes. Garnish with fresh basil if desired, slice, and enjoy!
