Add sugar, salt, 1/3 cup olive oil, and 2 1/4 cups flour. Mix together with dough hook until a soft dough forms. Knead for 8-10 minutes. (if you're kneading by hand, turn onto a well-floured work surface and knead for 8-10 minutes) Add more flour as needed until dough pulls away from the sides of the bowl or still slightly sticky.
With dough wrapped on dough hook, spray bowl with butter or olive oil spray. Remove dough from hook, form into a ball, place in bowl and turn to coat the top with oil. Cover with plastic wrap and let rise for 45 minutes. (Hang onto the plastic wrap for the second rise.)
Coat a 10-inch cast-iron skillet (I've also used a round casserole dish) with 1 tablespoon olive oil. Punch down the dough and press it into the bottom of the pan. Poke multiple holes in the uncooked dough with your fingers tips. Another option is to use a sharp knife to score the top of the bread dough in a crisscross pattern.
Cover the pan loosely with plastic wrap and let the dough rise another 20 minutes.
When the bread has risen, bake, in a pre-heated oven, at 400° for 20-25 minutes.
Remove from the oven when the top is light golden brown.
Remove the bread from the skillet immediately and let cool on a rack.
Drizzle with more olive oil and cut into wedges. It's best when served while warm!
