In a mixing bowl, combine warm water and granulated sugar. Sprinkle active dry yeast over the top and let it sit for about 5-10 minutes until foamy.
In another bowl, whisk together all-purpose flour, white whole wheat flour, and salt.
Once the yeast mixture is frothy, add olive oil and the flour mixture. Stir with a spoon until a shaggy dough forms.
Transfer the dough to a floured surface and knead for about 5-7 minutes until smooth and elastic.
Place the dough in a lightly oiled bowl, cover with a kitchen towel, and let it rise in a warm place for about 1 hour.
Preheat your oven to 400°F (200°C) and place your cast-iron skillet in the oven to heat up.
Once the dough has risen, gently punch it down and transfer it to the hot skillet. Stretch and spread the dough to fit the skillet.
Brush the dough with melted butter and sprinkle ground black pepper, garlic powder, and Italian seasoning over the top. Add any favorite toppings.
Cover the skillet with a kitchen towel and let it rise for another 20-30 minutes.
Once puffed up, place the skillet in the oven and bake for 20-25 minutes until golden brown.
Remove from the oven, let cool for a few minutes, slice, and serve warm.
