In a large bowl, combine the flour, cornmeal, salt, sugar, and yeast.
Add the warm water and mix until the dough begins to come together.
Add the melted butter and olive oil; mix until fully incorporated.
Knead the dough on a floured surface until smooth and elastic, about 5-7 minutes.
Place the dough in a lightly oiled bowl, cover, and let it rise in a warm area until doubled in size, about 1.5 to 2 hours.
Preheat your oven to 425°F (220°C).
Lightly oil a 12-inch pizza pan or cast iron skillet.
Press the dough into the pan, ensuring it goes up the edges and forms a crust.
Layer the mozzarella cheese over the dough.
Spread the marinara sauce over the cheese, then sprinkle with black pepper and oregano.
Bake for 20-30 minutes or until the crust is golden brown and the cheese is bubbly.
Remove from oven and let it cool slightly before slicing.
Sprinkle with grated Parmesan cheese before serving.
