01 - Combine granulated sugar and active dry yeast in warm water, allowing the mixture to stand for 5 minutes until bubbly.
02 - Incorporate all-purpose flour, olive oil, and salt into the yeast mixture. Mix and knead by hand or with a dough hook for 5 to 7 minutes until a smooth, cohesive dough forms. Cover and set aside in a warm spot for 1 hour or until doubled in size.
03 - Preheat oven to 400°F. Line a baking sheet with parchment paper.
04 - Roll risen dough out on a floured surface into a rectangle approximately 10 by 14 inches. Distribute mozzarella, pepperoni, dried oregano, and garlic powder evenly across the dough.
05 - Starting at the long edge, tightly roll the dough into a log. Slice the rolled dough into 12 equal pieces.
06 - Place each piece seam-side down onto the prepared baking sheet. Brush the tops with melted butter and sprinkle evenly with grated Parmesan cheese.
07 - Bake in preheated oven for 18 to 20 minutes, or until breadsticks are golden-brown and fully baked.
08 - Present breadsticks warm accompanied by marinara sauce for dipping, if desired.
