01 - In a mixing bowl, dissolve granulated sugar and active dry yeast in warm water. Allow the mixture to stand for 5 minutes until foamy.
02 - Add all-purpose flour, olive oil, and salt to the yeast mixture. Mix until the dough forms, then knead on a floured surface for 5 to 7 minutes until smooth and elastic. Cover and let rise in a warm location for 1 hour until doubled in size.
03 - Preheat oven to 400°F. Line a baking sheet with parchment paper.
04 - Roll the dough out on a floured surface into a 10 by 14-inch rectangle. Evenly scatter shredded mozzarella cheese, sliced pepperoni, dried oregano, and garlic powder across the surface.
05 - Starting along the long edge, tightly roll up the dough into a log. Slice crosswise into 12 equal pieces.
06 - Arrange each roll, seam-side down, on the prepared baking sheet. Brush each with melted butter and generously sprinkle with grated Parmesan cheese.
07 - Bake for 18 to 20 minutes until breadsticks are golden brown and cooked through.
08 - Serve warm with marinara sauce for dipping if desired.
