01 - Combine granulated sugar and active dry yeast in warm water within a mixing bowl, stirring gently. Allow to stand for 5 minutes until bubbles form.
02 - Incorporate all-purpose flour, olive oil, and salt into the yeast mixture. Mix thoroughly, then knead for 5 to 7 minutes until the dough achieves a smooth consistency. Cover and leave in a warm environment to rise for 1 hour, or until doubled in size.
03 - Preheat the oven to 400°F. Arrange parchment paper on a baking sheet.
04 - On a floured surface, roll the dough out into a rectangle measuring 10 by 14 inches.
05 - Distribute shredded mozzarella, sliced pepperoni, dried oregano, and garlic powder evenly over the dough.
06 - Starting from the long edge, roll the dough tightly into a log. Slice the log into 12 even pieces.
07 - Place each roll seam-side down on the prepared baking sheet. Brush the tops with melted butter and sprinkle with grated Parmesan cheese.
08 - Bake for 18 to 20 minutes until the breadsticks are golden brown and baked through.
09 - Serve warm, accompanied by marinara sauce for dipping if desired.
