**1. Prepare the Dough:**
- In a large bowl, combine warm water, yeast, and sugar. Let sit for 5-10 minutes until frothy.
- Add melted butter, salt, and flour. Mix until a dough forms. Knead for 5-7 minutes (or 3-4 minutes in a stand mixer with a dough hook) until smooth and elastic.
**2. Let the Dough Rise:**
- Transfer the dough to a greased bowl, cover with a clean towel, and let rise in a warm place for about 1 hour or until doubled in size.
**3. Shape the Breadsticks:**
- Preheat your oven to 375°F (190°C) and grease a 9x13-inch baking sheet.
- Roll out the dough into a rectangle to fit the baking sheet. Place the dough on the sheet and use a knife or pizza cutter to score it into 12 breadsticks.
**4. First Butter Coat:**
- Brush the dough generously with melted butter.
**5. Bake:**
- Bake in the preheated oven for 15-18 minutes, or until the breadsticks are golden brown on top.
**6. Season and Serve:**
- While the breadsticks are warm, brush them again with melted butter. Mix Parmesan, garlic powder, onion powder, parsley, paprika, and salt in a small bowl. Sprinkle the seasoning mixture evenly over the breadsticks.
- Cut along the scored lines and serve warm with your favorite dipping sauce.
