In a large bowl, combine warm water, instant yeast, and granulated sugar. Let sit for 5 minutes until frothy.
Add olive oil and salt. Gradually mix in all-purpose flour until a soft, slightly tacky dough forms. Add a little more flour if needed.
Transfer the dough to a lightly floured surface and knead for 3-5 minutes until it becomes smooth and elastic. Cover it with a clean tea towel and let it rise in a warm location for approximately 20 minutes until puffy.
Punch down the dough, divide it into 15 portions, and shape each portion into a log that is 7 inches long.
Place them on a parchment-lined baking sheet about 1 inch apart. Preheat the oven to 400°F and bake for 13-17 minutes until lightly golden. Mix 2 tablespoons melted butter with 1/2 teaspoon garlic powder and brush over the hot breadsticks. Serve warm.
