In a mixing bowl, combine the all-purpose flour, instant yeast, salt, garlic powder, and sugar.
Pour in the warm water and olive oil. Mix until a dough forms.
Knead the dough on a lightly floured surface for 5 minutes until smooth and elastic.
Place the dough in a greased bowl, cover it with a damp cloth, and let it rise in a warm place for about 10 minutes.
Preheat your oven to 425°F (220°C) and line the baking sheet with parchment paper.
Roll out the dough on a floured surface into a rectangle, about 1/4 inch thick.
Cut the dough into strips using a pizza cutter or a sharp knife.
Place the breadsticks on the baking sheet and brush them with melted butter. If desired, sprinkle with Italian herbs.
Sprinkle shredded mozzarella cheese over the breadsticks generously.
Bake in the preheated oven for 12-15 minutes or until the breadsticks are golden and the cheese is bubbly.
Remove from the oven and let cool slightly before serving.
