Mix the flour, sugar, yeast, and salt in a large mixing bowl.
Add the warm water slowly, stirring until a dough forms.
Knead the dough on a floured surface for about 5 minutes.
Place the dough in a greased bowl, cover it, and let it rise for 1 hour or until it doubles in size.
This ensures the breadsticks will be fluffy.
Preheat your oven to 375 degrees Fahrenheit.
Punch down the dough, then divide it into 12 equal pieces.
Roll each piece into a breadstick shape.
Arrange the breadsticks on a greased baking sheet.
Combine the softened butter and garlic powder, then brush the mixture over each breadstick.
Sprinkle Parmesan on top of the breadsticks and bake them for 15 minutes or until golden brown.
Let them cool slightly before serving.
