In a small bowl, combine the warm water, yeast, and granulated sugar. Stir gently and let sit for about 5-10 minutes until frothy.
Prepare the Dough:
In a large mixing bowl or the bowl of a stand mixer, combine the flour, softened butter, and salt. Add the yeast mixture and knead the dough by hand or with a dough hook on medium speed until smooth and elastic, about 8-10 minutes.
First Rise:
Transfer the dough to a lightly greased bowl, cover with a kitchen towel, and let it rise in a warm place for about 1 hour, or until doubled in size.
Shape the Breadsticks:
Punch down the dough and divide it into 12-14 equal pieces. Roll each piece into a 6-7 inch long rope and place them on a greased or parchment-lined baking sheet.
Second Rise:
Cover the shaped breadsticks with a kitchen towel and let them rise for another 20-30 minutes until puffy.
Preheat the Oven:
Preheat your oven to 400°F (200°C).
Bake the Breadsticks:
Bake the breadsticks in the preheated oven for 12-15 minutes, or until golden brown.
Prepare the Topping:
While the breadsticks are baking, melt the 1/4 cup of unsalted butter and mix in the garlic powder and salt.
Notes
Remove the breadsticks from the oven and immediately brush them with the melted butter mixture. Serve warm.
